Dentipellis

The type species of the genus Dentipellis fragilis.

The tooth skins ( Dentipellis ) form a fungal genus within the family of spiky beard relatives ( Hericiaceae ). The resupinaten, membranous thin fruiting bodies are covered with long spines or teeth. The subiculum is thin, but clearly developed. The fungi have hyphae gloeoplere and amyloid warty to spiny spores. Worldwide there are about 10 species. The type species of the genus is Dentipellis fragilis (Pers.: Fr ) Donk.

Features

The one-year, resupinat - membranous, whitish fruit bodies cover the substrate membranous thin. The hymenophore consists of long, rounded spines or flattened teeth. The flesh is soft, dry and quite fragile. The spore powder is whitish. The nearly spherical to ellipsoidal, thin-walled, 4.5-6 microns long and 4-5 microns wide, amyloid spores are ornamented warty or prickly. The schmalkeuligen, 2 - to 4 - sporigen basidia are 20-35 microns long. In addition, one finds Gloeozystiden. The Hyphensystem is monomitisch at the septa bear the hyphae buckles.

Ecology and distribution

The fungi live saprobiontisch on Hardwood ( mostly beech ) and call on the infested wood a white rot out. In Europe, there is only one way to Hinterzarten palmetto fungus ( Dentipellis fragilis ) that grows on the underside of rotten, lying tribes, but also on tree stumps.

System

The genus was Dentipellis 1982 by M. A. Donk proposed to separate Hericium fragile and more species of the genus Hericium.

The genus Dentipellis is closely related to the two genera Laxitextum and Hericium. Unifying features are the prickly hymenophore, the occurrence of Gloeozystiden and ornamented amyloid spores. The relationship is also supported by molecular data ( Sequence comparison of the rDNA genes).

The name derives from the Latin noun " dens " (tooth) and " pellis " (skin).

Importance

The genus does not include edible mushrooms.
