本文报道了采自于贵州省贵阳市黔灵山公园的一种寄生蜘蛛的枝穗霉属新种,蛛生枝穗霉Clonostachys aranearum。此新种具有两型产孢结构,A-型产孢结构:轮枝菌型,瓶梗散生,通常2–5个形成轮生体,圆柱形,至顶端略微变细,17.3–27×1.1–1.6μm。B-型产孢结构:帚状,5.4–16.2×1.1–2.2μm,窄楔形,渐细。大量产孢时,分生孢子叠瓦状排列。分生孢子表面光滑,透明,3.2–5.4×1.1–2.1μm,椭圆形,常弯曲。模式标本GZAC QLS0625保存在贵州大学菌种保藏中心。

A new araneogenous fungus, Clonostachys aranearum sp. nov., was collected in Qianlingshan Park of Guiyang, Guizhou Province. The species is characterised by conidiophores dimorphic, A-conidiophores verticilium-like, cylindrical phialides divergent in whorls of 2–5, or single from lower levels, B-conidiophores penicillium-like, and conidia are often arranged in imbricate chains. Conidia are smooth-walled, hyaline, ellipsoid, 3.2–5.4×1.1–2.1μm, mostly curved. The type specimen GZAC QLS0625 has been deposited in GZAC, Guizhou University, Guiyang.
