摘要:

SUMMARYSome evident cases of synonomy in certain graminicolous smut fungi are presented and desirable consolidations are recommended.Ustilago nigra, U. Avenae, andU. perennans, causing dark brown to black loose smuts of barley, oats, and tall oatgrass, respectively, are considered as specialized varieties of a single morphologic species, which, according to International Rules of Botanical Nomenclature would bear the nameU. AvenaealthoughU. nigrawould be more descriptive.It is recommended that the covered smuts of barley and of oats,Ustilago HordeiandU. Kolleri, respectively, be considered as specialized varieties of a single morphologic species, which by priority would be calledU. Hordei.Emphasis is given to earlier proposals thatUstilago TriticiandU. nuda, causing loose smuts of wheat and of barley, respectively, be considered as specialized varieties of the same morphologic species, which by priority would bear the nameU. Tritici.Urocystis Agropyri, U. Tritici, andU. occulta, causing flag smuts of grasses, wheat, and rye, respectively, are shown to be very similar in morphology and in the effect on the host plants. In fact, the first two are considered identical, and it is recommended that they be consolidated under one name, which by priority would beU. Agropyri. Urocystis occultaseems to have one fairly constant distinguishing morphologic character in that the spore balls are more or less incompletely invested by the sterile cells, and at present it seems preferable to retain it as a separate species.
