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).
内生真菌是一类与陆生植物健康组织相关的有趣微生物。它们是遗传多样性的巨大宝库。从印度南部不同地区生长的具有民族药学重要性的药用树种（即Terminalia arjuna、Crataeva magna、Azadirachta indica、Holarrhena antidysenterica、Terminalia chebula和Butea monosperma，共11株个体树）的内皮部分分离出了真菌内生菌。从2200个树皮部分中分离出了48种真菌。丝孢纲真菌占主要群体（61%），子囊菌纲（21%）和不育菌丝体（18%）是接下来的主要群体。镰刀菌属、拟盘多毛孢属、漆斑菌属、木霉属、轮枝菌属和毛壳菌属的物种经常被分离出来。在用于内生真菌研究的六种植物中的五种中发现了独特的真菌分类群。物种丰富度的稀疏指数表明，从Terminalia arjuna和Azadirachta indica（各20种）以及Crataeva magna（18种）分离出的树皮部分的物种预期数量最高。
