Botryobasidium simile is a mushroom species from the family of grape basidia relatives (Botryobasidiaceae). It forms resupinate, cobweb-like fruiting bodies thatgrowon dead wood of deciduous trees. The range of Botryobasidium simile includes the temperate Holarctic . The anamorphic of the species has been described under the name Haplotrichum simile .
features
Macroscopic features
Botryobasidium simile has whitish to cream-colored, 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 simile 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 6–8 µm thick subhymenial hyphae are hyaline , short-celled, thin-walled and cyanophilic. The species does not have cystids or buckles . The rarely four- or eight-, mostly six-pore basidia of the species grow in nests, are 10–18 × 6.5–8.5 µm in size and have a slight stalk. The spores are ship- to spindle-shaped and mostly 9–11 × 3–3.5 µm in size. They are smooth, thin-walled, and hyaline.
distribution
The known distribution of Botryobasidium simile includes the temperate Holarctic with northern Europe and North America .
ecology
Botryobasidium simile is a saprobiont that colonizes dead wood from deciduous trees. known substrates include white poplar ( Populus alba ) and common ash ( Fraxinus excelsior ).
