Plate 16 



Cap 2-5 cm. broad, broadly campanulate, becoming expanded, 

 and at length nearly plane with the center a little prominent, pale tan 

 or pale rufescent at first, becoming white with age, glabrous, striate 

 on the margin when moist; flesh white, thin, especially on the margin; 

 odor when crushed strong and unpleasant. Taste disagreeable. 



Gills white, narrow, closely crowded, adnate with a distinct sinus. 



Stem 2-4 cm. long, 2-4 mm. thick, hollow, slightly enlarged at the 

 base, everywhere covered with white villous down, which is longer and 

 more marked at the base, the extreme base usually curved and 

 attached by an abundant white mycelium to the leaves in which it 

 grows. 



Spores 4-6 x 2.5-3 [jl. 



Somewhat gregarious, on old leaves in woods. 



This species appeared quite frequently in late summer at Asheville. 

 It is suggestive of C. confluens, and may easily be taken for it. As 

 found at Asheville it is more nearly white than C. confluens, has a 

 shorter stem, and is not inclined to occur in the dense clusters which 

 are characteristic of C. confluens. The rather disagreeable odor is 

 also a mark of distinction.
