Abstract:Through ecological investigations and experimental studies, it has been shown that C. volvatus is a fungus growing on decaying matter; the carbon source of culture medium comes from glucose, honey, fructose, mannitol, etc; and its nitrogen source from peptone, yeast powder, etc. The best ratio of carbon to nitrogen(C/N) is 20~25: 1, optimum pH 5.5~6.5 and optimal temperature 25~30℃.
