Athelia coprophila is a stand mushroom art from the family of the tissue skin relatives (Atheliaceae). It forms resupinate, white and moldy carpet-like fruiting bodies on the bark of deciduous trees , rotten straw or cattle dung. The species inhabits a Holarctic areawith northern Europe and North Americaand is considered rare everywhere.
features
Macroscopic features
Athelia coprophila , like all types of tissue membranes ( Athelia ), forms cream-colored, thin fruiting bodies with a smooth hymenium and inconspicuous to spider-like edges. They can be easily removed from the substrate.
Microscopic features
Athelia coprophila 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 and thin to basal and slightly thick-walled. The subicular hyphae almost never have buckles , but the subhymenial hyphae often have them. Both are 4–5 µm wide and mostly branched at right angles. The species does not have cystidia . Their basidia are long club-shaped, 20–25 × 6–7.5 µm in size and usually grow in nests at the ends of the carrier hyphae. They are always buckled up at the base, they have four, rarely two, sterigmata . The spores of the fungus are spherical to broadly ellipsoidal, 4.5–6.5 × 4–6 µm in size, smooth and thin-walled and hyaline. They have a clear apiculus and are partly covered with oil droplets.
distribution
The known distribution of Athelia coprophila includes northern Europe ( Germany , Sweden , British Isles ) as well as Canada and the USA . The species is considered rare everywhere.
ecology
Athelia coprophila is a saprobiont that colonizes decaying plant remains. The species can be found on hardwood bark , rotten straw , grasses or on cattle manure , among other things .
