Botryobasidium ponderosum is a mushroom species from the family of grape basidia relatives (Botryobasidiaceae). It forms resupinate, cobweb-like fruiting bodies thatgrowon dead wood of yellow pines . The distribution area of Botryobasidium ponderosum includes the southeast of California . The anamorphic of the species is known under the name Haplotrichum ponderosum .
features
Macroscopic features
Botryobasidium ponderosum has light gray to off-white, 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 ponderosum is monomitic, i.e. it consists exclusively of generative hyphae that branch out at right angles. The basal hyphae are yellow, usually 7–8 µm wide, thick-walled and not encrusted. The 4–6 µm thick subhymenial hyphae are almost hyaline and thin-walled. Like almost all grape basidia, the species does not have cystids , but has buckles on all septa. The six- to eight-pore basidia of the species grow in nests, are 7.5–10 × 4–5 µm in size and approximately urn-shaped. The spores are boat-shaped and usually 6–7.5 × 2.5–3 µm in size. They are hyaline, smooth, and thin-walled.
distribution
The known distribution of Botryobasidium ponderosum includes the southeast of California , where they occur particularly in the Black Fountains .
ecology
Botryobasidium ponderosum is a saprobiont that grows on the dead wood of yellow pine ( Pinus ponderosa ). It fructifies in the spaces between brown rotten , torn pieces of wood of this type.
