Botryobasidium sordidulum is a mushroom species from the family of grape basidia relatives (Botryobasidiaceae). It forms resupinate, cobweb-like fruiting bodies thatgrowon dead wood . The distribution area of Botryobasidium sordidulum includes the Gabonese Cape Esterias .
features
Macroscopic features
Botryobasidium sordidulum has yellowish-white, spinel-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 sordidulum is monomitic, i.e. it consists exclusively of generative hyphae that branch out at right angles. The basal hyphae are yellow, usually 7–9 µm wide, thick-walled and not encrusted. The 5.5–7 µm thick subhymenial hyphae are almost hyaline and thin-walled. Like almost all grape basidia, the species has neither cystides nor buckles . The rarely six-, mostly eight-pore basidia of the species grow in nests, are 16–20 × 8.5–10 µm in size and are compressed. The spores are narrow boat-shaped and mostly 9.5–12 × 3.2–4 µm in size. They are hyaline, smooth, and thin-walled.
distribution
The known distribution of Botryobasidium sordidulum includes only the type locality on Gabonese Cape Esterias .
ecology
Botryobasidium sordidulum is a saprobiont that grows on the dead wood of. The previous substrates were not specified, it was a large branch of a tree.
Systematics
Botryobasidium sordidulum was first described in 1982 by Jean Boudin and Gérard Gilles , who considered the species to be relatives of B. vagum and B. danicum .
