1921] The Collybias of North Carolina 95 



3276. On a rotting oak stump in Battle's Park, June 1, 1919. A remarkable form 

 of C. platyphylla. Cap drooping with the margin crimped inward, 

 about 11 cm. across below, and hanging down about 10 cm., glabrous, 

 but cracked into inherent scales over all but margined half or third. 

 Stem very long, 24 cm., 1.7 cm. thick; fibrous, tough. Spores smooth, 

 ovate, 5.9-6.6 X 7.7-8. l/z.

Plate 14. 



Cap 2-4 cm. broad, rounded convex to broadly campanulate, with 

 the center a Uttle prominent; hygrophanous, yellow, with the disk 

 often reddish or brownish, minutely fibrillose; margin thin, exceeding 

 the gills, even. 



Gills yellow, close; narrow, sinuate adnexed, usually turning red in 

 drying. 



Stem slender, 2-4 cm. long, 3-5 mm. thick, colored like the cap, 

 hollow, glabrous. 



Spores ellipsoid, 4-6 x 3-3.5 [x. 



On old logs; not rare. 



This is without question Peck's C. colorea. Our specimens have 

 been submitted to Bresadola and approved as C. exsculpta, which is 

 said to be rare in Europe. The gills usually change to red in drying, 

 but I have had undoubted specimens in which this is not the case. 

 Occasionally I have found specimens in which the growing plant were 

 red. This, I take it, is Feck's Yav.ruhescentifolia. From the pecuhar 

 color and its habit of growing on logs this species would be taken at 

 first sight for Flamrnula.
