Amanita calyptrata Pk. 



PLATE A, fig. 1-5 



Sandy soil. Gansevoort, Saratoga co. July. Our specimens dif- 

 fer from the typical form of the species in being wholly white or 

 whitish. The type, which was sent from Oregon, has the pileus yel- 

 low or yellowish brown, and the lamellae yellowish white, both hav- 

 ing a slight tinge of green. The peculiar thick, felty, white frag- 

 ment of the volva that adheres to and covers the central part of the 

 pileus forms a characteristic feature of the species and is suggestive 

 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 . s p r e t a, 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 is known. to be edible, but, as only two specimens of the variety 

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



Amanita multisquamosa sp. 



PLATE B, fig. J-J 



Pileus convex, becoming nearly plane, even or but slightly striate 

 on the margin, adorned with numerous angular, erect, persistent but 

 separable warts, white or white with a brown or brownish center, flesh 

 white ; lamellae close, free, white ; stem equal, glabrous, stuffed with a 

 webby pith or hollow, bulbous at the base, white, annulus white, per- 

 sistent, the bulb more or less margined above by the remains of the 

 volva ; spores subglobose or broadly elliptic, .0003 to .0004 of an inch 

 long, .00024 10 -0003 broad. 



Pileus 2 to 4 inches broad ; stem 1.5 to 4 inches long, 3 to 6 lines 

 thick. Woods and groves. Albany, Rensselaer and Suffolk counties. 

 July. 



The species has the volva definitely circumscissile, and after its 

 rupture the free margin sometimes closely sheathes the base of the 

 stem. In some of the specimens the central part of the pileus is 

 areolate rimose, a wart occupying the center of each areola. The 

 warts are more closely placed in the center than toward the margin. 

 From pale forms of A . muscaria this species may be separated 

 by its more crowded, angular, erect warts and by the absence of 

 scales or fragments of the volva from the base of the stem.
