CLASSIFICATION OF AGARICS 389 



gated, thickness variable, usually is nun. thick (rarely up to L5 

 mm. >, cylindrical, sometimes tapering upward, ;ii length Qexuous, 

 solid, white fibrillose-silky, soon pallid or tinged Fuscous, concolor 

 within, glabrescent. CORTINA white, persistent, rarely forming 

 an evanescent ring. BPORES elliptical, 10-11.5x6 micr., Bmooth, 

 pale ochraceons under the microscope. < > I >< > I J and TASTE mild. 



Solitary, scattered, rarely subcaespitose, deeply imbedded at base 

 of stem in sphagnum and mosses in balsam and tamarack swamp--. 

 North Elba, Adirondack Mountains, New York. Collection Kauff- 

 man. September, L914. Frequent. 



Variable in size of tap and thickness of stem bnl very distincl 

 from all other Cortinarii. The pair colors, the coiiic-cainpaiiuki te 

 cap, the sphagnum habitat ami the spores distinguish it. The type 

 specimens in Peck's herbarium appear to have been specimens of 



small size. Only the young rapidly developing plants show the 

 hygrophanous character well; they soon fade. Although the species 



is quite frequent in the swamps, I never saw a well developed an 



nulus nor definite si^ns of a universal veil, so that it appears to he 

 intermediate between Telemonia and Enoloma. Occasionally the 



stem is Bubclavate below. The gills are not dark at first in £ 1 



specimens and Peck may have had young, dry weather forms in 

 which the gills sometimes become dark prematurely. It would be 

 remarkable t<> find the young .nills "ferruginous-brown" as described 

 by Peck, in plants colored like this one. 



SUBGENUS DERMOCTBE: Pileus and stem neither viscid 

 nor hygrophanous. Pileus innately silky at first, glabrescent, flesh 

 thin. STEM equal or attenuated toward apex, stuffed t<> hollow, at 



Length slender, rather rigid or exterior. I'niversal veil rarely 

 present. 

 Composed <>f medium-sized or small, rather slender-stemmed ami 



often elegantly colored plants. The cortina is lihrillose. usually 

 of the same color as the pilens. Fries says "easily distinct from 



the [nolomas by the thinness and substance Of the pilens and by tlit- 

 stem." Several species, however, approach the subgenus Inohmia 



closely, especially those Dermocybes included under my first section. 

 The stem of the species of Dermocyhe is at length equal <>r attenu- 

 ated and this character combined with the small Bize and the lack 

 of distinct scales on the pilens. separates them from the BUbgenuS 



Enoloma. The absence of a truly hygrophanous pileus distinguishes 



them from the subgenus Ilydrocybe. which they simulate in size. 

 Some of the species are quite variable and many intermediate form-
