dingy rusty brown in age. Its habit is that of a stout-stemmed 

 C. rigens. The colors of the pileus when moist are " chestnut- 

 brown" to "cinnamon-rufous," and fade slowly; its texture is 

 rigid and brittle. The spores are small, 7-8 x 5 /x. 



CoRTiNARius INJUCUNDUS (Wcinm.) Fr. (Telamonia). Rare, 

 Leal. Under conifers. 



This belongs to the C. brunneus group and is about the same 

 stature and colors, but differs from C. brunneus in that the apex 

 of the stem, both within and without, as well as the young 

 gills, are violaceous; the gills are similar, but are attached with 

 a decurrent tooth; and the pileus is markedly variegated- 

 streaked in two shades of brown; the spores are about the same, 

 Barbier (Bull. Soc. Myc, 27: 183) considers it merely a form 

 of C. brunneus. Cooke's illustration, Plate 823, shows spores 

 which manifestly do not fit our plant. The spores of the Colo- 

 rado plants are broadly elliptical, 8-9 (10) x 6-7 /x. 



CoRTiNARius iSABELLiNUS Fr. (Hydrocybe). Frequent, 

 Leal, Tolland. In hard soil under pines. 



Characterized by its rigid-brittle stem and cap, with broadly 

 umbonate and usually gibbous pileus, which is umber when 

 moist, "olive-ochre" (Ridg.) when dry, and with thick and 

 rigid, rather broad gills. Pileus 3-5 cm. broad; stem 4-6 cm. 

 x 6-7 mm. thick and nearly equal. All parts on losing moisture 

 begin to show the !' olive-ochre" color, including the cortina. 

 The spores measure 8-9 (10) x 4.5-5 jjl. 



CoRTiNARius LANiGER Fr. Not infrequent. Tolland. Under 

 conifers. 



Its near relative, C. bivelus has a glabrous pileus, while in 

 this, the surface is at first and for a w^hile hoary-canescent, or 

 with appressed superficial silky-white fibrils, becoming glabrous 

 in time. Its spores are rather variable, 8-11 x 5-6 /jl. The 

 enlarged base of the clavate stem is quite tomentose-mycelioid 

 and sometimes quite villose upwards. 



CoRTiNARius LiLACiNiPES Britz. (Bulbopodium). Infre- 

 quent, Leal. Under spruce and fir. 



The narrow, crowded gills, at first " vinaceous-fawn" (Ridg.) 

 in color, the lutescent bulb attached to an ochraceous mycelium,
