Botryobasidium curtisii 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. Botryobasidium curtisii has a species range that includes North America , Eurasia and South America . The anamorphic of the species is known under the name Haplotrichum curtisii .
features
Macroscopic features
Botryobasidium curtisii has gray-white, spinel-like fruiting 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 curtisii is monomitic , i.e. it consists only of generative hyphae that branch out at right angles. The basal hyphae are slightly yellowish, mostly 5–8 µm wide and not encrusted. The up to 4–8 µm thick subhymenial hyphae are hyaline , thin-walled and cyanophilic. The species does not have cystids or buckles . The mostly six-pore basidia of the species grow in nests, are 11–14.5 × 6.5–7.5 µm in size, are initially spherical, later ellipsoidal to ovoid and simply septate at the base. The spores are approximately cartridge or boat-shaped and 7.5–9.5 × 2.5–3 µm in size. They are smooth and thin-walled and have a distinct extension.
distribution
The known distribution of Botryobasidium curtisii includes southern North America , the Caribbean , South America and western Africa .
ecology
Botryobasidium curtisii is a saprobiont that colonizes dead wood from deciduous trees . The exact substrate spectrum of this grape base is not known.
