Scolecotrichum grammis, Fuckel Elongated brown or purplish-brown spots, the centers of which are gray or whitish and contain minute black dots; these small dark spots contain the tufts of brown fungus threads, which make their way out through the stomata; the hyphae are somtimes septate and the spores are usually borne at the end or occasionally in a lateral position; these fruiting hyphae bear small, smoky- brown, two-celled spores; the cells of the leaf become much altered, because the colorless threads of the fungus permeate them. On barley the disease is marked by brown or purplish-brown spots which appear on the leaf transversely. Distribution. Widely distributed in Europe and North America. Poisonous properties.
