Athelia subovata is a stand mushroom art from the family of the tissue skin relatives (Atheliaceae). It forms resupinate, whitish and membrane-like fruiting bodies on conifers , mosses and coversamers . The known distribution of the species is limited to Sweden .
features
Macroscopic features
Athelia subovata , like all types of tissue membranes ( Athelia ), forms thin fruiting bodies with a smooth hymenium and thinning edges. They are whitish and can be easily removed from the substrate.
Microscopic features
Athelia subovata has a monomitic hyphae structure that is 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 slightly thick-walled. The subicular hyphae often have buckles , the subhymenial hyphae, however, are always simply septate, both are 4–5 µm wide and partly covered with crystals. The species does not have cystidia . Their basidia are broad, cylindrical to club-shaped, 13–19 × 4.5–5.5 µm in size. At the base they are simply septate, they have four sterigmata and grow in tufts on the carrier hyphae. The spores of the fungus are narrow, egg-shaped, 6.5–75 × 2.5–3.2 µm in size, smooth and thin-walled and hyaline. They have a small but distinct lateral extension.
distribution
The known distribution of Athelia subovata only includes the region around the type locality in the Swedish Ångermanland .
ecology
Athelia subovata is a saprobiont that attacks dead wood from conifers and flowering plants. Well-known host species are Norway spruce ( Picea abies ) and aspen ( Populus tremula ).
