PILEUS 2-6 cm. broad (rarely 7) pliant, convex-plane, depressed, 

 at length often concave-subinfundibuliform with elevated margin, 

 margin at first involute at length undulate, orange-ocltraceus to 

 brownish-orange, sometimes pale, subtomentose or subsquamulose 

 on disk, even. FLESH soft, somewhat thick, thin on margin, pallid 

 or tinged ochraceous. GILLS arcuate-decurrent, thin, edge blunt, 

 dichotomously forked, crowded, rather narrow, not ridge-form, 

 bright orange or tinged with salmon-color. STEM 3-5 cm. long, 

 4-10 mm. (or more) thick, spongy, thickened downwards, or sub- 

 equal, stuffed sometimes hollow, minutely tomentose, pale orange 

 varying brownish or pallid-yellowish. SPORES elliptical, 5-7x3-4 

 micr., smooth, whitish in mass. ODOR and TASTE mild. 



Gregarious, on the ground, much decayed logs or wood, among 

 debris, in conifer and frondose woods, more abundant northward. 

 Throughout the state. July-October. Frequent. 



Distinguished from C. cibarius by its thin, crowded gills and 

 orange colors. A form occurs with pale yellowish-white cap ami 

 stem ; this I have seen in Sweden where it is more common than 

 with us. Fries says a white form also appears. It is marked pois- 

 onous or suspected by many European authors, although Peck, Mc- 

 Ilvaine and others have eaten it without bad results, but the flavor 

 is said to be poor. It occurs mainly in conifer woods but also in 

 low frondose woods, perhaps where tamarack once grew.
