The study explored population diversity of fungal endophytes present in the mangrove Sonneratia alba (Pagatpat). These endophytes were isolated, characterized morphologically and molecularly identified by amplification of the ITS gene. Phylogenetic analysis using maximum likelihood was performed on the sequences to elucidate the identification of various isolates. 11 species were isolated from both Tacloban and Matalom sites, but four (4) of these species were unique to Matalom. Based on the computed Shannon-Weiner indices, host mangroves from Matalom (H’=2.738) were more diverse compared to the host mangroves from Tacloban (H’=2.505). Gleason’s Species Richness indices also showed that leaves collected from Matalom (d=4.277) exhibited a greater species richness than leaves from Tacloban (d=3.256). The results implied that alba generally possess the same species of fungal endophytes; but diversity and

The results implied that alba generally possess the same species of fungal endophytes; but diversity and species are affected by the environmental conditions, geographical location and the age of the host tree.
