Botryobasidium botryoideum is a mushroom species from the family of grape basidia relatives (Botryobasidiaceae). It forms resupinate, cobweb-like fruiting bodies thatgrowon deciduous trees. The distribution area of Botryobasidium botryoideum includes a Holarctic area. An anamorph of the species is not yet known.
features
Macroscopic features
Botryobasidium botryoideum has grayish-white, old 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 botryoideum is monomitic, i.e. it consists exclusively of generative hyphae that branch out at right angles. The basal hyphae are light yellow, mostly 8–20 µm wide, thick-walled and not encrusted. The 6–9 µm thick subhymenial hyphae are almost hyaline and thin-walled. Like almost all grape basidia, the species has neither cystides nor buckles . The six- to rarely seven-pore basidia of the species grow in nests, are 18-25 × 7-8.5 µm in size, are approximately cylindrical in shape and slightly waisted in the middle. The spores are approximately spherical and mostly 4–5.5 × 3–5.5 µm in size. They are hyaline, smooth, and thin-walled.
distribution
The known distribution of Botryobasidium botryoideum includes Europe and North America in a Holarctic area.
ecology
Botryobasidium botryoideum is a saprobiont that grows on the dead wood of deciduous trees . Known substrates include English oak ( Quercus robur ) and wrinkled oak ( Alnus incana var. Rugosa ).
