Athelia andina 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 earth and stones. 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 andina forms like all species from the genus of the tissue skin ( Athelia ) whitish to yellow-colored, thin fruiting bodies with 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 andina 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-walled. They have no buckles and are 3.5–6 µm wide. The species does not have cystidia . Their basidia are hyaline, 10–17 × 6–8 µm in size and broad-cylindrical to club-like in shape. At the base they are simply septate, they have four sterigmata . The spores of the fungus are broadly elliptical in shape, 6.5–7.5 × 4.5–4.8 µm in size, smooth and thin-walled and hyaline. Basal they are slightly wider than apical, they have a distinct extension.
distribution
The known distribution of Athelia andina only includes the area around the type locality in the Venezuelan Andes near Merida .
ecology
Athelia pycophila develops its fruiting bodies on earth and stones. It forms lichens with a filamentous blue-green algae of the genus Scytonema .
