从北京东灵山辽东栎（Quercus liaotungensis）和大果榆（Ulmus macrocarpain）的内生真菌中分离到一种新的丝孢真菌--疣孢拟丝孢菌（P. verrucosus）。疣状的该新种在形态上与葡萄孢属真菌及其他类似属的真菌不同，具有微线分生孢子梗和有色疣状分生孢子。基于18 S和28 S rDNA序列数据，采用最大简约法和贝叶斯方法，研究了葡萄孢菌属有性子囊菌的系统发育关系。系统发育分析表明，疣状分枝杆菌属于盘菌目（Pezizales）的焦丝菌科（Pyronemataceae）。
A new hyphomycetous fungus,Micronematobotrys verrucosus, isolated as an endophyte fromQuercus liaotungensisandUlmus macrocarpain the Dongling Mountain of Beijing is described as a new monotypic genus represented byM. verrucosus. This new species differs morphologically fromBotrytis-like fungi and other similar genera in possessing micronematous conidiophores and colored verrucose conidia. The phylogenetic relationships ofMicronematobotrysamong sexual ascomycetes are examined based on 18S and 28S rDNA sequence data using maximum parsimony and Bayesian methods. The phylogenetic analyses suggest thatM.verrucosusis a member ofPyronemataceaeinPezizales.
