Botryobasidium digitatum is a mushroom species from the family of grape basidia relatives (Botryobasidiaceae). It forms resupinate, cobweb-like fruiting bodies thatgrowon dead wood . Botryobasidium digitatum has a species area that includes Central and South America . The anamorphic of the species is not yet known.
features
Macroscopic features
Botryobasidium digitatum has light ivory-colored, flour-dust-like or spider-like fruit 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 digitatum is monomitic , i.e. it only consists of generative hyphae that branch out at right angles. The basal hyphae are hyaline to slightly yellowish, mostly 7–12 µm wide and not encrusted. The up to 6-11 µm thick subhymenial hyphae are hyaline , thin-walled and cyanophilic. The species has only a few, 60–105 × 10–12 µm large cystids and no buckles . The mostly six-pore basidia of the species grow in nests, are 17–25 × 9–12 µm in size, are initially stubby-ovoid, later urn-shaped and simply septate at the base. The spores are elongated, cartridge-shaped to boat-shaped and 10–12 × 4–5.5 µm in size. They are smooth, thin-walled and have a distinct extension.
distribution
The known distribution of Botryobasidium digitatum includes Panama and Colombia , the species has so far only been found very rarely.
ecology
Botryobasidium digitatum is a saprobiont that colonizes dead wood . The substrate spectrum is not known in detail; the holotype comes from a piece of completely charred wood.
