 stem being at first short and flocculose, then elongated and 

 glabrous. 



Stem more or less hollow, at first with a central pith, 

 short (1 in.), hairy flocculose, then elongated and almost 

 smooth, shining, 1 line thick, attenuated upwards, and 

 there mealy. Veil scarcely evident. Pileus rather fleshy, 

 hemispherical, then expanded, umbonate, 1 in. broad, even, 

 glabrous, scarcely viscid, yellowish-rufous. Gills arcuato- 

 decurrent, broad, crowded, livid then brown. (Fries.)
