SOME COLORADO FUNGI* 



L. O. OVERHOLTS 



Except for a considerable number of papers on parasitic fungi, 

 very little literature dealing with the fungous flora of the western 

 states has yet appeared. As a matter of fact a prodigious amount 

 of work is necessary before the fungi of any large section of the 

 United States can be accurately catalogued. As a means to this 

 end carefully prepared check lists are invaluable, provided the 

 specimens and notes on which they are based are adequately pre- 

 served. Such lists are also of some value to local collectors, both 

 in aiding them in their determinations and in stimulating more 

 widespread interest in collecting and preserving the specimens. 



The writer spent parts of the summers of 191 3 and 1914 at 

 the Mountain Laboratory of the University of Colorado for the 

 purpose of collecting the fleshy and woody fungi of that region. 

 Through the efforts of Dr. Francis Ramaley, Professor of Botany 

 in the University of Colorado, a certain amount of financial assist- 

 ance was obtained from that institution in return for a duplicate 

 set of the specimens collected. These are, therefore, deposited in 

 the herbarium of that University. The most complete set of 

 specimens is retained in the writer's herbarium. Duplicates of 

 some of the collections are in the herbarium of the Missouri 

 Botanical Garden and the New York Botanical Garden. 



The Mountain Laboratory of the University of Colorado is 

 located in the town of Tolland, in Gilpin County, Colorado. 

 This town lies on the Moffatt Railroad 47 miles northwest of 

 Denver, and on South Boulder Creek. South Boulder Park, in 

 which the town lies, has become well known to botanists through 

 the writings of Dr. Ramaley, Professor W. W. Robbins, and 

 others interested in the ecology of the eastern slopes of the 

 Rocky Mountains. It lies at an elevation of practically 9,000 feet
