Athelia Alnicola is a stand mushroom art from the family of the tissue skin relatives (Atheliaceae). It forms resupinate, white and mold-like fruiting bodies on conifers and flowering seeds . The known distribution of the species includesa Holarctic areawith northern Europe and the USA .

features

Macroscopic features

Athelia alnicola , like all types of tissue membranes ( Athelia ), forms thin fruiting bodies with a smooth hymenium and inconspicuous to spider-like edges. They are white when young, later cream-colored to yellow-ocher and can be easily removed from the substrate.

Microscopic features

Athelia alnicola has a monomitic hyphae structure that is typical for 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 have occasional buckles , the subhymenial hyphae are simply septate, both are 5–7  µm wide. The species does not have cystidia . Their basidia are broadly cylindrical to club-shaped, 15-25 × 5-8 µm in size and cylindrical in shape. At the base they are simply septate, they have four sterigmata . The spores of the fungus are broadly ellipsoid in shape, 6.5–8.5 × 5–8 µm in size, smooth and thin-walled, and hyaline. They have a distinct extension and are often glued together in groups of four.

distribution

The well-known distribution of Athelia alnicola includes the USA, Germany , the Czech Republic and Sweden, a scattered area in the Holarctic .

ecology

Athelia alnicola is a saprobiont that attacks conifers and flowering plants. Well-known host species include Weymouth pine ( Pinus strobus ) and gray alder ( Alnus incana ).
