Botryobasidium angustisporum is a mushroom species from the family of grape basidia relatives (Botryobasidiaceae). It forms resupinate, cobweb-like fruiting bodies that usuallygrowon the dead wood of conifers . Botryobasidium angustisporum is common in Europe. An anamorph of the species is not yet known.
features
Macroscopic features
Botryobasidium angustisporum has whitish to cream-colored, in old age yellow to ocher-colored, spinous 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 angustisporum is monomitic , i.e. it only consists of generative hyphae that branch out at right angles. The basal hyphae are hyaline , narrow (mostly 7–10 µm wide) and not encrusted. The subhymenial hyphae are hyaline , thinner and thin-walled, the carrier hyphae are about 4–6 µm wide. The species does not have cystids , but has buckles on many basal and hymenial septa . The six- to eight-pore basidia of the species grow in nests, are 15–20 × 6–8 µm in size, are sub-cylindrical to slightly urn-shaped and have buckled at the base. The spores are narrow, boat-shaped to sub-cylindrical and usually 7-10 × 1.5-2.5 µm in size. They are smooth and thin-walled and often stick together in pairs.
distribution
The known distribution of Botryobasidium angustisporum includes western and northern Europe. The species is considered rather rare.
ecology
Botryobasidium angustisporum is a saprobiont that colonizes dead wood from conifers . The substrates include mainly spruce ( Picea spp.) And pine ( Pinus spp.). The species is often found in Scandinavia in temperate to moist mixed forests of both genera.
