Ganoderma applanatum

Ganoderma applanatum, commonly known as the artist's conk or bear bread, is a perennial bracket fungus belonging to the family Ganodermataceae, characterized by its large, shelf-like fruiting body that grows up to 30 cm across and 10–14 cm deep, featuring a dull brownish-gray, furrowed, and unvarnished cap, a white to grayish pore surface with 4–6 pores per mm that bruises brown upon handling, and thin, woody, cinnamon-brown flesh.^[1]^[2] It produces brown to orangish-brown spores measuring 6–9 × 4–5 µm, ellipsoid and double-walled, and exhibits a trimitic hyphal system with clamp connections.^[1] This fungus is widely distributed across temperate and tropical regions worldwide, including throughout North America, Europe, and Asia, where it thrives in forested habitats as both a parasitic and saprotrophic organism on hardwood trees such as maples, beeches, oaks, and stumps.^[1]^[2] Ecologically, G. applanatum plays a key role in forest decomposition by causing a white mottled rot, breaking down lignin and cellulose in wood, which facilitates nutrient cycling and habitat creation for other organisms; it typically appears singly or in overlapping groups at the base of living or dead hardwoods, persisting for multiple years with annual layers of new tubes.^[1]^[2] In some cases, it can act as a pathogen, contributing to butt rot in trees, though it is more commonly saprobic on decaying wood.^[2] Beyond its ecological significance, Ganoderma applanatum has notable cultural and practical uses, including as an "artist's fungus" where its bruising pore surface allows for etching drawings that remain visible after drying.^[1] It is also recognized for its medicinal potential, containing bioactive compounds such as polysaccharides, triterpenoids (e.g., ganoderic acids and applanoxidic acids), steroids, and ergosterol, which contribute to a range of pharmacological activities.^[3] Traditional uses in Asian folk medicine include treatments for rheumatism, tuberculosis, pain relief, and immune enhancement, with modern studies confirming properties like antitumor effects (e.g., β-D-glucan polysaccharides inhibiting sarcoma in mice), antioxidant activity (scavenging hydroxyl radicals and inhibiting lipid peroxidation), antibacterial action against gram-positive and gram-negative bacteria, antiviral effects against vesicular stomatitis virus, anti-inflammatory responses, antidiabetic potential (aldose reductase inhibition), hepatoprotective benefits, and neuroprotective qualities.^[3]^[4] These attributes are supported by extracts showing hypoglycemic, hypolipidemic, and liver enzyme-lowering effects in diabetic rat models, underscoring its value in ethnopharmacology and potential for therapeutic applications.^[4]

Taxonomy and nomenclature

Classification

Ganoderma applanatum belongs to the kingdom Fungi, phylum Basidiomycota, class Agaricomycetes, order Polyporales, family Ganodermataceae, and genus Ganoderma.^[5] This placement reflects its characteristic basidiomycetous spore-producing structures and wood-decaying lifestyle typical of polyporoid fungi.^[6] The species was originally described by Christiaan Hendrik Persoon in 1800 as Boletus applanatus in his work Observationes Mycologicae.^[7] In 1889, Narcisse Théophile Patouillard transferred it to the genus Ganoderma, establishing the current binomial Ganoderma applanatum (Pers.) Pat., based on shared morphological features such as the woody basidiome and double-walled basidiospores.^[8] This reclassification aligned it with other non-laccate Ganoderma species, distinguishing it from earlier placements in genera like Fomes or Polyporus.^[9] Phylogenetic studies have confirmed G. applanatum's position within the Ganodermataceae using multi-locus analyses, including the internal transcribed spacer (ITS) region of nuclear ribosomal DNA, large subunit (LSU) rDNA, translation elongation factor 1-α (TEF1α), and RNA polymerase II subunit 2 (RPB2).^[5] For instance, sequence data from ITS and other markers place G. applanatum in a distinct clade within Ganoderma, often part of the G. applanatum-australe species complex, supporting its monophyletic grouping with related wood-rotting basidiomycetes.^[10] These genetic analyses, drawing from global collections, underscore the species' cosmopolitan distribution and evolutionary divergence estimated at least 30 million years ago.^[10]

