摘要
本文报导了寄生黑点蚧(Parlatoria zizyphus)的座壳孢属(Ascharsonia)一新种,贵州座壳孢,(Aschersonia guizhouensis Liu et Liang sp. nov.)及寄生粉虱(Aleyrodidae)和盾蚧Diaspidiae的双生座壳孢。(Aschersonia duples Berk.)。新种的主要特征是,孢子器不规则无定形,远离子座基端着生,敞口宽大,150～500×125～350μm。分生孢子拟纺锤形,单孢具油滴,19～20×1.75～2.5μm。侧丝48～118×2～2.5μm。此菌与黄座壳孢(A. flava Petch)和台湾座壳孢(A. formosensis Saw)等6个种有相似之处,但可据以上特征加以区别。双生座壳孢除寄主和子座颜色不同外,其它特征均与(1974)的描述相似。
