Botryobasidium grandisporum 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 range of Botryobasidium grandisporum includes Taiwan . No anamorph of the species is known.
features
Macroscopic features
Botryobasidium grandisporum 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 grandisporum is monomitic, i.e. it consists exclusively of generative hyphae that branch out at right angles. The basal hyphae are yellowish, usually 6–10 µm wide, thick-walled and not encrusted. The 6–10 µm thick subhymenial hyphae are hyaline and thin-walled. Like almost all grape basidia, the species does not have cystides , but has buckles on the many subhymenial septa. The six-pore basidia of the species grow in nests, are 35–40 × 10–12 µm in size and approximately urn-shaped. The spores are wide, boat-shaped and mostly 12–15 × 6–7 µm in size. They are hyaline, smooth, and thin-walled.
distribution
The known distribution area of Botryobasidium grandisporum only includes Taiwan .
ecology
Botryobasidium grandisporum is a saprobiont that grows on the rotten dead wood of conifers . The substrates have not yet been determined more precisely.
