Botryobasidium danicum is a mushroom species from the family of grape basidia relatives (Botryobasidiaceae). It forms resupinate, cobweb-like fruit bodies thatgrowon the dead wood of deciduous and coniferous trees. Botryobasidium danicum lives ina Holarctic areawith Europe and North America . An anamorphic is not yet known.
features
Macroscopic features
Botryobasidium danicum has whitish to yellowish, spinel-like and thin fruit 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 danicum is monomitic , i.e. it consists exclusively of generative hyphae that branch out at right angles. The basal hyphae are hyaline , narrow (mostly 8–12 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- or six-pore basidia of the species grow in nests, are 15–20 × 8–12 µm in size, are sub-cylindrical in shape and simply septate at the base. The spores are narrow, boat-shaped and mostly 12–15 × 3–5 µm in size. They are smooth and thin-walled.
distribution
The known distribution of Botryobasidium danicum includes Europe and North America and thus a Holarctic area. The distribution is mainly limited to humid oceanic or sub-oceanic climates.
ecology
Botryobasidium danicum is a saprobiont that colonizes dead wood . As a rule, these are conifers such as Douglas firs ( Pseudozuga menziesii ); Sometimes, however, deciduous trees such as stone oaks ( Quercus ilex ) are also populated.
