THE MYCOLOGICAL FLORA OF THE HIGHER 

 ROCKIES OF COLORADO 



C. H. KAUFFMAN 



In 1917 the writer, accompanied by his wife, spent the 

 month of August at Leal, Grand County, collecting and study- 

 ing the fungi of that vicinity.^ Leal Post-Office is the last ranch 

 at the upper end of the valley through which runs Williams 

 Fork Creek. This station is within the shadow of Ute Peak 

 and of the Williams Fork Mountain range on one side, and the 

 slopes leading to the Continental Divide on the other. At this 

 point the stream is forked, with the two tributaries forming 

 moist, narrow valleys up which much of the collecting was done. 

 The elevations covered varied between 9,000 to 10,000 feet. 

 The surrounding forest is a part of the Arapahoe National For- 

 est. It consists principally of lodge-pole pine, sparsely inter- 

 spersed with Engelmann spruce, while the higher portions are 

 characterized by thick stands of subalpine fir. Aspen is scat- 

 tered over the lower openings. 



In 1920 a second trip was undertaken, this time to the east- 

 ern slope of the Continental Divide, in the region around Tol- 

 land, Gilpin County. On this occasion, Mr. Frank B. Cotner 

 and Mr. Dow Vawter Baxter, two students from our laboratory, 

 offered their services, and assisted in a survey of this area dur- 

 ing the month of September. Mr. Baxter paid special atten- 

 tion to the rust flora, while Mr. Cotner collected Discomycetes. 

 Unfortunately, Mr. Cotner was called home in the middle of the 

 month, thus reducing the party to two. 



A cabin was rented about a mile east of Tolland and excur- 

 sions made up the streams in all directions. The region is well 



1 A grant of one hundred dollars was given the writer by the American 

 Association for the Advancement of Science, to help defray the expenses 

 of this trip.
