basidiomycete mushroom belonging to the Fistulinaceae family. The mushroom is characterized by its fleshy, reddish-brown to dark brown cap that resembles raw meat. The cap can reach up to 25 cm in width and 3 cm in thickness, with a slightly wavy margin. The spore-bearing surface of Fistulina hepatica consists of numerous small tubes that can be up to 6 mm long. The tubes are initially white to cream in color, turning reddish-brown as the mushroom matures. The spores released by the Beefsteak Fungus are elliptical, measuring 5 to 7 µm in length and 3 to 4.5 µm in width. The stipe of Fistulina hepatica is short or sometimes absent, with a fibrous and fleshy texture. The mushroom's flesh is firm, fibrous, and moist, often exuding a reddish liquid when cut or pressed. This liquid is responsible for the mushroom's alternative name, "Ox Tongue." Fistulina hepatica grows primarily in the Northern Hemisphere, with a distribution that includes Europe, North America, and parts of Asia. The mushroom forms a parasitic relationship with various tree species, particularly oak and sweet chestnut trees. This parasitic interaction results in a form of white rot that can cause decay in the host tree. The fruiting period for Fistulina hepatica typically occurs from late summer to autumn. The mushroom is often found growing solitary or in small groups on the trunks of living trees or fallen logs. Fistulina hepatica is considered an edible mushroom, prized for its unique taste and texture. The mushroom has a slightly acidic, tangy flavor that is reminiscent of lemon or vinegar. When cooked, the Beefsteak Fungus has a texture similar to that of beef, making it a popular choice for vegetarian dishes. The chemical composition of Fistulina hepatica is not well understood, but it has been suggested that the mushroom may contain compounds with potential medicinal properties. These compounds may exhibit antioxidant and antimicrobial activities, among other health benefits.
