The invention relates to a hypsizygus marmoreus stock culture mutagenesis method. The hypsizygus marmoreus stock culture mutagenesis method specifically comprises the following steps: after a stock culture which is stored is activated, the stock culture is subjected to irradiation by an ultraviolet lamp for three times for mutation after being sorted out; then mutant strains are purified; and lastly the mutant hypsizygus marmoreus strain bodies are cultured and sorted out for multiple times to obtain best mutant strains. According to experiments and regional trials of the mutant strains the hypsizygus marmoreus stock culture mutagenesis method has the advantages that the growing speed of mycelium is high, the growth cycle of the mycelium is short, hypsizygus marmoreus comes out early, and the culture period can be shortened by 10 to 20 days; the yield of the hypsizygus marmoreus is high, more specifically, after the mutagenesis of the stock culture, the yield of the hypsizygus marmoreus is increased by 20% to