Synonyms and etymology

The basionym of Ganoderma applanatum is Boletus applanatus Pers., described by Christiaan Hendrik Persoon in his Observationes mycologicae (volume 2, page 2) published in 1800. The species was subsequently transferred to the genus Ganoderma by Narcisse Théophile Patouillard in 1889, establishing the currently accepted name Ganoderma applanatum (Pers.) Pat. Key synonyms include Fomes applanatus (Pers.) Gillet, published in Les Hyménomycètes in 1878, and Elfvingia applanata (Pers.) Karst., described by Petter Adolf Karsten in 1889. Another historical synonym is Polyporus applanatus (Pers.) Wallr., published in 1833, reflecting early classifications within the polypore fungi before the modern taxonomic framework.^[9] The genus name Ganoderma derives from the Greek words ganos (γάνος), meaning "brightness" or "shining," and derma (δέρμα), meaning "skin," alluding to the glossy, varnished appearance of the fruiting bodies in many species of the genus.^[9] The specific epithet applanatum comes from the Latin applanatus, the past participle of applanare, meaning "flattened" or "leveled," which refers to the typically flat or shelf-like form of the basidiocarp.^[11] As of 2025, Ganoderma applanatum remains the accepted name with no major taxonomic revisions; phylogenetic studies on the genus Ganoderma in regions such as Central America and the Western Ghats have confirmed its distinct identity within the G. applanatum-australe species complex, supporting the stability of its nomenclature.^[12]

Description

Morphology

Ganoderma applanatum produces perennial, woody, shelf-like basidiocarps that are sessile and typically measure 3–30 cm wide by 5–30 cm long and 1–10 cm thick, with a hard, leathery to corky texture.^[13] The pileus is subcircular to fan-shaped (subdimidiate), with a dull brown to grayish-brown upper surface that is uneven, concentrically zonate, furrowed, and often lumpy or tuberculate.^[2] The margin is initially white and soft, 2–3 mm thick, becoming blunt and hardened with age.^[14] The pore surface is white to pale yellowish when fresh, featuring 4–6 angular pores per mm, but it turns grayish-brown with age and bruises dark brown upon injury.^[2] The context is duplex and up to 3 cm thick, with a lower fibrous to pithy layer and an upper woody layer, both reddish-brown in color.^[14] Microscopically, the hyphal system is trimitic, comprising generative hyphae that are thin-walled, hyaline, clamped, and 2–4 µm in diameter; skeletal hyphae that are thick-walled, yellowish-brown, and aseptate; and binding hyphae that are thick-walled, hyaline, aseptate, and frequently branched.^[15]^[2] The basidiospores are ellipsoid to ovoid, brown, double-walled with a smooth exospore and distinctly wrinkled endospore, measuring 7–10 × 5–6 µm, and featuring a truncate apex.^[15] In cross-section, the basidiocarp reveals multiple concentric layers of tube pores, corresponding to annual growth increments that reflect its perennial development and age.^[9]

Similar species

Ganoderma applanatum can be confused with other bracket fungi due to its perennial, woody growth on hardwoods, but it is distinguished by its dull, unvarnished cap surface and white pore surface that bruises brown upon handling.^[1] One close look-alike is Ganoderma tsugae, which shares a similar bracket form but features a shiny, laccate (varnished) cap surface in shades of reddish-brown, along with a more pronounced stem and growth primarily on conifers such as eastern hemlock.^[16] In contrast, G. applanatum lacks any varnish on its furrowed, lumpy, dull brown cap and prefers a broader range of hardwoods like oak and maple, with pores measuring about 4–6 per millimeter.^[1] Field identification tip: G. tsugae bruises to light brown on the pore surface, less intense than the dark brown bruising of G. applanatum, and habitat overlap is minimal since G. tsugae rarely occurs on hardwoods.^[17] Another potential confusion arises with Fomes fomentarius, the hoof fungus, which also forms large, perennial brackets but has a smoother, zonated cap with a grayish to black exterior and prefers birch or beech trees.^[18] Distinguishing traits include F. fomentarius's larger pores (2-4 per millimeter) and pore surface that yellows with age but does not bruise brown as readily as G. applanatum's. The spore print of F. fomentarius is pale lemon, unlike the rusty brown print of G. applanatum.^[19] In overlapping habitats like temperate forests, check substrate specificity—F. fomentarius favors specific hardwoods with less decay—and test bruising: G. applanatum's pores turn distinctly brown quickly, aiding rapid differentiation.^[20] Heterobasidion annosum, a root pathogen, may resemble young G. applanatum brackets with its irregular, brown to black cap and white pore surface, but it is annual rather than perennial and often features a resiny, crust-like margin.^[21] Key differences include H. annosum's white spore print and lack of brown bruising on the pores, which remain white when scratched, compared to G. applanatum's brown bruising and rusty brown spores.^[22] Additionally, H. annosum targets conifers like pines, causing root rot, while G. applanatum is specific to hardwoods and causes white rot higher on trunks.^[23] For field tips in mixed forests, examine growth habit (annual vs. layered perennial) and substrate (conifers vs. hardwoods), with the bruising reaction serving as a definitive test.^[24]

