Botryobasidium lacinisporum is a mushroom species from the family of grape basidia relatives (Botryobasidiaceae). It forms resupinate, cobweb-like fruiting bodies thatgrowon the dead wood of maples . The distribution area of Botryobasidium lacinisporum includes the south of Canada . No anamorph of the species is known.
features
Macroscopic features
Botryobasidium lacinisporum has 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 lacinisporum is monomitic, i.e. it consists exclusively of generative hyphae that branch out at right angles. The basal hyphae are light yellowish, usually 5–8 µm wide, thick-walled and not encrusted. The 5–8 µm thick subhymenial hyphae are hyaline and thin-walled. Like almost all grape basidia, the species does not have cystids or buckles . The six-pore basidia of the species grow in nests, are 13-16 × 7-8 µm in size and are constricted in the middle. The spores are irregularly shaped, but always have three tips, which gives them a tetrahedral appearance. They are usually 3–5 × 2.5–4 µm in size, hyaline, smooth and thin-walled.
distribution
The known distribution area of Botryobasidium lacinisporum only includes the Canadian Ontario .
ecology
Botryobasidium lacinisporum is a saprobiont that grows on the rotten dead wood of maples ( Acer spp.).
