14 Unique Mushrooms From Trees​

1. Lion’s Mane (Hericium erinaceus)

Lion’s Mane is one of the most visually striking tree-growing fungi, recognized by its cascading spines that resemble delicate icicles or the flowing mane of a white lion. The fruiting body forms a rounded mass, typically 10–25 cm across, though older clusters may reach larger dimensions. Each spine measures up to 4 cm long and hangs downward in dense curtains. Its texture is soft when young but becomes brittle as it matures. The color starts pure white, gradually shifting to yellowish or light brown with age or sun exposure.

This species forms predominantly on dead or dying hardwoods, especially oak, beech, and maple. It usually appears from late summer to early winter, depending on climate. Lion’s Mane is non-toxic and widely appreciated as an edible fungus with seafood-like flavor and medicinal value. It contains bioactive compounds believed to support cognitive health, nerve growth, and immune balance.

Ecologically, it helps break down lignin and cellulose, speeding the decomposition process in mature forests. For foragers, it is one of the safest mushrooms from trees​, thanks to its distinctive appearance, limited look-alikes, and lack of toxic species within the genus. Its presence often indicates advanced decay stages in hardwood trees.

2. Turkey Tail (Trametes versicolor)

Turkey Tail is a thin, polypore mushroom shaped like overlapping fans or semicircular shelves. Each cap measures 2–8 cm wide and displays vividly colored concentric zones in shades of brown, blue, gray, tan, rust, or cream. The velvety surface and the presence of many narrow bands distinguish it from other bracket fungi. Its underside consists of tiny white pores rather than gills, allowing efficient spore dispersal.

This species thrives on decomposing logs, fallen branches, and hardwood stumps, making it one of the most widespread mushrooms that grow on trees worldwide. It fruits year-round in many regions, though fresh growth is most visible in autumn. Turkey Tail is not poisonous; in fact, it is valued in medicine for its polysaccharopeptides (PSP and PSK), which may support immune health and have been studied in cancer therapy contexts.

Ecologically, this fungus plays a critical role as a primary decomposer of lignin, aiding nutrient cycling and forest regeneration. Its ability to colonize a wide range of tree species—such as oak, birch, willow, and beech—makes it incredibly adaptable. Although not typically eaten as food due to its tough texture, it is commonly brewed into teas and extracts. Its resilience and bright coloration make it one of the easiest wood-inhabiting mushrooms to identify.

3. Chicken of the Woods (Laetiporus sulphureus)

Chicken of the Woods forms large, overlapping rosettes of thick, fan-shaped caps. Individual shelves may reach 20–30 cm across, and entire clusters can weigh several kilograms. The caps are bright sulfur-yellow or orange, with smooth surfaces that develop wavy, lobed edges. its underside is covered with sulfur-colored pores rather than gills. Younger specimens are soft and juicy, while older caps become woody.

This species grows primarily on oak, cherry, yew, and chestnut. It appears from late spring through early autumn. Chicken of the Woods is considered edible but must be cooked thoroughly. However, a minority of people experience stomach upset, especially when consuming specimens from conifers or eucalyptus. Thus, proper identification and harvesting from safe hosts are crucial.

Ecologically, this fungus is a brown-rot decomposer, breaking down cellulose and leaving behind crumbly brown lignin. It weakens trees significantly and can be a destructive parasite on living hardwoods. Despite this, its striking coloration and large size make it one of the most recognizable mushrooms from trees​. When safely harvested, it offers excellent culinary value, often compared to chicken meat in flavor and texture. It also provides habitat for insects that rely on decaying wood.

It also provides shelter for small insects under its tough cap. The combination of health benefits and its distinctive glossy look makes Reishi one of the most culturally significant tree-borne fungi.

5. Oyster Mushroom (Pleurotus ostreatus)

Oyster mushrooms feature smooth, shell-like caps 5–20 cm wide, colored white, gray, tan, or light brown depending on age and environment. The caps are gently curved with wavy edges, and the gills run down the short, off-center stem. Their texture is soft and fleshy when young but becomes tough as they mature. A faint anise-like aroma is often noticeable.

This species grows in clusters on dead or dying hardwoods such as beech, poplar, and willow. It appears mainly in autumn, though mild climates can produce fruiting year-round. Oyster mushrooms are edible, safe, and widely cultivated for culinary use. They contain compounds like lovastatin, which may support heart health, and are rich in protein and antioxidants.

Oyster mushrooms function as saprophytes, decomposing wood and returning nutrients to the soil. They also possess carnivorous tendencies, capturing nematodes through toxin-releasing structures. This unique adaptation provides extra nitrogen, aiding their growth on nutrient-poor wood. Their broad availability, mild taste, and ease of identification make them one of the most accessible mushrooms from trees​ for beginners and experts alike.

6. Chaga (Inonotus obliquus)

Chaga is one of the most unusual tree-borne fungi, forming a dense, charcoal-black mass rather than a typical mushroom cap. The outer crust looks like burnt wood with deep cracks, while the interior is a rich orange-brown color. A typical growth ranges from 10–38 cm wide and can weigh several kilograms, depending on how long it has been developing. Unlike many mushrooms from trees​, the true fruiting body of Chaga forms inside the bark; the black conk seen externally is a sterile structure.