Distribution and habitat

Geographic range

Ganoderma applanatum is native to the temperate and boreal regions of the Northern Hemisphere, spanning North America, Europe, and Asia. In North America, it is widespread across forest regions of the United States and Canada, particularly abundant in eastern deciduous forests and the Pacific Northwest, where it occurs on hardwoods from coast to coast.^[2] In Europe, the fungus is commonly found in woodlands throughout the continent, with documented occurrences in countries including Austria, Bulgaria, Denmark, France, Germany, Hungary, Italy, the Netherlands, and the United Kingdom.^[25] Across Asia, it inhabits similar temperate zones, contributing to its broad native range in the hemisphere.^[26] The species exhibits a cosmopolitan distribution, with verified records extending beyond its native range to all continents except Antarctica. In the Southern Hemisphere, occurrences have been reported in Australia, particularly in regions like Western Australia (e.g., Jarrah Forest and Warren subregions), likely resulting from introductions via international trade or long-distance spore dispersal.^[27]^[28] Molecular studies indicate historical long-distance dispersal events contributing to its global presence, including in subtropical and tropical areas outside the core temperate zones.^[29] As of 2025, no major range expansions attributable to climate change or trade have been widely documented, though ongoing monitoring through biodiversity databases like GBIF shows continued detections in urban and managed forests worldwide, suggesting potential gradual spread facilitated by human activities.^[13] Distribution maps from these sources highlight its prevalence in hardwood-dominated ecosystems, with highest densities in native Northern Hemisphere habitats.^[13]

Substrate preferences

_Ganoderma applanatum exhibits a marked preference for hardwood trees, particularly species such as oak (Quercus spp.), beech (Fagus sylvatica), maple (Acer spp.), birch (Betula spp.), and ash (Fraxinus spp.), where it causes root and butt rot.^[30] While primarily associated with deciduous hardwoods, it occasionally colonizes conifers, though such instances are rare and typically occur in regions with mixed forests.^[31] This selectivity reflects the fungus's adaptation to the lignin-rich wood of these substrates, enabling efficient decay processes. The fungus thrives as both a parasite on living trees and a saprophyte on dead or decaying wood, frequently emerging at the base of trunks, on stumps, or along large roots where moisture accumulates.^[32] In urban and forest settings, it often targets stressed or wounded trees, with fruiting bodies forming in tiered clusters on these sites. This dual lifestyle allows G. applanatum to persist across various stages of wood decomposition. Optimal growth occurs in humid, shaded forest environments that maintain high moisture levels, such as densely canopied woodlands near water sources.^[33] It is commonly found up to altitudes of around 3600 meters, with records up to 3650 meters in Nepal, where cooler, moist conditions support sporulation in late summer and autumn.^[34]

Ecology

Life cycle

The life cycle of Ganoderma applanatum commences with the dispersal of basidiospores from mature fruiting bodies, primarily via wind currents, landing on suitable woody substrates such as decaying hardwoods or wounds on living trees.^[35] These spores, measuring 6–9 × 4–5 µm and ellipsoid with a truncated base, germinate under moist conditions to produce haploid hyphae.^[1] Hyphae of compatible mating types fuse to form a dikaryotic mycelium, which penetrates and colonizes the substrate, establishing extensive networks within the wood and initiating white rot decay for nutrient acquisition.^[36] This mycelial phase can persist indefinitely in favorable environments, growing saprobically on dead wood or parasitically on stressed trees.^[37] In late summer to fall, under suitable temperature and humidity, the mycelium differentiates to produce perennial fruiting bodies (basidiocarps) on the exterior of the host, typically as shelf-like brackets up to 30 cm wide.^[1] These structures are woody and persistent, forming initially as a single layer but expanding annually by adding new tube layers (0.5–2 cm deep) beneath the previous ones, each separated by brownish tissue; this layered growth maintains spore production over multiple seasons.^[1]^[38] Spores develop on basidia lining the pore surface of the active (lowermost) tube layer, with a large bracket (900 cm² pore area) capable of releasing up to 3 billion spores per day, which drop vertically before wind dispersal.^[38] The fruiting bodies exhibit a lifespan of up to 50 years or more, continuing to add annual layers and produce spores even after the host tree falls, contributing to the fungus's long-term persistence in forest ecosystems.^[39]

