Botryobasidium pilosellum is a mushroom species from the family of grape basidia relatives (Botryobasidiaceae). It forms resupinate, cobweb-like fruiting bodies thatgrowon the dead wood of conifers . The distribution area of Botryobasidium pilosellum is in Ukraine . An anamorph of the species is only known from cultures.
features
Macroscopic features
Botryobasidium pilosellum has gray to whitish, spinel-like and thin fruit bodies, which 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 pilosellum is monomitic, i.e. it consists exclusively of generative hyphae that branch out at right angles. The basal hyphae are usually 6–8 µm wide, slightly thick-walled and encrusted. The 4–6 µm thick subhymenial hyphae are hyaline , covered with crystals and thin-walled. Unlike most grape basidia, the species has encrusted cystids 65–100 × 4–9 µm in size and buckles on all septa . The six- to eight-pore basidia of the species grow in nests, are 15–20 × 5–6.5 µm in size and are constricted-headed. The spores are shaped like boats, 5–6 × 2.5–3 µm in size, hyaline, smooth and thin-walled.
distribution
The known distribution area of Botryobasidium pilosellum includes the Ukraine .
ecology
Botryobasidium pilosellum is a saprobiont that grows on the rotten dead wood of conifers . The substrates of the species have not yet been identified.
