Ninety seven spores or sporocarps of VAMF were wet sieved from the rhizosphere soil of mycorrhized pteridophytes, from which 25 VAMF species which belonged to the genera of Acaulospora, Gigaspora, Glomus, Sclerocystis and Scutellospora respectively were identified, and the taxonomic characters of the 25 species were described. The Glomus fungi were the dominant VAMF in the rhizosphere soil of pteridophytes, they took up 44% in the identified 25 VAMF (11 species belong to Glomus); the fungi in Acaulospora and Sclerocystis in the next place, they took up 24% and 16% respectively in the identified VAMF; the fungi in the other genera took up 16%. In terms of the relationships of pteridophytes and the VAMF isolated from their rhizosphere soil, there was no specifity between the VAMF and their host.

从具有VA菌根的蕨类植物对应的根际土壤中用湿筛法筛取了97份VA菌根真菌的孢子或孢子果，从中鉴定出了分属于无醒囊霉属、巨孢囊霉属、球囊霉属、硬囊霉属和盾孢囊霉属的VA菌根真菌25种，并对这25种真菌的分类学特征进行了描述；球囊霉属真菌是蕨类植物根际土壤中的优势类群，已鉴定的25种真菌中，有11种属球囊霉属真菌，占44%，其次是无梗囊霉属和硬囊霉属真菌，分别占24%和16%，其他属的VA菌根真菌占16%，从分离鉴定的蕨类植物根际土壤中的VA菌根真菌与蕨类植物的关系看，VA菌根真菌与蕨类植物之间无明显的专一性。
