features
Macroscopic features
Botryobasidium asperulum has whitish to yellowish, 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 asperulum is monomitic, i.e. it only consists of generative hyphae that branch out at right angles. The basal hyphae are hyaline , narrow (mostly 10–15 µm wide) and not encrusted. The 5–7 µm thick subhymenial hyphae are hyaline and thin-walled. All hyphae are simply septate. The species has neither cystids nor buckles . The four-, six- or eight-pore basidia of the species grow in nests, are 10–18 × 6–8 µm in size, are cylindrical and simply septate at the base. The spores are ellipsoidal and usually 5–6 × 3–4 µm in size. They are finely coated and thin-walled.
distribution
The known distribution of Botryobasidium asperulum includes Europe , southern, central and eastern Africa, and Cuba . In Europe the species can be found in Mediterranean regions.
ecology
Botryobasidium asperulum is a saprobiont that colonizes dead wood . They were found on Scots pine ( Pinus sylvestris ) and Gao palm ( Ancistrophyllum secundiflorum ) , among others .
