Mycological Flora of the Rockies 131 



proaches C. prasinus in its colors, but with less green. It differs 

 from C. virentophyllus in spores, colors and habitat. When 

 quite young, the green shades are more manifest. In wet 

 weather, the bulb is viscid from the veil-remnants. The cor- 

 tina is at first attached to the margin of the bulb, thus indicat- 

 ing its position in the subgenus Bulbopodium. 



CoRTiNARius COLYMBADINUS Fr. (Dermocvbe). Very com- 

 mon in a restricted area of spruce and fir forest. Leal. 



This is form (B) of Fries's Monographia, which he collected 

 under pines. When it is moist and drying, the subhygrophanous 

 character is apt to lead one into the hygrophanous groups. The 

 "tawny-olive" to "old-gold" (Ridg.) color of the moist cap, the 

 tendency of the margin to become geniculate, the rather broad, 

 almost subdistant gills and spores which measure 7-8 (9) x 6-6.5 

 )U, separate it from its allies. This form had only a slight radish 

 odor, while form (A) of Monographia, which occurred under 

 beech, is said to have had a very strong odor of radish. 



CoRTiNARius CROCEOCONUS Fr. Rare. Leal. Mossy ground 

 under conifers. 



CORTINARIUS CYANOPUsFr. Rare, Leal. Under spruce and fir. 



This seems to agree well enough with the conception handed 

 down to us. The spores measure 10-12 x 8-9 /jl. It is Ricken's 

 plant, except that both he and Fries limit it to frondose woods. 

 Since its violet-stemmed allies are already numerous, I refrain 

 from segregating it on such slight grounds. C. aggregatus Kauff. 

 has much smaller spores. Further study of these violet species 

 may bring out additional useful characters. The gills of the 

 Colorado plant were "deep vinaceous-la vender " (Ridg.) at first, 

 and their edge noticeably crenulate. The upper part of the 

 stem within and without had the color of the young gills. The 

 pileus was "cinnamon-buff" to "clay color" (Ridg.). 



CORTINARIUS CYLiNDRiPES Kauff. (Myxacium). Infrequent. 

 Tolland. In moist places under conifers. 



CORTINARIUS DECUMBENS Fr. (Dcrmocybe). Rare. Leal. 

 Under spruce and fir. 



The whole plant is at first "ivory white" (Ridg.), later the 

 gills become "Sayal-brown" from the spores. The specimens
