Abstract
A study of saprotrophic microfungi associated with the palm Calamus sp. ill Thai forests yielded 88 species, with 40 ascomycetes (45.5%), and 48 anamorphic taxa (54.5%) from 212 fungal collections. The most common fungi were Tetraploa sp. (14.1% of all records), Morenoina palmicola (11.8%), Circinoconis paradoxa (5.2%), Diaporthe sp. (4.7%), and Helminthosporium sp. (4.7%). The percentage of fungi occurring on dry versus damp materials were 68.5% and 31.5%, respectively, with 61% of fungi occurring on petioles and 39% on rachides. The fungi occurring on Calamus sp. are compared with those recorded on other palms in Australia, Brunei, Hong Kong and Thailand.