Ecological interactions

Ganoderma applanatum functions primarily as a white-rot decay specialist, enzymatically breaking down lignin and cellulose in the heartwood and sapwood of hardwood trees, which facilitates the decomposition of woody substrates.^[40] This process results in a mottled white rot that weakens tree structure, often entering through wounds, branch stubs, or root damage on the lower trunk and roots of species such as oaks, maples, and beeches.^[41] As a pathogen, it contributes to heartwood rot in living trees, particularly stressed or mature individuals, potentially leading to tree failure, though it more commonly acts as a saprophyte on dead or dying wood.^[42] In forest ecosystems, G. applanatum plays a vital role in nutrient cycling by degrading complex lignocellulosic materials, releasing essential nutrients like carbon, nitrogen, and phosphorus into the soil for uptake by other plants and microbes.^[43] This decomposition supports forest regeneration and maintains soil fertility, with the fungus's perennial fruiting bodies producing up to 1.25 billion spores per hour over several months, aiding widespread dispersal and colonization.^[43] The resulting decayed wood enhances habitat heterogeneity, creating cavities and microhabitats that benefit biodiversity. The fungus interacts with invertebrates by providing breeding and feeding sites within its fruiting bodies and decayed substrates, hosting saproxylic insects such as forked fungus beetles (Dendroides concolor) and spore-feeding species like Zearagytodes maculifer, though the latter's consumption reduces spore germination without evidence of mutualism.^[44]^[45] These interactions support insect populations in old-growth forests, indirectly benefiting higher trophic levels. G. applanatum does not form primary mycorrhizal symbioses, focusing instead on saprotrophic and weakly pathogenic relationships with trees.^[35]

Bioactive compounds

Chemical composition

Ganoderma applanatum contains a diverse array of bioactive and structural compounds, primarily polysaccharides, triterpenoids, sterols, proteins, and terpenes.^[46] Polysaccharides, particularly beta-glucans, constitute a major component, with total glucan content reaching up to 35% of the dry weight in fruiting bodies.^[47] These polysaccharides often include water-soluble forms rich in glucose and mannose, extracted via hot water or enzymatic methods, exhibiting variations based on extraction techniques.^[48] Triterpenoids, such as ganoderic acids A and C15-tetraol, as well as applanoxidic acids A–D, are prominent secondary metabolites, contributing to the fungus's chemical profile and isolated through ethanol or methanol extraction.^[46]^[49] Sterols, including ergosterol peroxide, are present in notable quantities and can be obtained via solvent extraction, supporting structural integrity.^[46] Proteins account for 15-21% of the dry weight, with specific immunomodulatory proteins like FIP-gap1 and FIP-gap2 identified in fruiting bodies, their levels influenced by growth substrates such as wood or synthetic media.^[50]^[46] Terpenes, including dihydroactinidiolide—a compound responsible for the fungus's characteristic fragrance—are biosynthesized during submerged cultivation from precursors like beta-carotene.^[51] Recent analyses from 2024 highlight high carbohydrate content at 33.63 ± 0.66% of dry weight, alongside elevated antioxidants such as phenolics (22.9 mg GAE/g) and flavonoids (15.84 mg QE/g), determined through methanol extraction and spectroscopic assays, with compositions varying by growth stage and environmental substrate.^[50] Overall, these compounds' concentrations fluctuate with factors like maturation phase and cultivation conditions, underscoring the need for standardized extraction protocols.^[52]

