REEORT OF THE STATE BOTANIST. 155 
AGARICUS CRISTATUS, A. & S. 
Crested Agaric. 
Pileus thin, campanulate or convex, then nearly plane, odtwse, at 
first with an even reddish or reddish-brown surface, then white adorned 
with reddish or reddish-brown scales formed by the breaking up of the 
cuticle, the central part or disk colored like the scales ; lamellze close, 
free, white; stem slender, hollow, equal, smooth or silky-fibrillose be- 
low the ring, whitish, annulus small, white ; spores oblong or nar- 
rowly subelliptical. .0002' — .00028' long, .00012' —.00015' broad. 
Plant 1’—2' high; pileus .5'—i.5' broad ; stem 1” — 2” thick. 
Grassy places and borders of woods. June — September. 
This species is easily known by its small size and the crested ap- 
pearance of the white pileus, an appearance produced by the orbicular 
unruptured portion of the cuticle that remains like a colored spot on the 
disk. The fragments or scales are more close near this central part and 
more distant from each other toward the margin, where they are often 
wholly wanting. The scales are sometimes very small and almost 
granular. In very wet weather the margin of the pileus in this and 
some other species becomes upturned or reflexed. 
The spores when viewed in one position appear as if truncated at 
one-end and acute or pointed at the other, in another position they 
appear narrowly elliptical, the truncate end being slightly rounded. 
The spores of A. Friesii are somewhat similar in shape but are a little 
longer. 
The plant usually has a distinct odor. 
AGARICUS RUBROTINCTUS, Pk. n. sp. 
Red-tinted Agaric. 
Pileus thin, convex or nearly plane, sometimes slightly and broadly 
umbonate, at first even with a reddish or pinkish surface, a little 
darker and sometimes slightly rough on the disk, then adorned with 
appressed scales formed by the breaking up of the cuticle ; lamelle 
close, free, white or whitish ; stem hollow, equal or slightly thickened 
at the base, smooth or slightly silky-fibrillose below the annulus, 
whitish, the annulus well developed, membranous, white or pinkish, 
persistent ; spores subelliptical, wninucleate, .00035' — ,00045' long, 
.0002' — .00025’ broad. 
Plant 1.5’ — 3.5’ high; pileus 1’— 2.5’ broad; stem 2” — 3” thick. 
Thin woods and open places. July—September. Helderberg 
mountains and Hast Worcester.
