Botryobasidium intertextum is a mushroom species from the family of grape basidia relatives (Botryobasidiaceae). It forms resupinate, cobweb-like fruiting bodies thatgrowon dead wood of deciduous trees. The distribution area of Botryobasidium intertextum includesa Holarctic areawith Eurasia and North America. An anamorph of the species is not yet known.
features
Macroscopic features
Botryobasidium intertextum has young whitish to old yellowish, spinous or skin-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 intertextum is monomitic, i.e. it consists exclusively of generative hyphae that branch out at right angles. The Basalhyphen are usually 7.5-8 microns wide, thick-walled and the septa with buckles occupied. The 5–7 µm thick subhymenial hyphae, on the other hand, are simply septate and thin-walled. Like most grape basidia, the species does not have cystidia . The six-pore basidia of the species grow in nests, are 15–21 × 5–6.5 µm in size, are cylindrical in shape, sometimes waisted and fitted with a buckle at the base. The thin-walled spores of the fungus are boat-shaped and mostly 6.5–9.5 × 1.8–2.8 µm in size.
distribution
The known distribution of Botryobasidium intertextum covers large parts of Eurasia and North America. Usually it can be found in more northern regions.
ecology
Botryobasidium intertextum is a saprobiont that colonizes dead wood from deciduous trees. Common substrates are mainly oak ( Quercus spp.).
