Botryobasidium subalbidum is a mushroom species from the family of grape basidia relatives (Botryobasidiaceae). It forms resupinate, cobweb-like fruiting bodies thatgrowon stem porlings. The range of Botryobasidium subalbidum includes the New York Adirondack Mountains . An anamorph of the species is not yet known.
features
Macroscopic features
Botryobasidium subalbidum has dirty gray-white, spider-like and thin fruiting bodies that grow resupinate (i.e. completely adjacent) on their substrate and appear slightly reticulate under the magnifying glass.
Microscopic features
As with all grape basidia , the hyphae structure of Botryobasidium subalbidum is monomitic, i.e. it consists exclusively of generative hyphae that branch out at right angles. The basal hyphae are light yellow, mostly 8–11 × 30–80 µm in size, thick-walled and not encrusted. The 5–8 µm thick subhymenial hyphae are almost hyaline and thin-walled. Like almost all grape basidia, the species has neither cystides nor buckles . The four- to six-pore basidia of the species grow in nests, are 20 × 7–8 µm in size, are approximately cylindrical in shape and slightly waisted in the middle. The spores are broadly ovate to broadly ellipsoidal and usually 6–6.4 × 4–6.5 µm in size. They are hyaline and thin-walled and have a distinct appendage.
distribution
The known distribution of Botryobasidium subalbidum so far only includes the type locality in the New York Adirondack Mountains .
ecology
Botryobasidium subalbidum is a saprobiont that colonizes other types of fungus. So far it has only been found on the fruit layer of old Irpex lacteus fruit bodies, which in turn settled on dead deciduous tree branches.
