Poisonous plants. 220 MANUAL OF POISONOUS PLANTS 16-20 II- in diameter; bad odor just before maturity and retaining the odor even in stored gram. Distribution and hosts. Common in eastern North America, also in Canada and Manitoba. Poisonous properties. It produces a bad odor when it occurs in flour and also gives the same a dark color and makes it unsalable. Tilletia Tritici (Bjerk.) Wint. Wheat Bunt Sori in the ovaries of wheat ovate or oblong, glumes spreading; spores chiefly spherical or sub-spherical; 16-22 /* in diameter, light to dark brown with winged reticulations. Infection of this and the preceding smut occurs at the time of germination of wheat, hence all of the stalks growing from the single wheat kernel become infected, mycelium growing upward with the growth of the plant. Distribution and hosts. Common upon wheat wherever cultivated. Re- ported as destructive and abundant in Michigan, Montana, and Kansas. Poisonous properties. Same as in the preceding species. Eubasidii Conidiophores with true basidia; reproduction generally asexual, sexual in some cases through the fusion of nuclei; spores cut off from the ends of the threads or borne on little sterigmata. The group is divided into two divisions according to the form of the basidia: Protohasidiomycetes, the rusts and gela- tinous fungi; Autobasidiomycetes, toad stools, mushrooms, and puff Fig. 59.
