The boat-pore grape basidia ( Botryobasidium botryosum ) is a mushroom species from the family of grape basidia relatives (Botryobasidiaceae). It forms white, resupinate, cobweb-like fruiting bodies that grow on the rotten trunks of dead deciduous trees and conifers . The known distribution of the species is limited to Europe. The fructification takes place all year round in mild, damp weather. No anamorph of the species is known.
features
Macroscopic features
The shuttle-pored grape basidia has thin, whitish and spinel-like fruiting bodies, which grow resupinate (i.e. completely adjacent) on their substrate.
Microscopic features
As with all grape basidia , the hyphae structure of the shuttle-pored grape basidia is monomitic , i.e. it consists only of generative hyphae that branch out at right angles. There are no buckles . 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 cystidia . The mostly four-pore basidia of the species grow in nests and are sub-cylindrical. The eponymous boat-shaped spores measure 8–12 µm in length and do not germinate in conidia .
distribution
The Schiffchensporige Traubenbasidie is holarctic spread and moderate - Atlantic to find air. The distribution ranges from Spain across Central Europe to southern Fennoscandinavia .
ecology
The boat-pore grape basidia is a saprobiont that colonizes dead wood from deciduous and coniferous trees in the optimal to final phase of decomposition. The fruiting bodies can be found on branches and trunks, where they appear all year round in damp weather. Hosts include oak ( Quercus spp.), Norway spruce ( Picea abies ), silver fir ( Abies alba ) and forest pine ( Pinus sylvestris ).
