The buckled grape basidia ( Botryobasidium subcoronatum ) is a mushroom species from the family of grape basidia relatives (Botryobasidiaceae). It forms resupinate , cobweb-like fruiting bodies that grow on the trunks of dead conifers and deciduous trees. The species is restricted to Europe. The fructification takes place in spring to late autumn. There is no known anamorphic of the buckled grape basidia.
features
Macroscopic features
The buckle-wearing grape basidia has flaky, spider-like fruit bodies that grow resupinate (i.e. completely adjacent) on its substrate and appear slightly reticulate under the magnifying glass. They are initially white, later ocher yellow.
Microscopic features
As with all grape basidia , the hyphae structure of the buckle-bearing grape basidia is monomitic , i.e. it only consists of generative hyphae that branch out at right angles. The basal hyphae are thick-walled, narrow (7–10 µm ) and long-celled. The 5–6 µm wide subhymenial hyphae are thin-walled. The species does not have cystids , but unlike many members of the generic species, it has buckles on all septa . The mostly 6-spore, 20-25 × 7-9 µm large basidia of the species grow in nests and are subcylindrical. At their base they are simply septate and have a buckle , which clearly distinguishes them from other types of grape basidia. The spores are narrow, boat-shaped, 6–8 × 2.5–3 µm in size and have an apex.
distribution
The buckle-bearing grape base is spread across Europe and known from all European countries. The species is considered common everywhere.
ecology
The buckle-bearing grape basid is a saprobiont that colonizes dead wood from conifers and deciduous trees. The fruiting bodies can usually be found on lying and often debarked trunks and branches in the optimal and final phase. Common spruce ( Picea abies ), red beech ( Fagus sylvatica ) and pine ( Pinus spp.) Are common substrates .
