Redescription. Pileus somewhat fleshy in the middle, 4-7 cm 

 broad, top-shaped to nearly plane or considerably depressed in the 

 middle, brownish gray to blackish or smoky gray, surface dry, 

 margin somewhat irregular not inclined to be reflexed in drying. 

 Flesh white, thin, not stained with age or drying. Gills decurrent, 

 thick, blunt on the margin, up to 5 mm in width, sparingly dicho- 

 tomously branched, distant, at first whitish becoming with age and 

 on drying distinctly buff colored, conspicuously intervenose espe- 

 cially toward the margin. Stem 4-6 cm long, 5-10 mm thick, 

 usually somewhat upwardly attenuate, glabrous-striated, pallid or 

 grayish or smoky, but distinctly paler in color than the pileus, and 

 white at the base, hollow in the Oneida specimens, apparently solid 

 or stuffed in the type. Spores white in mass, broadly elliptical, 

 7—8 X 3—4 micr. 



Peck's type collection of this species consists of two distinct 

 things. As he pointed out in the original description " two forms 

 are distinguishable." The ones with " lamellae slightly rounded 

 behind and adnate or abruptly terminated " is apparently C 1 i - 

 t o c y b e c 1 a v i p e s , at least the gills are closer and not inter- 

 venose. As to color we can not judge very accurately from the 

 dried specimens but the colors must have been approximately the 

 same as in C. m e d i a or he would not have confused them. 



I take as the type of his C 1 i t o c y b e media, those larger 

 specimens of the original collection which show the characters upon 

 which in the description he lays so much stress, namely, the inter- 

 venose character of the subdistant decurrent gills. 



The specific name media was given to this by Peck because of its 

 apparent position between two other species of Clitocybe. As a mat- 

 ter of fact jt is very unlike any other species of Clitocybe, but the 

 name media is still appropriate because the plant appears when fresh 

 to be as properly a species of Cantherellus as of Qitocybe.
