Athelia salicum is a stand mushroom art from the family of the tissue skin relatives (Atheliaceae). It forms resupinate, whitish and moldy carpet-like fruit bodies on wood, leaves, lichens and mushrooms . The known distribution of the species includesa Holarctic areawith Eurasia and North America .
features
Macroscopic features
Athelia salicum , like all species from the genus of the tissue skin ( Athelia ), forms whitish to yellowish, thin fruiting bodies with a smooth hymenium and inconspicuous to fibrous edges. They are resupinate, that is, they lie directly on the substrate, and can easily be removed from it.
Microscopic features
Athelia salicum has a monomitic hyphae structure typical of tissue membranes , that is, it only has generative hyphae that serve the growth of the fruiting body. The hyphae are hyaline , simply septate and thin-walled to slightly thick-walled at the base. They sometimes have buckles in the subiculum and are 3–8 µm wide. The species does not have cystidia . Their basidia are hyaline, 10–16 × 5.5–8 µm in size and cylindrical to club-like in shape. At the base they are simply septate , they have four, rarely two, sterigmata . The spores of the fungus are ellipsoid in shape, 6–7.5 × 3.5–4.5 µm in size, smooth and thin-walled, and hyaline. They have a distinct extension ( apiculus ).
distribution
The known distribution of Athelia salicum includes almost all of Europe , the territory of the former USSR as well as Canada and the USA . It is apparently missing in southern Europe.
ecology
Athelia salicum is a saprobiont that attacks conifers and deciduous trees , withered leaves, lichens and other fungi. Well-known substrates include balsam fir ( Abies balsamea ), trembling poplar ( Populus tremula ), Xanthoria spp. and tobacco-brown bristle discs ( Hymenochaete tabacina ).
