Abstract

Two new species of Cladorrhinum, C. flexuosum and C. microsclerotigenum, are described and their sequences of the 5.8S and 28S ribosomal DNA and internal transcribed spacers 1 and 2 of the ribosomal RNA gene cluster analyzed. Cladorrhinum flexuosum, isolated from soil in Spain, forms fast-growing, dull yellow colonies, flexuous conidiophores and globose to dacryoid conidia. Cladorrhinum microsclerotigenum, isolated from Musa sp. in Turkey, strongly resembles Cladorrhinum phialophoroides in the production of abundant terminal phialides, ellipsoid conidia and microsclerotia in culture. It differs from C. phialophoroides in its ability to grow at 36 C and high number of intercalary phialides, which only infrequently occur in C. phialophoroides.

摘要

描述了两种新的 Cladorrhinum 物种，即 C. flexuosum 和 C. microsclerotigenum，并分析了它们的 5.8S 和 28S 核糖体 DNA 以及核糖体 RNA 基因簇的内部转录间隔区 1 和 2 的序列。C. flexuosum 是从西班牙土壤中分离出来的，形成生长迅速、暗淡黄色的菌落，弯曲的分生孢子梗和球形至泪滴形的分生孢子。C. microsclerotigenum 是从土耳其的 Musa sp. 中分离出来的，它在大量末端瓶梗、椭圆形分生孢子和培养中的微菌核的产生方面与 Cladorrhinum phialophoroides 非常相似。它与 C. phialophoroides 的不同之处在于它能够在 36°C 下生长，并且具有大量的中间瓶梗，而中间瓶梗在 C. phialophoroides 中很少出现。
