本文描述在台灣蕨類植物觀音座蓮 Angiopteris lygodiifolia 的枯死葉柄上所發現的一種新的絲孢菌真菌，命名為Xylolentia simplex。其種小名“simplex”在拉丁語中意為“simple/簡單”用以致敬已故簡秋源(Chiu Yuan Chien)教授。該新物種具有淺棕色分生孢子，不同於 Xylolentia 屬的其他三個物種，皆具有透明孢子，而與另一個亦具有棕色孢子的物種X. brunneola之區別在於兩者的 ITS、LSU 和 RPB2 序列相似性不高，並且在分生孢子的形狀和大小上亦具有些微差異。此外，本研究亦運用掃描電子顯微鏡技術首次揭露了 Xylolentia 的分生孢子產孢形式為特殊的環頸型。

A new hyphomycetous fungus found on dead petioles of the fern Angiopteris lygodiifolia in Taiwan is described as Xylolentia simplex in honor of late Prof. Dr. Chiu Yuan Chien (簡秋源; Chien 簡 and the Latin “simplex” both meaning “simple”). The new species differs from other three hyaline-spored species of Xylolentia by its pale brown conidia and from the other brown-spored species X. brunneola by low identities of the ITS, LSU and RPB2 sequences and minute differences of conidium shape and size. Scanning electron microscopy reveals annellidic conidiogenesis in Xylolentia for the first time.
