 Cke., Illustr., pi. 1058.

Smell none. Readily distinguished by the pale ochrace- 

 ous straw-colour of every part, and the intensely acrid taste. 

 The gills sometimes exude drops of water in damp weather. 



Superficially resembling B. ocliracea, but readily distin- 

 guished by the very acrid taste.

 yellow beneath the cuticle; convex, at first bullate, then 

 plane, slightly depressed in the centre, deep chrome-yellow, 

 margin turned down, at length patent, even or slightlj- 

 striate when old, often paler than the disc, but sometimes of 

 a deeper colour, cuticle not easily separable ; gills scarcely 

 crowded, adnexed and narrowed behind, not united behind,
