The anamorphic of the species is unknown.
features
Macroscopic features
Botryobasidium stigmatisporum has light gray, spider-like 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 stigmatisporum is monomitic , i.e. it consists only of generative hyphae that branch out at right angles. The basal hyphae are hyaline to yellowish, narrow (mostly 9–12 µm wide) and not encrusted. The 6–7 µm thick subhymenial hyphae are hyaline, thin-walled and cyanophilic. The species does not have cystids or buckles . The rarely eight-, mostly six-pore basidia of the species grow in nests, are 12–18 × 6–8 µm in size and are constricted to suburniform. The spores are ship- to spindle-shaped and mostly 5.5–7.5 × 3–4 µm in size. They are finely ornamented, slightly thick-walled and yellowish to brownish.
distribution
The known distribution of Botryobasidium stigmatisporum only includes the Mascarene island of La Réunion .
ecology
Botryobasidium stigmatisporum is a saprobiont that colonizes dead wood from deciduous trees. The only known substrate is an unspecified Philippia species.
