Abstract：This paper conducted identification on wild microfungi collected from west part of Hunan by tranditional morphological taxonom and molecular systematics methods；analyzed the volatile components of fungus fruiting body pilelus by SPME-GC-MS technology．Results showed that this wild microfungi fungi was identified as Phallus dongsun belonging to a newly identified species．The fruiting body was white in color and of spherical shape．The teleblem（volva）was yellowish in color and of bud shape．The pileus was also yellowish in color and of bell shape with brown-black spore liquid, sticky and special smell．The spore size was （1.80-2.31 μm）×（3.70-4.58 μm）．Spore was of rod shape，and colorless．72 volatile components were identified from pileus of Phallus dongsun．The main components were anisole，phthalyl alcohol，phenethyl alcohol，para-dimethyl ether，of which the relative content of anisole was the highest（35.513%）．There were 23 kinds of aroma component，accounting for 72.805% of the total composition．Those with higher contents were anisole，phenethyl alcohol，para-dimethyl ether，phenylacetaldehyde and n-amyl alcohol．
