According to literature "Mykchaylova, O., Lomberg, M., Tsapko, S., & Krasinko, V. MORPHOLOGICAL CHARACTERISTICS OF THE CULTURE CLATHRUS ARCHERI (PHALLACEAE, BASIDIOMYCOTA)." The temperature of 26ºС has been determined as optimal for mycelium incubation, and 39ºC – as critical for culture viability. The morphological characteristics of the fungi on various agar media have been reported. According to the radial growth rate within 0.1–2.9 mm/day, the investigated species belongs to the slow-growing fungi. Nutrient media such as wort agar and compost agar have appeared to be the most favorable for the vegetative growth of С. archeri mycelium