Chaga grows almost exclusively on birch trees in cold northern climates across Russia, Canada, and Scandinavia. It requires years—sometimes decades—to mature. This fungus appears year-round, as it persists through winter and summer alike. Chaga is non-toxic and widely consumed in the form of tea, extracts, or powdered supplements. It contains high levels of antioxidants, betulinic acid, and polysaccharides, which are studied for immune-modulating properties.

Ecologically, Chaga acts as both parasite and decomposer. It weakens birch trees slowly, often leading to decay, but also contributes to forest nutrient recycling once the tree collapses. Though not a culinary mushroom due to its hard texture, Chaga remains one of the most iconic mushrooms that grow on trees, valued for both cultural and medicinal significance.

7. Artist’s Conk (Ganoderma applanatum)

Artist’s Conk is a large, perennial fungus recognized by its thick, hoof-shaped brackets. Individual caps may reach 30–60 cm across and several centimeters thick. The upper surface is grayish-brown with a hard, woody texture, while the underside displays a smooth white pore layer that stains dark brown when scratched—hence the name “artist’s conk,” as people use it as a natural canvas. It is one of the most durable wood-growing mushrooms, often persisting for many years on the same tree.

This species typically grows on dead hardwoods such as maple, poplar, and oak, although it may also appear on weakened living trees. It fruits from late spring through autumn, but its tough structure remains visible year-round. Artist’s Conk is not edible because of its dense texture, yet it has been used in traditional medicine and natural artwork.

Ecologically, it plays a vital role as a decomposer of lignin and cellulose, accelerating the breakdown of old trees. It creates microhabitats for insects and provides shelter for small arthropods.

Honey Fungus forms clusters of honey-colored caps, each 3–15 cm wide, with smooth or slightly scaly surfaces. The caps are typically golden brown, fading toward the edges. Their stems are long, tough, and feature a distinctive white ring near the top. At night, the mycelium of this species can exhibit a faint greenish bioluminescence known as “foxfire.” This characteristic makes Honey Fungus one of the most intriguing tree-attached mushrooms in temperate forests.

Unlike many mushrooms from trees​ that are strictly decomposers, Honey Fungus is a powerful parasite capable of attacking living trees. It infects roots, eventually killing the host before colonizing the dead wood. Armillaria species are responsible for some of the largest living organisms on Earth due to their massive underground networks. This fungus fruits in autumn, often after heavy rain.

While edible when cooked thoroughly, Honey Fungus can cause stomach upset in some individuals, so caution is advised. Ecologically, it plays a dual role: destructive parasite on the one hand, but efficient decomposer on the other. Its rhizomorphs—dark, bootlace-like strands—spread through soil and help recycle nutrients once trees die. Its combination of beauty, danger, and biological complexity makes it one of the most discussed mushrooms that grow on trees.

13. Tinder Conk / Hoof Fungus (Fomes fomentarius)

Tinder Conk, also known as Hoof Fungus due to its hoof-like shape, is a large, perennial bracket mushroom commonly found on birch, beech, and maple. Its hard, woody fruiting body ranges from 10–40 cm across and develops multiple growth layers over the years. The upper surface is smooth and gray with curved contour lines, giving it the appearance of an animal hoof. Underneath, the pore layer is light brown and extremely dense.

Historically, this wood-inhabiting fungus has been used to create fire-starting tinder, earning its name. Its fibrous interior can be processed into “amadou,” a felt-like material used historically for clothing patches and even hat-making. It is non-toxic but inedible due to its very tough structure.

Tinder Conk grows mainly in cool climates and fruits year-round. It often colonizes weakened birch trees but can persist long after the host dies. Ecologically, it is a major force in white-rot decay, breaking down tough lignin and helping return cellulose to the forest soil. As one of the most enduring mushrooms from trees​, it can remain attached for decades, gradually expanding its size. It also provides microhabitats for beetles, fungi-loving insects, and small invertebrates, playing an integral role in forest decomposition cycles.

14. Jack-o’-Lantern (Omphalotus illudens)

Jack-o’-Lantern mushrooms are one of the most striking tree-growing fungi, known for their bright orange caps and eerie bioluminescent gills that glow faintly in the dark. The caps are typically 5–20 cm wide, with smooth, slightly depressed centers and decurrent gills that run down the stem. Their vivid orange coloration makes them easy to spot at the base of hardwood stumps, buried roots, or decaying logs.

Despite their appealing appearance, Jack-o’-Lanterns are toxic and must never be eaten. They contain illudin compounds that cause severe gastrointestinal distress. Their glowing effect, visible in complete darkness, results from a chemical reaction called luciferin–luciferase bioluminescence.

This species appears in summer and autumn, often after prolonged moisture. It commonly fruits in dense clumps on oak, beech, and other hardwood species. Ecologically, Jack-o’-Lanterns act as saprophytic decomposers, aiding in the breakdown of dead wood. They are sometimes mistaken for edible chanterelles, but their growth on wood, true gills, and bioluminescence distinguish them clearly.

As one of the most visually dramatic mushrooms that grow on trees, the Jack-o’-Lantern contributes to forest ecology while reminding foragers of the importance of careful identification. Its unique glow also supports scientific studies on fungal light production.
