August ( >cli)ltcr." 



The above description was made from specimens — « - 1 • t in me by 

 Q. I'. Morris in whose honor Peck earned it. The yellow color "f 

 the flesh, and the tendency of the cap and stem to become rustj in 

 age is a marked characteristic. The caps of dried specimens are 

 blackish-umber-brown. I have uol seen ii in Michigan. 



424. Cortinarius mammosus sp. QOV. 



PILEUS 2-8 cm. broad (mostly Mi cm.), conico-campanulate at 

 first, then expanded and obtusely umbonate, hygrophanous, fawn- 

 color to brownish-cinnamon, scarcely tinged with olivaceous, bud- 

 ferruginous on umbo when dry. beautifully silky-shining, glabres- 

 cent FLESH thin except on disk, concolor when moist, pallid when 

 dry. GILLS adnate, becoming emarginate, subventricose, medium 

 broad, close t«> somewhat subdistant, at "first />ulli<l with tinge of 

 fawn-color, then pale cinnamon-umber, edge even. STEM 5-9 cm. 

 long, tapering upward from a subclavate base <>r almost equal, 5-8

Differs from the similar species in the Dermocybe group, of which 

 C. cinnamomeus is the center, in its hygrophanous flesh, Lack of 

 yellowish gills and habit, as well as by the presence of the universal 

 veil. In this lasi respect it approaches C. sublanatus Pr. and C. 

 valgus Ft. (sense of Cooke), but is much more slender. The umbo 



is very obtuse and well developed from the first, and the gills are 

 not yellow nor saffron at any stage.
