Botryobasidium robustius is a mushroom species from the family of grape basidia relatives (Botryobasidiaceae). It forms resupinate, cobweb-like fruiting bodies thatgrowon the dead wood of poplars and elms . Botryobasidium robustius is only known from a few localities in Europe. The anamorphic of the species has been described under the name Haplotrichum rubiginosum .
features
Macroscopic features
Botryobasidium robustius 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 robustius is monomitic , i.e. it only consists of generative hyphae that branch out at right angles. The basal hyphae are hyaline , narrow (mostly 8–10 µm wide) and not encrusted. The 5–8 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 15-18 × 8-10 µm in size and are subcylindrical to cylindrical. The spores are narrow ship- to almond-shaped and mostly 7–9 × 3–4 µm in size. They are smooth, thin-walled, and hyaline.
distribution
The known distribution of Botryobasidium robustius is limited to Europe. The finds range from southwest to central Europe to the Caucasus .
ecology
Botryobasidium robustius is a saprobiont that colonizes dead wood . They were found on the rotten branches of elms ( Ulmus spp.) And black poplars ( Popolus nigra ).
