Botryobasidium vagum is a mushroom species from the family of grape basidia relatives (Botryobasidiaceae). It forms resupinate, cobweb-like fruit bodies thatgrowon the dead wood of deciduous and coniferous trees. Botryobasidium vagum is common in Europe and North America and is considered a common species.
features
Macroscopic features
Botryobasidium vagum has whitish to ocher-colored, spider-like fruit bodies, which 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 vagum is monomitic , i.e. it consists only of generative hyphae that branch out at right angles. The basal hyphae are hyaline , narrow (mostly 7–10 µm wide) and not encrusted. The 5–7 µm thick subhymenial hyphae are hyaline , short-celled, thin-walled and cyanophilic. The species does not have cystids or buckles . The six-pore basidia of the species grow in nests, are 20–25 × 8–12 µm in size, are sub-cylindrical to club-shaped and simply septate at the base. The spores are narrow, boat-shaped and mostly 8–12 × 4.5–6 µm in size. They are smooth and thin-walled.
distribution
The known distribution of Botryobasidium vagum covers a Holarctic area with Europe and North America . The species is thought to be widespread and common.
ecology
Botryobasidium vagum is a saprobiont that colonizes dead wood . They were found on black pines ( Pinus nigra ), Norway spruces ( Picea abies ), downy oak ( Quercus pubescens ) and European beech ( Fagus sylvatica ).
