features
Macroscopic features
Botryobasidium isabellinum has yellowish to ocher-colored, 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 isabellinum is monomitic, i.e. it consists exclusively of generative hyphae that branch out at right angles. The basal hyphae are hyaline , narrow (usually 10 µm wide) and not encrusted. The 6–8 µm thick subhymenial hyphae are hyaline and thin-walled. All hyphae are simply septate. The species has neither cystids nor buckles . The four-pore basidia of the species grow in nests, are 15-25 × 8-10 µm in size, are sub-cylindrical in shape and simply septate at the base. The spores are spherical and usually 7-10 × 7-10 µm in size. They are decorated with thorns and have thin walls.
distribution
The known distribution of Botryobasidium isabellinum includes Europe to Norway and Africa to the Republic of the Congo .
ecology
Botryobasidium isabellinum is a saprobiont that colonizes dead wood . These are both flowering plants and conifers . Well-known substrates include Aframomum giganteum , pine ( Pinus pinea ) and silver poplar ( Populus alba ).
