Athelia pycophila is a stand mushroom art from the family of the tissue skin relatives (Atheliaceae). It forms resupinate, whitish and moldy carpet-like fruiting bodies on deciduous mosses . The known distribution of the species is limited to Venezuela . With a blue alga of the genus Scytonema , it forms lichens .
features
Macroscopic features
Athelia pycophila forms like all species from the genus of the tissue skin ( Athelia ) 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 pycophila has a monomitic hyphae structure that is typical for tissue membranes , that is, it only has generative hyphae , which are used for the growth of the fruiting body. The hyphae are hyaline and thin-walled to slightly thick-walled at the base. They have no buckles and are 4–5 µm wide. The species does not have cystidia . Their basidia are hyaline, 13–16 × 5.5–6.5 µm in size and shaped like a club. At the base they are simply septate, they have four sterigmata . The spores of the fungus are pear-shaped, 5–6.5 × 3.5–4.2 µm in size, smooth and thin-walled, and hyaline. Often they stick together.
distribution
The known distribution of Athelia pycophila only includes the type locality in the Venezuelan Andes near Merida .
ecology
Athelia pycophila is a saprobiont that attacks the moss , probably the genus Polytrichum . It forms lichens with a species of blue algae belonging to the genus Scytonema .
