This is one of our largest and most luxurious Hebelonias, appear- 

 ing after heavy rains. The stout, scaly-torn white stem, lack of 

 ,,,,, inn. broad gills and large spores, distinguish it. In age and 

 in we! weather il decays rapidly. Fries says it is solitary, but with 

 ns ii -icws in troops as described by Stevenson, often forming 

 dense rows along hillsides where Cortinarii flourish. Cooke's fig- 

 ures illustrate our plant well. It approaches H. sinuosum Fr. 

 I sense of Ricken).
