The whitish grape basidia ( Botryobasidium candicans ) 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 deciduous trees, more rarely on conifers . The species is Holarctic and distributed in northern India. The fructification takes place from spring to autumn in mild, damp weather. The anamorphic of the species is known under the name Haplotrichum capitatum .
features
Macroscopic features
The whitish grape basidia has whitish, spider-like fruiting bodies that grow resupinate (i.e. completely adjacent) on its substrate and appear slightly reticulate under the magnifying glass.
Microscopic features
As with all grape basidia , the hyphae structure of the whitish grape basidia is monomitic , i.e. it only consists of generative hyphae that branch out at right angles. The basal hyphae are hyaline , narrow (<15 µm ) and long-celled. The subhymenial hyphae are hyaline , short-celled, thin-walled and cyanophilic, which means that they can be easily stained blue. The species does not have cystids or buckles . The mostly 6-spore basidia of the species grow in nests and are sub-cylindrical. The spores measure 7–8 µm and germinate in 500 × 6–9 µm large conidiophores , which are populated with 14–19 × 8–10 µm large conidia . Often only the imperfect stage is found without basidia or spores.
distribution
The whitish grape basid is Holarctic , widespread in the Canary Islands and northern India. The area is temperate - subatlantic .
ecology
The whitish grape basidia is a saprobiont that colonizes dead wood from deciduous trees, more rarely conifers in the final phase of decomposition. The fruit bodies can be found on debarked wood, where they appeared in damp weather in late spring and early autumn. Hosts include silver birch ( Betula pendula ), common ash ( Fraxinus excelsior ) and hornbeam ( Carpinus betulus ).
