Murrill: Amanitas of Eastern North America 85 
mentions the presence of a veil. Other parts of the description, 
such as the “ radicate stipe ” and the “ warty pileus ” make it 
pretty clear that the plant is only a form of V encnarius solitariiis. 
Amanitopsis hyperborea P. Karst. Hattsv. i : 7. 1879. Re- 
ported from Greenland by Rostrup (Med. Groenl. 3; 528. 1888), 
but I have not seen it among American collections. 
Agaricus praetorius Fries, Epicr. Myc. ii. 1838. Specimens 
of Venenarius Caesareus from America have been referred to this 
species. 
Amanitopsis pubescens Sacc. SyW. Fung. 5: 25. 1887. Amanita 
pubescens Schw. Schr. Nat. Ges. Leipzig i : 79. 1822. Described 
from specimens collected in grassy places in North Carolina. 
Schweinitz said it was rare, and Morgan, Beardslee, and others 
say that it has not been collected since his time. The description 
might suggest Vaginata farinosa or Vaginata agglutinata, but 
Schweinitz certainly knew the former and the volva of the latter 
could not be characterized as “vanishing.” Some forms of 
Venenarius solitariiis might be thought of, but none of them are 
quite small enough. 
Amanitopsis pulverulenta Peck, Bull. N. Y. State Mus. 116: 17. 
1907. Described from- plants collected by Peck on shaded road- 
side banks at Port Jefferson, New York, August, 1906. There 
are two boxes of specimens at Albany. One contains a single 
specimen having a long, pulverulent stipe, with bulbous base and 
no volva, and the pileus covered, except at the center, with a fine 
powder as in Lepiota cretacea. The other box contains several 
specimens, evidently the types, with short, often radicate, stems 
and caps that are sometimes gemmate. These latter plants are 
certainly Venenarius solitariiis, and there is little doubt that the 
species belongs in that category. 
Amanitopsis strangulata (Fries) P. Karst. Hattsv. i: 7. 1879. 
Agaricus strangulatus Fries, Epicr. Myc. 6. 1838. Much has 
been written about this species. Beardslee has recently studied 
it in Sweden and considers it distinct from Vaginata plumbea, 
being more robust and with an entirely different kind of volva. 
Boudier is of the same opinion. Fries’s description in the Epi- 
crisis and Battarra’s plate call for an annulus, while Fries’s later 
description and figure refer to the plant as we now know it. If
