THE FUNGUS FLORA OF MT. HOOD, 

 WITH SOME NEW SPECIES* 



C. H. KAUFFMAN 



TOURING the autumn of 1922, the writer, accompanied by- 

 Mr. L. E. Wehmeyer, collected and studied the fungi in a small 

 area at the western base of Mt. Hood. By the advice and 

 through the kindness of the men of the Portland Office of the 

 United States Forest Service, accommodations were obtained at 

 the ranch-house of Mr. and Mrs. W. J. Faubian, just inside the 

 western entrance to the Oregon National Forest, and on the 

 first lap of the Mt. Hood Highway. For numerous courtesies 

 extended by the men of the Portland Forestry Office, the writer 

 wishes to make grateful acknowledgment. 



The foothills rise in abrupt ridges at this point, and repre- 

 sent a portion of radiating outposts of the great mountain peak 

 visible beyond. Near by two of the valleys are well watered by 

 the Zigzag River and the Sandy River, with their sources in 

 the glaciers and snow-fields about twelve miles from our station. 

 Smaller streams also abound. Some of the valleys and ridges are 

 still covered by forests of Douglas fir, western hemlock, white fir, 

 some scattered cedars, and in low places two species of maple and 

 one of alder. The topography and water-relations are such as to 

 produce a variety of habitats favorable to fungi of all sorts, and 

 as the rainy season was well started when we arrived, it was not 

 surprising that within the single month of our stay a large mass of 

 material came to hand. The collecting was started on Septem- 

 ber 21 and terminated October 24. The area covered was 

 scarcely more than a two- to three-mile radius from the ranch.
