Over the years, there have been continuous updates in the taxonomy of coelomycetes. In particular, traditional classification has been revised and updated based on extensive collections supplemented with morphological examinations and phylogenetic analyses. Most of the data available are scattered in the literature. In an attempt to ease the work o...

Mangroves grow adjacent to estuarine regions of the tropics and subtropics. Fungi cause diseases in mangroves; however, it is not clear if the diseases are unique to mangrove species or ubiquitous. In this study, we identified a species of Alternaria, a genus comprising with saprobic and pathogenic species of a large number of plants. The genus is...

During an ongoing research survey of saprobic fungi in Thailand, four coelomycetous strains were isolated from decaying leaves in Chiang Mai and Phitsanulok Provinces.
