features
Macroscopic features
Athelia rolfsii , like all types of tissue membranes ( Athelia ), forms thin fruiting bodies with a smooth hymenium and thinning edges. They are colored white and can easily be removed from the substrate.
Microscopic features
Athelia rolfsii has a monomitic hyphae structure that is typical for tissue membranes , that is, it only has generative hyphae , which serve the growth of the fruiting body. The hyphae are hyaline and thin to slightly thick-walled. They often have buckles and are 5.6–8.6 µm wide. The species does not have cystidia . Their basidia are approximately cylindrical to club-shaped and 6–11 × 4–5.6 µm in size. At the base they are partly septate, partly buckled. They have two to four sterigmata . The spores of the fungus are ovate to broadly ellipsoid in shape, 4–7 × 3–5 µm in size, smooth and thin-walled and hyaline. They are rounded on the top and pointed on the underside.
distribution
The known distribution of Athelia rolfsii includes the tropics of the old and the new world, as well as large parts of the Ne and Palearctic . It is especially common in warm climates.
ecology
Athelia rolfsii is a saprobiont that attacks vegetables and grains . The host plants include tomatoes ( Solanum lycopersicum ) and soybeans ( Glycine max ).
