10.22376/ijpbs.2019.10.1.p1-12 Volume 4 Issue 1 2013 (January - March) Endophytic fungi were isolated from the inner bark of lessThan i greaterThan Ventilago madrasapatna, lessThan /i greaterThan a well-known medicinal plant of India. It was investigated for endophytic mycoflora as a possible source of bioactive secondary metabolites. A total 66 isolates of 14 species belongs to 5 classes, were studied adopting a standard isolation protocol. The colonization frequency of the endophytic fungi was reported as 87.84%. Fungus composition included 6.25% Eurotiomycetes, 9.3% Dothideomycetes, 14.26% Soradariomycetes, 11.08% Ascomycetes, 2.6% Leotiomycetes and 1.3% isolates were classified under Mycelia sterilia. The sterile endophytic fungi presently reported are expected to add to the list of new fungal species. Among the endophytic flora, lessThan i greaterThan Fusarium oxysporum was lessThan /i greaterThan found to be the core-group fungus with a colonization frequency of 34.22%. lessThan i greaterThan Cladosporium cladosporiodes lessThan /i greaterThan and lessThan i greaterThan Botrytis sp lessThan /i greaterThan . are present only in bark of plant collected in Belur forest region. These results indicated that distribution of endophytic fungi is mainly influenced by environment factors. K.N.RAVINDRA, THOYAJAKSHA, M.NARAYANAPPA, AND P.
