Botryobasidium parvisetosum is a mushroom species from the family of grape basidia relatives (Botryobasidiaceae). It forms resupinate, cobweb-like fruit bodies thatgrowon dead wood of pines . The known distribution area of Botryobasidium parvisetosum includes the Mascarene island of Réunion . The anamorphic of the species is not yet known.
features
Macroscopic features
Botryobasidium parvisetosum 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 parvisetosum is monomitic, i.e. it consists exclusively of generative hyphae that branch out at right angles. The basal hyphae are hyaline , usually 6–7 µm wide, thick-walled and not encrusted. The 4–6 µm thick subhymenial hyphae are hyaline and thin-walled. Unlike almost all grape basidia, the species has both 36–70 × 6–6.5 µm large, basal thickened cystids and buckles on all septa. The six-pore basidia of the species grow in nests, are 8.5–11 × 6–7 µm in size, are short-cylindrical and buckled at the base. The spores are very variable from spindle to boomerang-shaped and 1.9–9 µm in size. They are hyaline, smooth and thin-walled and have an appendage.
distribution
The known distribution of Botryobasidium parvisetosum only includes the Mascarene island of Réunion in the Indian Ocean .
ecology
Botryobasidium parvisetosum is a saprobiont that grows on white rotten dead wood . A well-known substrate is the crescent fir ( Cryptomeria japonica ).
