This species, it is sai<l. is to be looked for among grass in 

 meadows, etc., bn1 the writer has nol found it in such localities. The 

 description applies to the American form, which is usually smaller, 

 its rap is rarely distinguished by rimose cracks, and the spores are 

 smaller than given for the European plant. The recorded European 

 spore-measurements vary from 8-10 x 5 t<> 10-12 s6-7 micr. < >ur plant 

 is probably a distinct variety if not a species. It has also closer 

 gills than the type. It is hard to distinguish from the pallid variety 

 of //. pratensis except for its narrower spores, and lew ambonate 

 or turbinate pileus, which is commonly pure white.
