摘要
Helicoma chiayiense sp. nov. and Helicosporium taiwanense sp. nov. on decaying wood submerged in a freshwater stream of Alishan area, Chiayi County, Taiwan, are described and illustrated with light and scanning electron micrographs. Helicoma chiayiense is distinct in having hyaline conidiophores arising from repent mycelium, producing broad conidia that bear secondary conidia. Helicosporium taiwanense is distinct in having robust poly-denticulate conidiophores producing conidia with a wide conidial filament. The phylogenetic relationship of these species was sought among representative taxa of the helicosporous hyphomycetes by comparing their ITS of the ribosomal DNA (rDNA).
