Abstract

A dematiaceous hyphomycete with erect unbranched conidiophore stipes and Cladosporium-like branched conidial chains arranged at nodes along the stipe was found on living leaves of wild banana (Musa itinerans) in Taiwan. Scanning electron microscopy indicated a type of conidiogenous loci differing from that of Cladosporium by lacking the cleft between raised center and margin. Molecular phylogenetic analyses of several loci (LSU, ITS, TEF, RPB2) indicated a relationship with cercosporoid fungi (Mycosphaerellaceae). Since there is no other known lineage with similar morphology or DNA sequences, the new genus and species Cladocillium musae is proposed.
