Abstract��OBJECTIVE To investigate extensively the cultural endophytic fungal community colonized mainly in the roots of five orchid medicinal plants species. METHODS Cultural endophytic fungi were identified using the morphological METHODS and molecular sequences. RESULTS A total of 241 strains of fungi were isolated and identified into at least 52 genera. Among them, Fusarium(14.9%), Colletotrichum(12.9%), Xylaria(5.4%) and Alternaria(3.7%) were dominated.Ten interested fungal strains were identified, including Dark septate endophyte (DSE) and Orchid mycorrhizal fungi(e.g. Tulasnella and Sebacina).CONCLUSION Fungal taxa and richness are related to host plant species and its geological distribution. This study provides important fungal resources for cultivation of orchid medicinal plants and screening of bioactive compounds in the future.
