摘　　要：Enormous fungal species live within the healthy plant tissues,some of which presumably occur in a symbiotic association with host.Some fungal endophytes are widespread and can be found in many different plant species,whereas others are highly specific to single hosts.In this study,we isolated three endophytic fungi from the medicinal plant Vitex negundo.They were identified based on morphological characteristics such as size,shape,and colour of the spore and it was reinforced by 18s rRNA gene sequence analysis.The phylogenetic tree showed that C.gloeosporioides VN1 and Pestalotiopsis virgatula VN2 were closely relationship between.But they were not closely relationship between the other endophytic fungal species that were obtained from geographically different part of the world.This aspect can be further explored to understand the relationships between plant hosts and their fungal endophyte.
