Hyphomycetes locally isolated from decayed vegetation and studying on their morphological characteristics in axenic cultures revealed three newly recorded species: Akanthomyces johnsonii, Amphichaetella echinata, Atractilina paracitica, and two recorded species: Gliomastix fusigera, Verticimonosporium diffractum. Detailed descriptions and illustrations of the described taxa and discussion on its systematic status and distinguished characteristics were provided. 本文詳細描述及圖析五種臺灣產不完全菌，包括Akanthomyces johnsonii、Amphichaetella echinata、Atractilina paracitica、Gliomastix fusigera 與 Verticimonosporium diffractum，其中首次發現之 A. johnsonii、A. echinata 及 V. diffractum 三者為臺灣新記錄種，另二種為曾經被記錄過之臺灣記錄種 A. paracitica 與 G. fusigera，但以前之文獻欠缺完整形態記載及圖析，故也於此一併提供參考。
