CAT-TAIL GRASS FUNGUS. 423 Kansas and other parts of the West; but on investigation it was found that the sloughing of the hoofs and other symptoms were the result of ergotism, due to the foul hay on which the cattle had been fed. Similar cases have occurred in other parts of the country, and in Europe the use of flour made from ergotized grain has occasionally given rise to epidemics of a similar nature among men. However it may be as regards abortion, ergot does not usually occur abundantly enough in closely grazed pastures to cause this trouble. It has been suggested that it may be pre- vented from occurring to a dangerous extent in hay by cutting grass as soon as it comes to bloom, and curing it before the ergot has matured. Yellowish-white, irregularly rounded bodies, with a checked surface, occurring in the flowers of Paspalum laeve, are >Spermoe- dia paspali (Fr.), the sclerotium of an entirely different fungus. 6. Cat-tail grass fungus, {EpichVOe typhina, P.). Forming a white or yellow coating around the upper leaf-sheaths of grasses. This pretty fungus is found on rather young plants through the entire open season. The veivety-ring which it forms about the sheath consists at first of a loose mycelium, rooted in the tissues of the grass, which bears an abundance of conidia, or summer-spores, by which other plants are infected. As the season goes on this thickens into a yellow or waxy mass, while its surface becomes uneven by the elevation of minute points, each containing, when ripe, a cluster of asci, or spore-sacs, filled with spores. In Europe, meadow grasses, and especially Timothy, are some-. Fio. 167.—£ptc/iU}e on shoath of grass, with enlarged fruits.. Please note that these imag
