On the ground. 



Somewhat resembling 0. iimhellifera^ but distinguished by 

 the gills being narrowed behind.* 



On sterile heaths and damp uncultivated places. Stem 

 stuffed, short, J in. long, rarely more, \ line thick, equal or 

 slightly incrassated upwards and also often hollow, polished 

 glabrous, brown then grey, base rather downy ; pileus mem- 

 branaceous, disc always truly and broadly umbilicate, the 

 rest distinctly arched, up to J in. across, striate when moist, 

 brown then grey, even when dry ; in some forms glabrous 

 and becoming brownish, in others somewhat silky and hoar}' ; 

 in the first form, which appears to be the young stage, the 

 gills are adnate and brownish, slightly, and in the second 

 form dee^Dly decurrent, rather distant in both, arcuate, 

 broadest in the middle. Quite distinct from 0. iimheUifera.

Very much resembling 0. jyyxidata, but differing in being 

 rather coriaceous, even margin of pileus, and absence of
