Abstract: Survey was made on 44 species of pteridophytes in Yunnan provance in terms of VA mycorrhizae. The coevolution of pteridophytes and VA mycorrhizal fungi was discussed. The results shown that 18 species of pteridophytes were typically mycorrhized, the fungi which infected pteridophytes to form VA mycorrhiza belong to the genus of Glomus. VA mycorrhiza was a primitive biological character, it has a positive evolutionary indication in the origin and evolution of land plants.
