luteous, margin sterile and slightly incurved; flesh yellowish, 

 of pleasant odor but bitter taste; gills adnexed to somewhat 

 decurrent, yellowish to deep ferruginous; spores ellipsoid, fer- 

 ruginous, 9 X 5 /*; stem 5-7 X 0.6-1 cm., solid, firm, ventricose, 

 fibrillose, concolorous below, nearly white above ; ring rather 

 large and conspicuous, soon colored by the copious spores. 



This species is very handsome, occurring in conspicuous clus- 

 ters on dead trunks in woods from August to October. Although 

 separated from the European species Pholiota spectabilis by 

 Professor Peck in 1898, it is very closely related to that species 

 and might be considered only a variety of it by some authorities. 

 Both species are considered very rare in this country. The illus- 

 tration was made from specimens collected near Bronx Park by 

 Mr. E. C. Volkert, September 24, 1908, and determined by Pro- 

 fessor Peck. Another specimen was brought in last fall from 

 Forked River, New Jersey, by Mr. W. H. Ballou. 



Amanitopsis vaginata (Bull.) Roze 

 Sheathed Amanitopsis 



Plate 7. Figure 5. X £ 



Pileus thin, fragile, companulate to expanded, 3-8 cm. broad; 

 surface dry, glabrous, deeply striate on the margin, exceedingly 

 variable in color, ranging from nearly white to reddish-brown; 

 gills free, fragile, white; spores globose, smooth, hyaline, 8-10 fx; 

 stem nearly equal, scarcely enlarged below, glabrous or adorned 

 with minute scales, variable in color, hollow or stuffed within, 

 6-12 cm. long, 4-8 mm. thick, entirely devoid of a ring, but con- 

 spicuously sheathed at the base with a long, loose, white volva, 

 portions of which are sometimes carried up as patches on the cap. 



This attractive and very variable species is abundant in woods 

 throughout Europe and North America during summer and 

 autumn, and possesses excellent edible qualities. It may be dis- 

 tinguished from species of Amanita, some of which are deadly 

 poisonous, by the total absence of a ring on the stem, although 

 the conspicuous volva at the base suggests its close relationship 

 to that genus. The variations in color presented by this species 

 are often very bewildering to the beginner.
