ATKINSON: SIX SPECIES OF AMANITA 251 
Amanita velatipes or Amanita muscaria, If Amanita velatipes is 
synonymous with Amanita jonquillea, then Amanita muscaria 
and Amanita pantherina must be thrown into the same “ melting 
ро”! 
Two more species remain to be discussed at this time, which 
have been misunderstood, and consequently united, in the two 
recent treatments of the Amanitas in this country. These are 
Amanita Frostiana and Amanita flavoconia.* 
Amanita Frostianat is a beautiful species described by Peck in 
1883. This description is brief but very accurate and illustrates 
in a striking manner not only Dr. Peck's powers of observation, 
but his critical and analytical mind. It is a rather unique pro- 
cedure, in a work of a monographic nature, in writing a diagnosis 
of Amanita Frostiana, to ignore this original description by Peck, 
and as it appears, leave out of consideration altogether any indi- 
viduals which represent this species, and deliberately draw up a 
description of Amanita Frostiana from individuals recognized as 
Amanita flavoconia, a very different species. Amanita Frostiana 
is a small to medium-sized plant. The pileus is orange or yellow, 
and distinctly striate on the margin. The volva is circumscissile 
in dehiscence. The calyptra is separated into numerous floccose 
patches on the surface of the pileus. The lower part of the volva 
is ocreate. The stem and partial veil are yellow. The spores are 
distinctly globose. 
Amanita flavoconia§ is also a small to medium-sized species. 
The colors are much as in Amanita Frostiana. But it differs from 
Frostiana in its smooth, not striate pileus, in its smaller, oboval to 
subellipsoid spores, and in its volva all friable. The lower portion 
of the volva, that which remains over the base of the stem, is 
in the form of a fine yellow powder, with not the slightest sugges- 
tion of an ocrea. The lower part of the stem broadens gradually 
to the bulb, except in rare cases when, under certain unfavorable 
environmental conditions, somewhat depauperate forms may 
result, in which the transition from the stem to the bulb is abrupt.

species.