Pharmacological properties

Ganoderma applanatum exhibits a range of pharmacological properties, largely derived from its polysaccharides and triterpenoids, which have been evaluated in preclinical studies for potential therapeutic applications. These compounds contribute to immunomodulation, anti-inflammatory and antioxidant effects, anticancer activity in vitro, and antimicrobial actions against bacteria and fungi.^[46] Polysaccharides from G. applanatum, including exobiopolymers composed of 58.9% sugars and 17.1% proteins, demonstrate immunomodulatory effects by enhancing immune responses in animal models. They increase spleen and liver weights, boost natural killer (NK) cell activity, and promote complement regulation, alongside stimulating splenocyte viability, IL-2 release, and IFN-γ expression through fungal immunomodulatory proteins like FIP-gap1 and FIP-gap2.^[46] Exopolysaccharides specifically induce TNF-α production (752.17 pg/mL after 6 hours) and IL-6 secretion (328.5 pg/mL after 24 hours) in THP-1-derived macrophages at concentrations up to 228.5 µg/mL, without exhibiting toxicity to these cells.^[48] Triterpenoids in G. applanatum, such as ganoderic acid A, provide anti-inflammatory effects by reducing oxidative stress and inflammatory markers in cellular models.^[46] These compounds, along with associated phenolics in ethanolic extracts, exhibit strong antioxidant activity, including DPPH radical scavenging (77.5–81.9% at 0.1–1.0 mg/mL), iron chelation (15.7–89.0% at 0.1–20 mg/mL), and inhibition of lipid peroxidation (73.9–74.3% at 5.0–20.0 mg/mL).^[46] In vitro assays reveal the anticancer potential of G. applanatum extracts, which inhibit tumor cell growth through apoptosis induction. Methanolic extracts show selective cytotoxicity against hepatocellular carcinoma (HepG2) cells (IC₅₀ of 95.65 µg/mL), epidermoid carcinoma (A431) cells, and alveolar carcinoma (A549) cells, mediated by mitochondrial membrane potential disruption, DNA fragmentation, and inhibition of the anti-apoptotic Bcl-2 protein.^[53] Ethanol extracts, containing triterpenoids like ganoderic acid A and C15-tetraol, suppress gastric cancer (SGC-7901) cell proliferation by 55.4–62.9% at 300 µg/mL.^[46] Extracts of G. applanatum possess antimicrobial activity, particularly against Gram-positive and Gram-negative bacteria as well as fungi. Methanol and ethanol extracts inhibit growth of Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Mycobacterium smegmatis with inhibition zones up to 3.21 mm, and minimum inhibitory concentrations (MICs) of 0.003–2.0 mg/mL for lanostane triterpenoids.^[54] Antifungal effects target Candida albicans, Sporothrix schenckii, and Colletotrichum gloeosporioides, achieving up to 64% inhibition of Fusarium oxysporum and Alternaria alternata via membrane disruption by triterpenoids and polysaccharides.^[54] A 2024 study on wild G. applanatum from India identified a diverse array of bioactives, including polysaccharides and triterpenoids, underscoring their broad pharmacological potential for drug development.^[55]

Human uses

Artistic applications

Ganoderma applanatum, commonly known as artist's conk, derives its name from the unique properties of its pore surface, which is initially white and bruises to a dark brown color when scratched or etched, enabling the creation of permanent ink-like drawings directly on the fungus.^[1] This bruising reaction occurs due to the oxidation of compounds in the hyphae, producing lasting marks that do not fade over time.^[56] The mature brackets, typically harvested from hardwood trees, provide a sturdy, canvas-like medium that has been utilized for artistic expression for centuries.^[56] To prepare the fungus for artistic use, foragers select mature specimens during the growing season from late spring to early fall, cutting them carefully with a sharp knife while handling only the sides to avoid unintended bruising on the underside.^[56] The bracket is then dried naturally with the pore surface facing upward, often in a well-ventilated area, to preserve the artwork; some artists apply a light sealant for added protection, though this is not always necessary as the markings remain intact for years indoors.^[57] Drawings are made using sharp tools such as styluses, sticks, or even pyrography burners on dried pieces, allowing for intricate designs from simple sketches to detailed illustrations.^[58] Historically, the fungus served as a natural medium for etchings and crafts, with examples appearing in traditional woodland art and later in modern applications like decorative items sold in craft markets.^[1] Contemporary artists have elevated its use, such as Marie Heerkens, who employs pyrography on dried artist's conk to create unique, mycologist-collected pieces blending fungal texture with burned patterns.^[58] Similarly, Corey Corcoran etches elaborate, nature-inspired motifs into the surface, highlighting the mushroom's organic contrasts in portfolio exhibitions.^[59] These applications demonstrate the enduring appeal of Ganoderma applanatum as an accessible, eco-friendly art form.^[56]

