The fluffy grape basidia ( Botryobasidium conspersum ) 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 and conifers . The species is Holarctic and distributed in the Azores . The fructification takes place from spring to late autumn. The anamorphic of the species is known under the name Haplotrichum conspersum .
features
Macroscopic features
The loosely flaky grape base has whitish-gray, spinelike 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 the loose, flaky grape basidia is monomitic , i.e. it consists only 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. 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 are ellipsoidal and germinate in 360 × 11 µm large conidiophores , which are covered with 14–18 × 10–15 µm large, finely ornamented conidia on the inside . Often there is only the imperfect stage without basidia or stages with basidia and conidiophores.
distribution
The loosely flaky grape base is holarctic- continental and widespread on the Azores .
ecology
The loosely flaky grape basid is a saprobiont that colonizes dead wood from deciduous trees and conifers in the final phase of decomposition. The fruiting bodies are found on fallen branches and on stripped trunks, where they appeared in damp weather in spring and late autumn. Hosts include Prunus species, oaks ( Quercus spp.) And red beeches ( Fagus sylvatica ).
