The phyllosphere, endophytic and pathogenic mycota of pepper, cinnamon and tumeric growing in close proximity in a tropical location were studied. Increasing washing cycles up to ten did not significantly alter the number of colonies recovered except in cinnamon which showed reduced numbers recovered beyond seven washes. The isolated fungi were both pathogenic and saprophytic. The fungal genera most frequently isolated from the plant samples by the spread plate method were Aspergillus, Cladosporium, Colletotrichum and Nigrospora. The leaf piece method of isolation most frequently recovered Cladosporium, Colletotrichum, Nigrospora, Pestalotiopsis, Phoma and nonsporing dematiaceous fungi. Three of these species isolated by the leaf piece method(Colletotrichum gloeosporioides on pepper, Pestalotiopsis cf. versicolor on cinnamon, and Phoma sp. on tumeric) are putative pathogens. The diversity of species isolated by washing was less than half that isolated by the leaf piece method. Recovery of species solely by the leaf piece plate method was presumably because these fungi were present primarily inside leaves rather than growing and fruiting abundantly on the leaf surface.
