Abstract
Enumeration of the endophytic fungi from the red listed, critically endangered medicinal plant,
Coscinium fenestratum was investigated for the first time. The ubiquitous presence of 41
endophytic fungi belonging to sixteen different taxa was identified from 195 samples of
healthy leaves and stem using traditional morphological methods. The overall colonization rate
of endophytes in both the leaf and the stem was found to be 21.02%.The stem showed low
percentage frequency of colonization of the endophytic fungi when compared to leaf
segments. Among the endophytic flora, Phomopsis jacquiniana was found to be the core-group
fungus with a colonization frequency of 4.6%.
