The tar-Drüsling ( Exidia pithya ) is a fungal art of tremellomycetes from the family of the ear flap mushroom relatives (Auriculariaceae). Its pitch-black, gelatinous, wrinkled fruit bodies grow in dense, merging groups. They appear throughout the year on rotten dead wood of conifers . The species is distributed throughout the temperate Palearctic .
features
Macroscopic features
The tar spot glandular forms cartilaginous-gelatinous fruiting bodies. Your overlying hymenium is flat wavy to ribbed. The basidiocarpies have a slightly narrowed base, the top has a tar-black sheen. The initially spherical or wart-shaped basidiocarpies grow gregarious and dense and merge into a black, 4 mm thick carpet with a wrinkled surface and a notched edge. The species differs from the warty glandular ( E. plana ) by its smaller growth and fewer glandular warts on the surface.
Microscopic features
The hyphae structure of the tar-spot glandular is monomitic like all glandular ones , so it consists only of generative hyphae. They are cylindrical, hyaline, and inamyloid . The sterigmata are 30 microns shorter than in the warty Drüsling.
distribution
The tar-spot glandle inhabits a Palearctic species area that extends from France to the Altai . The species prefers submeridional and temperate climates . In the south of the area it inhabits the colder mountains, in the north it is more likely to be found in the plains.
ecology
Like other glands, the tar-spot gland is a saprobiont . It colonizes dead wood from conifers, but especially from Norway spruce ( Picea abies ) and silver fir ( Abies alba ), as well as various pines ( Pinus spp.). The fructification takes place all year round.
