Agaricaceae 



Amanita. In woods. Spring and summer. 



The Vernal Amanita scarcely differs from white forms of the A. 

 phalloides except in the more persistent and more closely sheathing 

 remains of the wrapper at the base of the stem. It is probably only a 

 variety of that species, as most mycologists now regard it, and it should 

 be considered quite as dangerous. I have not found it earlier than in 

 July, although in Europe it is said to appear in spring, as its name im- 

 plies. Peck, 48th Rep. N. Y. State Bot. 



Common over the United States. West Virginia, New Jersey, Penn- 

 sylvania, May to November. It appeared at Mt. Gretna, Pa., on May 

 28, 1899. Mcllvaine. 



The absence of a ring separates white forms of A. volvata and A. 

 vaginata. 



The virulence of its poison is the same as that of A. phalloides. 



A. magnivela'ris Pk. magnus, large; velum, veil. Pileus con- 

 vex or nearly plane, glabrous, slightly viscid when moist, even on the 

 margin, white or yellowish-white. Gills close, free, white. Stem long, 

 nearly equal, glabrous, white, furnished with a large membranous white 

 annulus, sheathed at the base by the appressed remains of the mem- 

 branous volva, the bulbous base tapering downward and radicating. 

 Spores broadly elliptical, iox6-8/x. 



PileilS 3-5 in. broad. Stem 5-7 in. long, 4-6 lines thick. 



Solitary in woods. Port Jefferson, Suffolk county. July. 



The species resembles Amanita verna, from which it is separated by 

 its large persistent annulus, the elongated downwardly tapering bulb of 

 its stem, and especially by its elliptical spores. Peck, 5oth Rep. N. Y. 

 State Bot. 



I have not seen this species. Its resemblance to A. verna is enough 

 to place the ban upon it until it has been tested. 



A. map'pa Fr. mappa, a napkin. From the volva. Pileus 2-3 in. 

 broad, commonly white or becoming yellow, slightly fleshy, convexo- 

 plane, obtuse or depressed, orbicular, dry, margin for the most part 

 even. Stem 2-3 in. long, 3-5 lines thick, stuffed then hollow, almost 

 equal above the bulb, rather smooth, white. Ring superior, soft, lax, 

 here and there torn. Volva regularly circularly split, somewhat ob- 

 literated ; the globose-bulbous base united with the stem, with an acute
