Athelia nivea is a stand mushroom art from the family of the tissue skin relatives (Atheliaceae). It forms resupinate, white and mold-like fruit bodies on conifers , mosses and bedecktsamern . The known distribution of the species includes central and northern Europe .

features

Macroscopic features

Athelia nivea , like all types of tissue membranes ( Athelia ), forms thin fruiting bodies with a smooth hymenium and thinning edges. They are snow-white to cream-colored and can be easily removed from the substrate.

Microscopic features

Athelia nivea 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 basal and slightly thick-walled. The subicular hyphae almost always have buckles , the subhymenial hyphae, on the other hand, are usually simply septate, both are 2.5–4  µm wide. The species does not have cystidia . Their basidia are broadly club-shaped and 15–18 × 5.5–6.5 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 broadly cylindrical to ellipsoid in shape, 6.5–8 × 4.3–5.2 µm in size, smooth and thin-walled, and hyaline. They have a distinct extension and are slightly flattened or dented adaxially.

distribution

The known distribution of Athelia nivea includes Sweden , Great Britain , Germany and the Czech Republic in central and northern Europe.

ecology

Athelia nivea is a saprobiont that attacks conifers , mosses and flowering plants. Well-known host species include black pine ( Pinus sylvestris ), red beech ( Fagus sylvatica ) or cypress sleep moss ( Hypnum cupressiforme ).
