people as a delicacy, it has seemed to me worth while to 
call attention to these various forms of veil remains since 
aberrant specimens are properly open to suspicion as really 
pertaining to this species unless its variability is understood. 
It may not be amiss to say that in gathering itfor the table 
the greatest care should be taken to avoid confusing with 
it the death-cup, Amanita phalloides, which is of similar 
coloring but may be known with certainty by its larger 
ruff-like collar and the presence of a loose bag or volva at 
base of the stem. Though hardly a table collector’s char- 
acter, it may be noted further that the gills of the Amanita 
remain white as the specimens age or when heated, while 
in the smooth Lepiota they turn to a light brown as the 
plants grow stale or when they are cooked. 
Another comparable aberration is sometimes observed 
on the frequently cultivated large macaroon-flavored mush- 
room, Agaricus amygdalinus, which normally has a 
caducous large hanging ruff-like collar on the stem, but 
frequently has the veil entirely torn away from the latter, 
in which case its remnants are likely ultimately to break 
away from the pileus as well. — Plates 35, 36. 
The delicate little Hypholoma appendiculatum, which is 
frequently found in lawns, is typically characterized by 
having the veil attached to the margin of the pileus in 
irregular broken shreds (Plate 37); but in American speci- 
mens these are so frequently lacking (Plate 38) as to have 
led to its renaming in this country as H. incertum Peck. 
Here, too, the behavior of the veil is so variable as to 
call for a recognition of its several forms, among which 
is sometimes to be found a delicate broken ring hanging 
from the stem (Plate 39).
