笔者用过去菌的形态特征分类,但也不完全依靠前面叙述这种分类的方式,而是对分类的标准进行了新特性的探讨。其结果在夏孢子、冬孢子世代上,明确的提出以下几点作为分类的特征: (1)担子孢子的形态和大小:把形成冬孢子堆的病叶放在培养皿内保湿培养,用显微镜观察落下的担子孢子。以前的锈菌分类不重视担子孢子,有的锈菌有特殊的特征,如以紫苑属(Aster)、Kalimeris属植物为寄主的C.asterum的担子孢子为球形 The author uses the morphological characteristics of the past, but does not completely rely on the previous description of this classification, but on the classification criteria for a new feature. The results in the summer spores, winter spore generation, clearly put forward the following characteristics as a classification: (1) the shape and size of basidiomycetes: the formation of the winter spore disease leaves placed in the petri dish moisturizing culture, with a microscope Observe the burden of falling spores. Previous taxonomic classification does not pay attention to spore, some rusty bacterium has special characteristics, such as Aster, Kalimeris genus of C.asterum host spores spherical
