Athelia macrospora 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 , but also on other mushrooms. The known distribution of the species includes the northern regions of the Holarctic .
features
Macroscopic features
Athelia macrospora , like all types of tissue membranes ( Athelia ), forms white to cream-colored, thin (dry cracked) fruit bodies with a smooth hymenium and inconspicuous to spider-like edges. They can be easily removed from the substrate.
Microscopic features
Athelia macrospora has a monomitic hyphae structure 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, basal slightly thick-walled. The subicular hyphae have occasional buckles , the subhymenial hyphae are simply septate. Both are 5–7 µm wide and mostly branched at right angles. The species does not have cystidia . Your basidia are long cylindrical-clavate to club-shaped, 20–36 × 8–10 µm in size and grow in nests. At the base they are simply septate, they have four sterigmata . The spores of the fungus are long ellipsoidal, 9–13.5 × 5–6.5 µm in size, smooth and thin-walled, and hyaline. They have a not always clear apiculus.
distribution
The known distribution of Athelia macrospora includes central and northern Europe as well as New Jersey in the United States .
ecology
Athelia macrospora is a saprobiont that attacks conifers and flowering plants , but also fungi. Well-known host species include common beech ( Fagus sylvatica ) and Nordmann fir ( Abies nordmanniana ) as well as fungi of the genus Vuilleminia .
