THE WHITE-SPORED AGARICS 



109 



Collybia platyphylla. Fr. 



Broad-Gilled Collybia. Edible. 



Platyphylla is from two Greek words meaning broad and leaf, referring to 

 the broad gills. It is a much larger and stouter plant than Collybia radicata. It 

 is found in new ground on open pastures about stumps, also in woods, on 

 rotten logs and about stumps. 



The pileus is three to 

 four inches broad, at first 

 convex, then expanded, 

 plane, margin often up- 

 turned, smoky brown to 

 grayish, streaked with 

 dark fibrils, watery when 

 moist, flesh white. 



The gills are adnexed, 

 very broad, obliquely 

 notched behind, distant, 

 soft, white, in age more 

 or less broken or 

 cracked. 



The stem is short, thick, 

 often striated, whitish, 

 soft, stuffed, sometimes 

 slightly powdered at the 

 apex, root blunt. The 

 spores are white and 

 elliptical. 



It is easily distinguished 

 from C. radicata by the 

 blunt base of the root and 

 the very broad gills. Like 

 C. radicata they need to 

 be cooked well or there 

 is a slightly bitter taste 

 to them. They are found 



from June to October. Figure 7 9--Collybia platyphylla. One-third natural size.
