摘　　要：早熟禾是优良的草坪草和牧草,近年来,天津出入境检验检疫局多次从进境的草地早熟禾、加拿大早熟禾及一年生早熟禾上截获一种腥黑粉菌,暂名为Tilletia sp.。针对T.sp.、早熟禾上的形态相近的T.sterilis、T.togwateei,以及同属近似种雀麦腥黑粉菌T.bromi和禾草腥黑粉菌T.fusca在冬孢子形态特征、萌发特性及细胞学性状等方面进行了系统比较。结果表明,Tilletia sp.与T.sterilis、T.togwateei存在较大差异,与T.bromi和T.fusca差别不明显;截获菌与Tilletia sp.在菌瘿、冬孢子形态特征上与T.bromi更为接近,根据研究结果将Tilletia sp.定名为T.bromi。Several spicies of the bluegrass （Poa L.） are important herbage and lawngrass. In recent years,an undetermined species of Tilletia （T. sp.） which causes bunt smut of Poa spp. had been frequently intercepted from introduced seeds of Kentucky bluegrass,Canada bluegrass and annual bluegrass. An integrated comparison of the spicies on morphological,germination and cytological characters of teliospores with several morphologically allied Tilletia species,T. sterilis,T. togwateei,T. bromi and T. fusca was carried out. The result showed that there are significant discrepancies between T. sp. and T. sterilis,T. togwateei,while the differences between T. sp. and T. bromi,T. fusca are not obvious. The T. sp. is more closer to T. bromi morphologically. According to the results,we considered that the T. sp. and T. bromi are same species.
