Amanita calyptrata albescens Pk. Rep., 1899: 840. Sandy soil, 

 Gansevoort, Saratoga county, New York. July. Our specimens differ 

 from the typical form of the species (A. calyptrata Pk. see page 26) in 

 being wholly white or whitish. The 

 type (A. calyptrata) which was sent 

 from Oregon, has the pileus yellow 

 or yellowish brown, and the lamellae 

 yellowish white, both having a slight 

 tinge of green. The peculiar thick, 

 felty, white fragment of the volva 

 that adheres to and covers the central 

 part of the pileus forms a characteris- 

 tic feature of the species and is sug- 

 gestive of its name. This, together 

 with the thick remains of it at the base 

 of the stem, and the more strongly 

 striate margin of the pileus, easily 

 distinguishes the species from A. 

 spreta, to which it is closely allied. 

 Because of its different color I have 

 considered our plant a variety of the 

 species and named it variety albescens. 



The Oregon plant (A. calyptrata) 

 is known to be edible, but as only two specimens of the variety were 

 found, no opportunity for testing its edible quality was given. Peck. 



Amanita Frostiana pallidipes Pk. Rep., 1899: 855. The typical 

 form of this species, which is common in our cool northern woods, has 

 the pileus and annulus, and usually the stem also, of a yellow color, 

 that of the pileus sometimes verging to orange. But in warmer and 

 more open or bushy places forms occur in which the whole plant is 

 whitish, but in other respects has the characters of the species. Some-
