Differs from the preceding, for a variety of which il 

 may easily be taken, by the more regular pileus, 2 to 4 

 lobed, scarcely laciniate, lobes later becoming free, and 

 especially by the colour. The stature generally smaller, 

 afterwards becomes equally as tall as Helvetia mitra, g. 

 "pratensis A. and S. Although, therefore, acute characters 

 are wanting in nature, it is constant ; it is also inferior 

 in cooking (Fries, I. a). 



Name — Lacunosus, full of holes; from the pitted 

 pileus.
