Abstract

This paper is based largely on a study of grass disease specimens obtained in the Far West. A few noteworthy collections were made in June and July, 1957 in the Priest River and Priest Lake areas in Idaho and in adjacent Pend Oreille Co., Washington. Some specimens were gathered in the mountains of north central Washington in August of 1957. Many packets were obtained in late August and early September in company with G. W. Fischer in the mountains of Oregon, California, Nevada, Arizona, Utah and Idaho. Owing to opportune rains in northern Arizona, the collecting in the vicinity of Flagstaff was especially rewarding. Only part of the late summer material will be discussed here; the remainder awaits later study. Unless otherwise mentioned, all material gathered in August and September, 1957, was collected by Fischer and the writer and filed with a WSP number in the Plant Pathology Herbarium, Washington State College, Pullman, C. G. Shaw, Curator.
