Abstract

Four hyphomycetous fungi, including Endophragmia dimorphospora, Epicoccum purpurascens, Helicoma dennisii and Helicoma palmgenum, were newly recorded from Taiwan. These taxa were isolated from air, soil or decaying wood stem or litter covertime by single or mass spores isolation techniques, respectively. The morphological characteristics of the four taxa were closely examined, diagnosed and illustrated. Comparison of the taxa with conspecific isolates from varied geographic regions revealed a slight difference in sporulating structures. The distinctions among them were briefly discussed.
