Tiger strains of wild mushroom spores and the mycelium,a different time of ultraviolet radiation mutagenesis,test results showed that the variant strains from the eight selected in the two strains.4 min mycelium UV mutation of the strain mycelial growth speed,covered with PDA slant and the original medium bottles of the time were 7 and 11 days; cell thick and white,long out of the fruiting body of meat Jungai Thick,Junbing stout,the first fruiting reached 50 g.4 min spores mutation of the strain spores four days to germination,and the germination rate increased 9.1 percent,PDA slope covered with seven days,11 days of the original medium covered with bottles,and white cell thick,stout and tidy.Hyphae and spores mutation 4 min strains have good potential value Deyong,pending further study.
