=Amanita virosa= Fr. =Deadly Poisonous.=--This plant also by some is regarded as only a form of _Amanita phalloides_. It is a pure white plant and the pileus is viscid as in the _A. verna_ and _A. phalloides_. The volva splits at the apex as in _A. verna_, but the veil is very fragile and torn into shreds as the pileus expands, portions of it clinging to the margin of the cap as well as to the stem, as shown in Fig. 62. The stem is also adorned with soft floccose scales. Gillet further states that the pileus is conic to campanulate, not becoming convex as in _A. verna_ and _A. phalloides_. The variability presented in the character of the veil and in the shape of the pileus suggests, as some believe, that all these are but forms of a single variable species. On the other hand, we need a more careful and extended field study of these variations. Doubtless different interpretations of the specific limits by different students will lead some to recognize several species where others would recognize but one. Since species are not distinct creations there may be tolerably good grounds for both of these views. [Illustration: FIGURE 62.--Amanita virosa, white (natural size). Copyright.] =Amanita floccocephala= Atkinson. =Probably Poisonous.=--This species occurs in woods and groves at Ithaca during the autumn. The plants are medium sized, 6--8 cm. high, the cap 3--6 cm. broad, and the stems 4--6 mm. in thickness. The =pileus= is hemispherical to convex, and expanded, smooth, whitish, with a tinge of straw color, and covered with torn, thin floccose patches of the upper half of the circumscissile volva. The =gills= are white and adnexed. The =spores= are globose, 7--10 µ. The =stem= is cylindrical or slightly tapering above, hollow or stuffed, floccose scaly and abruptly bulbous below. The =annulus= is superior, that is, near the upper end of the stem, membranaceous, thin, sometimes tearing, as in _A. virosa_. The =volva= is circumscissile, the margin of the bulb not being clear cut and prominent, because there is much refuse matter and soil interwoven with the lower portion of the volva. The bulb closely resembles those in Cooke's figure (Illustrations, 4) of _A. mappa_. Figure 63 shows these characters well. [Illustration: FIGURE 63.--Amanita floccocephala (natural size). Copyright.] =Amanita velatipes= Atkinson. =Properties Unknown.=--This plant is very interesting since it shows in a striking manner the peculiar way in which the veil is formed in some of the species of _Amanita_. Though not possessing brilliant colors, it is handsome in its form and in the peculiar setting of the volva fragments on the rich brown or faint yellow of the pileus. It has been found on several occasions during the month of July in a beech woods on one of the old flood plains of Six-mile creek, one of the gorges in the vicinity of Ithaca, N. Y. The mature plant is from 15--20 cm. high, the cap from 8--10 cm. broad, and the stem 1--1.5 cm. in thickness.
