Paxillus 



Cap symmetrical or excentric, edge persistently incurved ; gills 

 decurrent, separating readily from the flesh of the cap ; stem central, 

 excentric or lateral.

 of the cap. 



P. Icpista. — Cap 2-5 in. across, soon plane or depressed, edge 

 strongly in\-olute, dingy white ; gills very narrow, crowded, de-
