features
Macroscopic features
Athelia tenuispora forms like all species from the genus of the tissue skin ( Athelia ) whitish to cream-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 tenuispora 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-walled to slightly thick-walled at the base. They only occasionally have buckles on the basal side and are 4–7 µm wide and branched at right angles. The species does not have cystidia . Their basidia are hyaline, broadly club-shaped, 16–18 × 6.5–7.5 µm in size and grow in tufts. At the base they are simply septate, they have four, rarely two, sterigmata . The spores of the fungus are elongated, ellipsoidal, 8–10 × 3.5–4 µm in size, smooth and thin-walled and hyaline. They have a distinct extension.
distribution
The known distribution of Athelia tenuispora includes northern Europe, the former USSR , Canada, and the United States in large parts of the Holarctic .
ecology
Athelia tenuispora is a saprobiont that attacks conifers and deciduous trees . Substrates include balsam fir ( Abies balsamea ), silver birch ( Betula pendula ) and willow ( Salix caprea ).
