丝孢菌目Pusogliograma incum产生松散且经常磨损的合生体，具棕色柄和分叉的头状花序，分生单细胞分生分生细胞和深深收缩的分生孢子。皮质拉玛拉霉菌是在P.具有非常相似的微形态特征。两属均为单型。Ps的正型。糯米是贫瘠的。我们重新收集了P。在模式地区附近的印度。在本文中，我们用原始插图对该属和种进行了选型，并用一新标本对该种进行了表型。从表型标本中提取表型外培养物，用于对核RNA操纵子区域进行测序，以确定物种的系统发育关系。该真菌属于新近描述的土贝目Wiesnerimycetaceae科，与孢子常规、粘稠的孢子属Wiesnerimycetaceae形成姐妹群。我们澄清了假绿僵菌的一般概念，提出了一个新的描述和图解。劳云金威氏酵母为加拿大首次报道。皇冠版权(C)2014，由爱思唯尔公司代表日本真菌学会出版。版权所有。
The hyphomycete Pseudogliophragma indicum produces loosely constructed and often frayed synnemata, with a brown stipe and a divergent capitulum with monoblastic conidiogenous cells and deeply constricted phragmoconidia. Ramaraomyces corticola was described nine years after Ps. indicum with very similar micro-morphological characters. Both genera are monotypic. The holotype of Ps. indicum is depauperate. We re-collected Ps. indicum near the type locality. In this paper, we lectotypify the genus and species with the original illustration, and epitypify the species with a new specimen. An ex-epitype culture was derived from the epitype specimen and used to sequence regions of the nuclear RNA operon to determine the phylogenetic relationships of the species. The fungus belongs to the recently described family Wiesneriomycetaceae in the Tubeufiales, forming a sister group with the sporodochial, slimy spored genus Wiesneriomyces. We clarify the generic concept of Pseudogliophragma, propose Ramaraomyces as a synonym, and provide a new description and illustration. Wiesneriomyces laurinus is reported for the first time from Canada. Crown Copyright (C) 2014 Published by Elsevier B.V. on behalf of the Mycological Society of Japan. All rights reserved.
