CLASSIFICATION OF AGARICS 397 



Swedish specimens collected by myself. These have spores measur- 

 ing 7-8.5x4-5.5 micr. The following Bpecies seems closely related 

 but differs in the spore character. 



402. Cortinarius cinnamomeus l'r. var. 

 Illustration : Cooke, III.. PI. 778 (as 0. dnamomeua var. i. 



PILEUS 2-6 cm. broad, campanulate or subhemispherical, obtuse 

 or discoid, ombonate, regular at first, then wavy-margined, olwo- 

 ceous-cinnamon-brown, tinged nitons on disk, innately and minutely 

 fibrillose-scaly or silky, edge incurved. FLESB yellowish white. 

 rather fragile. GILLS adnate, narrow, close to crowded, cadmium 

 yellow with olivaceous tint, thin, eroded-crenulate on edge. STEM 

 5-9 cm. long, 1-7 mm. thick, slightly enlarged below and tapering 

 upward, fibrillose-striate, pale yellow, olivaceous-tinged, becoming 

 tubular, yellowish-olivaceous within. CORTINA yellow, fibrillose. 

 SPOKES elliptical, smooth, 7-9 x 4-."> micr. ODOR and TASTE mild. 



Gregarious. Among mosses in a sphagnum swamp. Bay View, 

 Ann Arbor. August-September. Infrequent. 



Differs from ('. cinnamomeus in the rufous cast on the pileus, the 

 narrow gills, suhclavate stem and slightly Longer spores. It is well 

 represented by the figure of Cooke cited above. Variety croceus is 

 smaller, gills less crowded, gills and stem tinged olivaceous. (See 

 Cooke, ill., PL ~Si). | 



403. Cortinarius croceoconus Fr. 

 Monograph ia, 1851 . 



PILEUS L-3 cm. broad, obtusely conico-campanulate, umbo per- 

 sist inn-, tirm, rufous-fulvous to ful vous-cinna mon . silky, dry, even. 

 subshining, margin incurved. FLESH whitish, tinged red at the 

 upper surface, yellowish toward stem, thick at umbo, thin elsewhere. 

 GILLS adnate then somewhat seceding, ascending, rather narrow, 

 close, pale yellow at first, then cinnamon, opaque, edge minutely 

 eroded. STEM elongated, 5-12 cm. long, 3-5 nun. thick, equal, 

 flexuous, fibrillose with rufous-fulvous fibrils, yellowish within, elas- 

 tic, stuffed then tubular. CORTINA pale rufous-fulvous, becoming 

 pallid, subfibrillose. SPORES elliptical, almost smooth. 8-9.5x5 

 micr.
