features
Macroscopic features
Botryobasidium laeve has whitish to yellowish (often olive-tinted), spinel-like and thin 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 Botryobasidium laeve is monomitic, i.e. it consists exclusively of generative hyphae that branch out at right angles. The basal hyphae are yellow-brown, usually 15–20 µm wide and not encrusted. The 5–8 µm thick subhymenial hyphae are hyaline and thin-walled. All hyphae are simply septate. The species has neither cystids nor buckles . The six-pore basidia of the species grow in nests, are 16-20 × 7-9 µm in size, are cylindrical in shape and simply septate at the base. The spores are ellipsoidal to ovoid and usually 5–8 × 2.5–4 µm in size. They are smooth and slightly thick-walled.
distribution
The known distribution of Botryobasidium laeve covers the central and northern part of Europe and extends in the east to the Caucasus.
ecology
Botryobasidium laeve is a saprobiont that colonizes dead wood . It is mainly rotten wood from Bedecktsamern , but also from conifers . Substrates include silver fir ( Abies alba ) or oak ( Quercus spp.). The species prefers moist, densely overgrown habitats.
