features
Macroscopic features
Athelia alutacea , like all species from the genus of the tissue skin ( Athelia ), forms light cream-colored, 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 alutacea has a monomitic hyphae structure typical of tissue membranes , that is, it only has generative hyphae that are used for the growth of the fruiting body. The hyphae are hyaline and thin-walled to slightly thick-walled. They often have buckles at the base , while they are simply septate in the hymenium and subhymenium, and are 3.5–4.5 µm wide and branched at right angles. The species does not have cystidia . Their basidia are cylindrical to approximately club-shaped, 18–24 × 6–7 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 cylindrical and pointed at the base, 9–11.5 × 3.5–4.8 µm in size, smooth and thin-walled and hyaline.
distribution
The known distribution of Athelia alutacea only includes the type locality of the species in the US state of New Jersey .
ecology
Athelia alutacea is a saprobiont that attacks conifers . It was found on the wood and the bark of an unspecified type of softwood.
