Endophytic fungi represent an interesting group of microorganisms associated with the healthy tissues of terrestrial plants. They represent a large reservoir of genetic diversity. Fungal endophytes were isolated from the inner bark segments of ethnopharmaceutically important medicinal tree species, namely Terminalia arjuna, Crataeva magna, Azadirachta indica, Holarrhena antidysenterica, Terminalia chebula, and Butea monosperma (11 individual trees), growing in different regions of southern India. Forty-eight fungal species were recovered from 2200 bark segments. Mitosporic fungi represented a major group (61%), with ascomycetes (21%) and sterile mycelia (18%) the next major groups. Species of Fusarium, Pestalotiopsis, Myrothecium, Trichoderma, Verticillium, and Chaetomium were frequently isolated. Exclusive fungal taxa were recovered from five of the six plant species considered for the study of endophytic fungi. Rarefaction indices for species richness indicated the highest expected number of species for bark segments were isolated from T. arjuna and A. indica (20 species each) and from C. magna (18 species).
