The golden yellow grape basidia ( Botryobasidium aureum ) 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 conifers . The species is distributed holarctic . The fructification takes place from spring to autumn in mild, damp weather. The anamorphic of the species is known under the name Haplotrichum aureum .
features
Macroscopic features
The golden yellow grape basidia has whitish to light brown-yellowish, spinous fruit bodies, which grow resupinate (i.e. completely adjacent) on their substrate.
Microscopic features
As with all grape basidia , the hyphae structure of the golden yellow grape basidia is monomitic , i.e. it only consists of generative hyphae that branch out at right angles. The basal hyphae are yellowish in color and have long cells. The subhymenial hyphae are hyaline , short-celled, thin-walled and cyanophilic. The species does not have cystidia . The mostly 6-spore basidia of the species grow in nests and are sub-cylindrical. The spores measure 6–10 × 3–4 µm , they germinate in yellowish, lemon-shaped conidia of 20–26 × 9–14 µm.
distribution
The golden yellow grape base is widespread in the Holarctic .
ecology
The golden yellow grape basidia is a saprobiont that colonizes dead wood from deciduous trees in the final phase of decomposition. The fruiting bodies can be found on branches and trunks, where they appear from spring to autumn in damp weather. Hosts include silver birch ( Betula pendula ), red beech ( Fagus sylvatica ) and hornbeam ( Carpinus betulus ).
