【摘要】Four fungal species of Mycena were identificated from the strains isolated from the protocorm and roots of Orchidaceae species.M anoectochial was isolated from the Proocorm of G.elata, M orchidicola, M.dendrobii and M anoectochila respectively separated from the roots of Cymbidium sinense, Dendrobium candidum and Anoectochilus roxburghii. The symbiotic germination test beteen G. Elata seeds and the above fungal species demonstrated that these flingal species can stimulate the seed germination, Which means the species of Mycena may be the key mycorrhizal fungi of G elata, because there were no reports about the other fungal species Which stimulate G.elata seed germination. Besides G. elata, the above species of Mycena also distributed the roots of the other orchids.
