Donk 1962

The tooth membranes ( Dentipellis ) form a genus of fungi within the family of the goatee relatives (Hericiaceae). The resupinate , membranous, thin fruiting bodies are covered with long spines or teeth. The subiculum is thin but clearly developed. The fungi have gloeoplere hyphae and amyloid , warty to prickly spores. There are around 10 species worldwide. The type of the genus is Dentipellis fragilis (Pers.: Fr.) Donk.

features

The annual, resupinate membranous, whitish fruit bodies cover the substrate with a thin membrane. The hymenophore consists of long, rounded spines or flattened teeth. The meat is soft, dry and quite fragile. The spore powder is whitish. The almost spherical to ellipsoidal, thin-walled, 4.5–6 µm long and 4–5 µm wide, amyloid spores are decorated with warty or prickly ornamentation . The narrow-clumped, 2- to 4-spore basidia are 20–35 µm long. In addition, one can find gloeocystids. The hyphae system is monomitic , the hyphae wear buckles on the septa .

Ecology and diffusion

The fungi live saprobion table on hardwood (mostly red beech ) and cause white rot on the affected wood . In Europe there is only one species, the tender prickly bark fungus ( Dentipellis fragilis ), which grows on the underside of rotten, lying trunks, but also on tree stumps.

Systematics

The genus Dentipellis was proposed in 1982 by MA Donk in order to separate Hericium fragile and other species from the genus Hericium .

Minimum Evolution pedigree from Dentipellis . Dentipellis is closely related to Laxitextum and Hericium of the Hericiaceae type genus. The family tree was created using the MEGA 5.10 program. All rDNA sequences come from GenBank . The bootstrap test was carried out with 1000 repetitions. All further information is given in the image description.

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

The name is derived from the Latin nouns "dens" (tooth) and "pellis" (skin).

meaning

Edible mushrooms do not belong to the genus.
