Botryobasidium verrucisporum is a mushroom species from the family of grape basidia relatives (Botryobasidiaceae). It forms resupinate, cobweb-like fruiting bodies thatgrowon the dead wood of silver firs . Botryobasidium verrucisporum is only from the Sycamore Canyon in the US Arizona known.
features
Macroscopic features
Botryobasidium verrucisporum has light gray, spinel-like and thin fruiting bodies that grow resupinate (i.e. completely adjacent) on their substrate and appear slightly net-like under the magnifying glass.
Microscopic features
As with all grape basidia , the hyphae structure of Botryobasidium verrucisporum is monomitic, i.e. it consists exclusively of generative hyphae that branch out at right angles. The basal hyphae are light yellow to light brown, usually 5–8 µm wide and not encrusted. The subhymenial hyphae are loosely interwoven and thin-walled. All hyphae are simply septate. Like almost all grape basidia, the species has neither cystides nor buckles . The four-pore basidia of the species grow in nests, are 25-30 × 7.5-9 µm in size, are cylindrical in shape and slightly thickened at the base. The spores are broadly ellipsoidal to almost spherical and usually 6–8 × 5–5.5 µm in size. They are hyaline, thick-walled, cyanophilic, and warty.
distribution
The known distribution of Botryobasidium verrucisporum so far includes only the type locality in Sycamore Canyon of arizonensischen Atascosa Mountains .
ecology
Botryobasidium verrucisporum is a saprobiont that colonizes dead wood . So far it has only been found dead fruiting bodies of Arizona oaks ( Quercus arizonica ).
