A study was undertaken to collect and identify saprobic fungi associated with Musa spp. (banana) from Taiwan, China, and Thailand. Samples were collected during the dry season and their morpho–molecular relationships were investigated. Five brown pleosporalean hyphomycetous taxa in Periconiaceae and Torulaceae viz. Periconia cortaderiae, P. delonicis, Torula chromolaenae, T. fici, and T. masonii were identified for the first time from Musa spp. (Musaceae). Phylogenetic analyses of a combined SSU, LSU, ITS, RPB2 and TEF DNA sequence dataset further justified the taxonomic placements of these five taxa in the above mentioned families. Periconia delonicis is reported for the first time on a monocotyledonous host and T. masonii is the first geographical record from Taiwan.
