Botryobasidium olivaceum is a mushroom species from the family of grape basidia relatives (Botryobasidiaceae). It forms resupinate, cobweb-like fruiting bodies that usuallygrowon dead wood . The range of Botryobasidium olivaceum includes the West African Gabon . An anamorph of the species is not yet known.
features
Macroscopic features
Botryobasidium olivaceum has freshly olive-gray, dry 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 olivaceum is monomitic, i.e. it consists exclusively of generative hyphae that branch out at right angles. The basal hyphae are brownish, thick-walled, usually 4–10 µm wide and not encrusted. The 6–10 µm thick subhymenial hyphae are yellow-brownish (paler towards the top), strongly branched and thin-walled. All hyphae are simply septate. The species has neither cystids nor buckles . The mushroom initially has slightly spherical, later elongated basidiols . The six- to eight-pore basidia of the species grow in nests, are 12-17 × 7-9 µm in size, are waisted in the middle and simply septate at the base. The spores are elongated to kidney-shaped and usually 5–6.2 × 3–4 µm in size. They are smooth, hyaline, and thin-walled.
distribution
The known distribution of Botryobasidium olivaceum only includes the type locality in Gabon .
ecology
Botryobasidium olivaceum is a saprobiont that colonizes dead wood . The substrates have not yet been determined, the species has always been found in coastal biotopes.
