PILEUS 5-7 cm. broad, at first convex and subumbonate theu 

 depressed and finally entirely infundibuUform, dry, flaccid, coated 

 with a delicate silkiness, reddish to }n<h' Inn color, fading with age, 

 margin even and thin. FLESH white, thickish on disk. GILLS 

 deeply decurrent, close, thin, white or whitish, narrow, acuminate 

 at both ends, edge rather serratulate. STEM 4-8 cm. long, 5-10 

 mm. thick, tapering slightly upward, glabrous, spongy within, ex- 

 ternally firm, rather elastic, pale reddish or pallid, white-mycelioid 

 at base where attached to leaves, etc. SPORES ovate to sub- 

 pyriform, obliquely sharp-pointed and apiculate, 5-8 x 34 micr. 

 when mature, smaller when immature; basidia 1-spored. ODOR 

 pleasant, TASTE mild. 



(Dried: Cap reddish-tan, gills alutaceous to tan.) 



Single or somewhat caespitose. Attached to decaying leaves and 

 debris in both conifer and non-coniferous woods. Throughout the 

 State as far as Isle Royale. July-October. My first record is July 

 8, the last October 20. Very common. 



This is one of the first species to appear after the July rains set in. 

 It becomes very robust at times, simulating C. geotropa, but the 

 spores are longer than in that species. | See Patouillard, Tab. 

 Analyt.) The color of the cap changes in a definite direction; 

 when young and fresh the red color is predominant, when old the 

 whitish lines appear. O. flaccida Fr. is said to differ in the tawny 

 to rust-colored pileus which does not fade in age; I have been un- 

 able to recognize it in this State. The gills become yellowish. Its 

 shape and habit are like C. infundibuliformis, and are therefore 

 well shown in the illustrations of the latter. Both are edible and 

 not likely to he confused with any injurious mushrooms.
