摘要
座隔孢属(Toxosporiopsis Sutton & Sellar)为腔孢纲(Coelomycetes)之一小属,已描述2种。本文报道了该属产自中国的一个新种:中国座隔孢(Toxosporiopsis sinensisW.P.Wu)。新种生于胡桃(Juglans regia L.)枯枝上,它与已知种尖顶座隔孢(Toxosporio-psis capitata Sutton & Sellar)和大孢座隔孢(Toxosporiopsis macrosperma(Cavara)Sutton& Dyko)在子座大小,产孢细胞长度,分生孢子形态、大小,侧丝长度及其外围胶质鞘的有无等特征上差别极大,故另立新种。
The genus Toxosporiopsis was established by Sutton & Sellar in 1966 and the type species is T.capitata Sutton & Sellar.So far,two species have been described in this genus.The specimens on Juglans regia L.from Hebei Province,China,collected by the present author,were identified as a new species of Toxosporiopsis,T.sinensis W.P Wu.The species differs from the other two known species of the genus in size of conidlogenous cells,shape and size of conidia and paraphyses,and presence of mucilaginous sheath on conidiogenous cells, conidia and paraphyses.Latin and Chinese diagnoses were given to the new species.The type specimen (WU910015) is deposited in the Institute of Biology,Hebei Academy of Sciences.
