The thorny goatee ( Hericium cirrhatum , Syn . : Creolophus cirrhatus ) is a type of mushroom from the family of goatee relatives .
features
The fruiting body consists of hat-like, flat and sessile elements that have grown together like tufts. The individual hats are 50 to 150 millimeters wide and creamy white when young, later yellowish to yellowish brown in color. They are usually irregularly lobed and often bent or twisted. Their top is covered with thorn-like short spines that do not follow any particular direction. The close-up spines on the underside of the hats with the spore-bearing fruit layer, however, are arranged vertically. The whitish flesh, tender in the young fruiting body, turns yellow and becomes somewhat tough with age. The spore powder of the thorny goatee is white.
The spores are broadly ellipsoidal to almost spherical, smooth, amyloid and measure 3 to 4 × 2.5 to 3.5 micrometers. They do not have a germ pore.
Species delimitation
The thorny goatee differs from the other species of its genus by its hat-shaped fruiting bodies. The hedgehog barbed beard does not form hats, but rather dense clusters of hanging spines on a common trunk.
Species of the genus Climacodon are also similar . The fruiting bodies are flatter with very dense spines. Their top is rough or hairy, but not prickly. They have a more regular, rounded brim, especially when they are young. Especially with the northern barbed oyster ( Climacodon septentrionalis ) the hats are often arranged in a densely fan-shaped manner.
Ecology and phenology
The thorny goatee grows from August to November on the rotten wood of dead deciduous trees. It occurs on beech , birch and oak . The saprophytic fungus produces white rot on its substrate .
meaning
The thorny goatee is edible when young. Due to its rarity (Red List G3), the species should be spared.
