报道了采自贵州省宽阔水自然保护区的球束梗孢属一新种——弯孢球束梗孢,对其进行了形态描述和基于ITS-5.8SrDNA序列的分子研究。在球束梗孢属中与具有类似弯曲的分生孢子的G.formosana进行了比较,本种瓶梗基部为近球形膨大,分生孢子较大,4.7-11×1.6-2.4μm;而Gformosana瓶梗基部是纺锤形,分生孢子较小,3.5-4×1.5-2.2μm。
Gibellula curvispora sp. nov. collected from Kuankuoshui Nature Reserve of Guizhou Province was described and illustrated and analyzed based on ITS rDNA molecular study. The classification position and relationship with G formosana in the genus Gibellula are discussed. The main differences between these two species are as follows: phialides of G curvispora are subglobose, and conidia are 4.7-11×1.6-2.4μm; phialide of G formosana is fusiform, and conidia are 3.5-4×1.5-2.2μm.
