摘要：Fungi associated with dead leaves and stems of Thysanolaena latifolia and Saccharum spontaneum were collected and identified at two sites. T. latifolia yielded 67 taxa, comprising 24 ascomycetes, 33 hyphomycetes, 9 coelomycetes and 1 myxomycete. The most common genera were Lepto-sphaeria, Niptera, Periconia, Septoria, Stachybotrys, Tetraploa, and Verticillium. S. spontaneum yielded 79 taxa comprising 32 ascomycetes, 37 hyphomycetes, and 10 coelomycetes. The most common genera were Cladosporium, Massarina, Periconia and Tetraploa. The highest species diversity index was recorded on S. spontaneum (H = 6.5), while T. latifolia was lower (H = 5.5). The mycota at the two sites differed significantly in species composition. Percentage similarity for T. latifolia between the two sites was 50.5% while for S. spontaneum it was 52.3 %. A comparison of the fungi occurring on these grasses with those on other monocotyledonous host from tropical regions is presented. Drumopama moonseti and Pycnothyriopsis sp. were reported as rare species in this study. Dendrographium thysanolaenae ined. is considered new to science
