and umber-brown in the centre, beyond which it is clothed 
with small pilose scales. 
Stem 4 inches high, $ of an inch thick in the centre, 
attenuated upwards from the obtuse base, white, solid 
fibrillose. : 
Ring near the top of the stem torn, fugacious. 
Gills for a long time white, scarcely more than 1 line 
broad, attenuated behind, not ventricose, at length dark 
from the spores. 
Distinguished by its narrow white gills from A. campestris, 
and in its whole habit from A. arvensis. From A. cretaceus 
it is essentially distinguished by its stem not penetrating the - 
substance of the pileus, and consequently in its gills not 
being remote, and in its solid stem.
