Sixty-nine isolated as endophytic fungi, had been
successfully segregated from plant samples of six species
mangrove plants which are growing in Bunaken Island and
Sampiran Beach, North Sulawesi. Nineteen isolates (28%)
were identified to species, 21 isolates (30%) turn into
genus, and 29 isolates (42%) do not have asexual spores
which were hardly to identify microscopically and then all
be classified as unidentified isolates (Table-1). Two
species of two genera (Guignardiaand Talaromyces)
catagorized into group of Ascomycotina and 9 species of 7
genera (Aspergillus, Colletotrichum, Fusarium,
