Phellinus igniarius is a kind of rare medicinal fungi. It belongs toBasidiomycotina, Hymenomycetes, Polyporales, Polyporaceae, Phellinus in taxology.Phellinus is a large genus of Polypora, it was depicted that there were more than 250classified unites on the earth, at present 62 species in our country. This article summarizedthe research status of Phellinus igniarius, a kind of rare medicinal fungi, including growthcharacter, artificial cultivation, liquid fermentation, pharnacodynamic function and soforth. Its developing prospect was analyzed. The antagonistic reaction, peroxidase isozymeand esterase isozyme analysis of 7 Phellinus igniarius strains which collected by edible labof agricultural college of Yanbian university were tested in this paper. The results ofantagonistic reaction showed that S3, S6, S7 strains had affinity; and peroxidase isozymeshowed the zymogram among S3, S6, S7 strains are very same indicated that they hadnearer affinity; moreover S 6 and S7 had much nearer affinity, but the others had muchfarther affinity or had no affinity. And 1 band in the esterase isozyme zymogram atRf=0.805 was all the same for 7 Phellinus igniarius strains tested, In conclusion, the threeexperiment results are almost coincidence, and compared the affinity by analysis thesimilar coefficient of each strains.
