Amongst grass, moss, &c. 



Somewhat variable, but always small, and readily dis- 

 tinguished by the yellow pileus and stem being slightly viscid. 



It is doubtful whether the figure given by Cooke and 

 quoted above, represents the present species, as pileus, stem, 

 and flesh are , represented of a uniform, pale reddish-brown ; 

 gills tawny, subdecurrent. 



*** Gills adnate, pileus campanulate, then expanded. 



Naucoria nucea. Bolton.

 curved, pale chestnut;, gills narrowed behind, adnate, 

 ascending, rather crisped, cinnamon ; stem about 3 in. long, 

 1| lines thick, silky-fibrillose, white ; spores elliptical, baso 

 apiculate, 10-11 x 6 /x.

On the ground amongst firs, &c. 



The root is a hard tubercle, furnished with fibres of a 

 mouldy grey colour. 



The stem is upright; fistular, of a pale dead white, and 

 about the thickness of a crow's quill near the root, growing 

 gradually smaller upwards ; the height is about four inches, 

 the substance thin, tender, and easily splitting in small 

 shining filaments. 



The gills are arranged in three series ; they are broad and 

 thin, gently waved on the edges, and touch not the stem 

 with their base ; the substance is thin and delicate, and the 

 colour a pale pretty brown.
