Botryobasidium yutajense is a mushroom species from the family of grape basidia relatives (Botryobasidiaceae). It forms resupinate, cobweb-like fruiting bodies thatgrowon stem porlings. The distribution area of Botryobasidium yutajense includes the Venezuelan Yutajé . An anamorph of the species is not yet known.
features
Macroscopic features
Botryobasidium yutajense has grayish to light brown, spinel-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 yutajense is monomitic, i.e. it consists exclusively of generative hyphae that branch out at right angles. The basal hyphae are brown, mostly 8–12 µm wide and not encrusted. The 5–7 µm thick subhymenial hyphae are almost hyaline and thin-walled. All hyphae are simply septate. Like almost all grape basidia, the species has neither cystides nor buckles . The four- to six-pore basidia of the species grow in nests, are 15 × 8.5 µm in size, are approximately ovoid in shape and simply septate at the base. The spores are spindle-shaped to two-pointed and usually 6–7 × 3–3.25 µm in size. They are hyaline and thin-walled.
distribution
The known distribution of Botryobasidium yutajense so far only includes the type locality near the Venezuelan Yutajé on the northern Amazon .
ecology
Botryobasidium yutajense is a saprobiont that colonizes other types of fungus. So far it has only been found dead fruiting bodies of stem porlings.