Medicinal applications

Ganoderma applanatum has been utilized in traditional medicine across various cultures, particularly in East Asia and among Native American communities. In Traditional Chinese Medicine, it serves as a cooling tonic to resolve internal heat conditions such as headaches and insomnia, while its bitter and mildly sweet properties support digestion and nourish vitality through decoctions prepared as teas.^[60] Native American traditions employ decoctions of the fungus for healing respiratory ailments, enhancing immune function, and acting as a diuretic, often in ceremonial and protective rites.^[61] Additionally, powdered forms have been applied topically as poultices to promote wound healing due to its antiseptic qualities.^[62] In modern applications, extracts of Ganoderma applanatum are incorporated into supplements primarily for immune support and as adjuncts in cancer therapy. Polysaccharides and triterpenes in the fungus stimulate immune responses by activating macrophages and promoting cytokine production, positioning it as a potential immunomodulator.^[62] Preclinical studies demonstrate its anti-cancer potential, with methanolic extracts inducing apoptosis in colon cancer cells via p53-independent pathways in vitro (IC50 of 160 μg/ml) and reducing tumor volume in mouse models through p53-dependent mechanisms, suggesting utility as a complementary agent.^[63] As of 2025, further research has explored its extract as an anticancer and immunomodulator in diethylnitrosamine-induced colon cancer models in rats, showing reduced tumor incidence and improved immune parameters.^[64] In silico studies have also indicated potential antiviral activity against SARS-CoV-2.^[65] Common forms include powders (1-3 grams daily, often encapsulated), tinctures (20-30 drops twice daily via dual alcohol-water extraction), and teas (simmered decoctions of 1-2 teaspoons per cup for 1-2 hours).^[66] Safety profiles indicate Ganoderma applanatum is generally non-toxic when used appropriately, with rare side effects such as nausea or digestive upset reported in sensitive individuals.^[62] However, potential allergic reactions, including rashes or respiratory issues, may occur in those with mushroom sensitivities, and caution is advised for individuals with autoimmune conditions or on anticoagulants due to its immune-modulating and blood-thinning effects.^[62] Recent nutritional analyses from 2024 highlight its integration into dietary practices, revealing high protein (21.01 ± 0.88%) and carbohydrate (33.63 ± 0.66%) contents on a dry weight basis, supporting its role in vitality-enhancing supplements.^[67] These benefits align briefly with its pharmacological properties as an antioxidant and anti-inflammatory agent.^[67]

Other uses

_Ganoderma applanatum has been explored for industrial applications, particularly in natural dye production. Pigments extracted from its fruiting bodies yield a rusty dye, which produces rust-colored hues on fabrics when using ammonia as a mordant, offering an eco-friendly alternative to synthetic dyes for wool and other fibers.^[68] Additionally, its ligninolytic enzymes enable significant degradation of wood waste; in submerged fermentation, it achieves up to 40.9% lignin removal from oak sawdust, alongside 32.7% hemicellulose and 27.4% cellulose breakdown, highlighting its potential in bioremediation to enhance wood residue digestibility for applications like bioethanol production and animal feed.^[69] Although primarily known for other purposes, G. applanatum is considered an edible mushroom in certain contexts, particularly when young, though its mature woody texture renders it largely unsuitable for direct culinary consumption and it is often avoided due to toughness.^[70] Recent proximate analyses reveal its nutritional profile, with fruiting bodies containing 30.72–41.80% carbohydrates, 11.10–11.56% protein, 14.49–16.18% crude fiber, 0.50–0.54% fat, 2.30–2.51% ash, and 42.67–54.67% moisture, positioning it as a potential supplementary source for proteins, fibers, and minerals in diets.^[71] In ornamental and educational settings, G. applanatum serves as a specimen in mycology displays and botanical gardens, valued for its distinctive shelf-like form to illustrate fungal morphology and wood decay processes.^[72]^[73]
