known to botanists as the location of the mountain laboratory 

 of the state university of Colorado. 



This station was barely twenty-five miles, as the crow flies, 

 from the one at Leal on the west side of the Divide. Its topog- 

 raphy and flora have been discussed by a number of writers. 

 (See Literature: 1, 4, 5, 6, 7, 10.) 



The forests present and the elevations covered were about 

 the same as at Leal. The rains had been abundant during Au- 

 gust, and a copious crop of fungi, especially agarics, had fruited 

 and many of these apparently did not again appear dur- 

 ing September. The August crop was still in evidence when 

 the party arrived, but was largely gone before it could be 

 studied. This was especially true of the Cortinarii, which must 

 have been very plentiful in August, but were comparatively 

 rare in September. At Leal, tHe Cortinarii were astonishingly 

 plentiful in August. In other parts of the LTnited States, no 

 such general fruiting of Cortinarii was observed until later in the 

 season, although fruiting varies more or less with the weather 

 conditions of any season. 



Two papers have recently appeared, listing fungi from Col- 

 orado. Seaver (8) gives an account of the Discomycetes, many 

 of which were collected at Tolland by Professor Bethel and 

 himself, during August and September, 1910. Overholts (3) 

 spent portions of the two seasons of 1913 and 1914 at Tolland; 

 his lists include all the principal groups of fungi. It was the 

 initial intention of the writer to explore a different portion of 

 Colorado, but circumstances interfered, and Tolland was selected 

 instead. Duplication has, therefore, resulted, but on the other 

 hand, new material was obtained to justify the time spent in 

 this region. 



The identifications were made largely by the writer. He 

 is under obligations to Dr. E. B. Mains for an examination of 

 all the Rusts; to C. G. Lloyd for opinions on some specimens 

 sent him; and to Dr. L. 0. Overholts for information on the 

 identity of some Porias. The Myxomycetes were identified by 

 May V. Cannon of our Herbarium. In some cases, the writer 

 of this paper has, nevertheless, followed his own judgment, and
