The ability of the medicinal xylotrophic basidiomycetes Lentinus edodes, Pleurotus ostreatus, Ganoderma lucidum and Grifola frondosa to produce typical and atypical fruiting bodies with viable basidiospores in submerged and solid-phase culture under stationary conditions in a beer wort-containing medium under cold stress was shown. The examined mushrooms, when not exposed to temperature stress, did not form fruiting bodies. In solid-phase culture in an agarized medium after cold treatment, the basidiome formation period was shortened by 1.5–2 times. Furthermore, the use of a mycelium subjected to temperature stress for inoculation induced and accelerated the formation of fruiting bodies on an industrial wood substrate, which is of great biotechnological importance.

Key words:    xylotrophic basidiomycetes, submerged and solid-phase cultivation, typical and atypical fruiting bodies, cold stress
