    摘要:

    【目的】调查发现我国稀有但重要的虫生束梗孢类真菌。【方法】采用经典形态学及生态学特征对研究标本进行鉴定。【结果】在寄生鞘翅目昆虫的标本中,发现我国一拟多头束霉新记录种,金龟拟多头束霉Tilachlidiopsis scarabaei L.S. Olive,其形态特征为:寄主昆虫长约15 mm,宽4 mm。孢梗束下部深褐色,上部白色,长约36 mm,宽约1.8 mm,头状,可简单分枝。瓶梗锥形,少数棒状,顶端变细,长约19.4?25.9 μm,宽1.1?2.2 μm,在孢梗束的球状头部,呈栅栏状密集排列;在近头部的柄上瓶梗顶侧生于简单分枝的分生孢子梗上。分生孢子大多椭圆形,(2.2?3.2) μm×(1.1?2.2) μm;近柱形,(4.3?5.4) μm×(1.1?2.2) μm;少数球形, 1.1?2.2 μm。【结论】经文献检索和鉴定,金龟拟多头束霉为我国报道的新记录种。

    Abstract:

    [Objective] To investigate and discover some rare and important stilbellaceous entomogenous fungi from China. [Methods] The classical morphological and ecological characters were used for identification of specimens. [Results] A few Tilachlidiopsis specimen parasitic to coleopteran was identified as T. scarabaei L.S. Olive. The morphological characters of T. scarabaei were described as follows: Synnemata about 36 mm long, 1.8 mm wide, dark brown below, white above, sometimes branched, polycephalous. Phialides with palisade arrangement in a compact hymenium-like covering the heads, but terminal or lateral phialides occurring on the simple conidiophores in the stipe close to the heads, mostly conical, rarely clavate, and tapering toward the top, (19.4?25.9) μm×(1.1?2.2) μm. Conidia, mostly elliptical, (2.2?3.2) μm×(1.1?2.2) μm; subcylindric, (4.3?5.4) μm×(1.1?2.2) μm; rarely spherical, 1.1?2.2 μm. [Conclusion] The specimen is reported as T. scarabaei L.S. Olive, which is a new record species in China.
