Botryobasidium ansosum is a mushroom species from the family of grape basidia relatives (Botryobasidiaceae). It forms resupinate, cobweb-like fruiting bodies thatgrowon the dead wood of conifers . The distribution area of Botryobasidium ansosum includes the temperate Nearctic . No anamorph of the species is known.
features
Macroscopic features
Botryobasidium ansosum has creamy-yellow to ocher-yellow, spinel-like and thin 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 ansosum is monomitic, i.e. it consists exclusively of generative hyphae that branch out at right angles. The basal hyphae are hyaline , mostly 9–15 µm wide, thick-walled and not encrusted. The 6–8 µm thick subhymenial hyphae are hyaline and thin-walled. Like almost all grape basidia, the species does not have cystids , but has buckles on all septa. The seldom four-, mostly six-pore basidia of the species grow in nests, are 17–29 × 7–10 µm in size and are cylindrical. The spores are wide, boat-shaped and usually 8–9 × 4–5 µm in size. They are hyaline, smooth, and thin-walled.
distribution
The known distribution area of Botryobasidium ansosum includes the entire temperate North America .
ecology
Botryobasidium ansosum is a saprobiont that grows on the rotten dead wood of conifers . Well-known substrates include Engelmann spruce ( Picea engelmanni ) and yellow pine ( Pinus ponderosa ).
