It is quite common, often growing in large patches. Recent authors 

 agree upon the edibility and deliciousness of this species. The author 

 knows it to be one of the most plentiful, useful and delicious, after sev- 

 eral years of pleasant experience with it. 



In July, 1899, at Mt. Gretna, I found, growing from the ground gre- 

 gariously, a singular fungoid growth from 2-5 in. high; cap hemis- 

 pherical, i in. in diameter, tightly fitting a solid stem of nearly the 

 diameter of the cap. The whole was watery white, and evidently af- 

 fected by a parasite. It was edible. September ist Professor Peck 

 wrote to me : "I think I have found the identity of the diseased 

 Agaric, of which you sent me samples some time ago. I mean the one 

 affected by Hypomyces incequalis Pk. The host is Amanita rubescens, 

 at least sometimes, and probably always." 



The plant is very heavy for its size. The lack of a volva, the dingy 

 color and reddish stains .distinctly separate this from any poisonous 

 Amanita.
