THE WHITE-SPORED AGARICS 



27 



Amanita Frostiana. Pk. 

 Frost's Amanita. Poisonous. 



Frostiana, named in honor of Charles C. Frost. 



The pileus is convex, expanded, bright orange or yellow, warty, sometimes 

 smooth, striate on the margin, pileus one to three inches broad. 



The gills are free, white, or slightly tinged with yellow. 



The stem is white or yellow, stuffed, bearing a slight, sometimes evanescent, 

 ring, bulbous at the base, the bulb slightly margined by the volva. The spores 

 globose, 8-iOjn in diameter. Peck. 



Great care should be taken to distinguish this species from A. csesarea because 

 of its often yellow stem and gills. I found some beautiful specimens on Cemetery 

 Hill and on Ralston's Run. It is very poisonous and should be carefully avoided, 

 or rather, it should be thor- 

 oughly known that it may be 

 avoided. The striations on 

 the margin and its yellow 

 tinge might lead one to mis- 

 take it for the Orange Am- 

 anita. It is found in shady 

 woods and sometimes in 

 open places where there is 

 underbrush. June to Octo- 

 ber. 



Amanita verna. Ball. 



The Spring Amanita. 

 Poisonous. 



Verna, pertaining to 

 spring. This species is con- 

 sidered by some only a white 

 variety of Amanita phallo- 

 ides. The plant is always a 

 pure white. It can only be 

 distinguished from the white 

 form of the A. phalloides by 

 its closer sheathing volva 

 and perhaps a more ovate 

 pileus when young. 



The pileus is at first ovate, 

 then expanded, somewhat 

 depressed, viscid when
