form appeared to be that shown in the illustration. The 
plants were large, ovate when young, becoming convex and 
expanded. The colors are hygrophanous yellow or brown at 
first becoming lighter to cream color or whitish as the water 
is lost. The pileus is regular, even and smooth, covered with 
the white floccose remains of the universal veil when young, 
but soon naked. The flocci remain on the pileus under favor¬ 
able weather conditions and then the plants represent the 
variety llocculosarum. The change in color of the gills 
from white -to flesh color and then brown and the floccose 
apex of the pileus were evident in some plants but not uni¬ 
versally marked. These are the characters supposed to 
separate the species from its ally Hypholoma candolleanum. 
The apex of the stem is usually more or less striate and 
the gills never become a bright pink as in Agaricus campes- 
tris. The change is usually from whitish to a dull violaceous 
then turning purple brown with the ripe spores. The gills 
are broad and rounded at the stem narrowing toward the 
margin of the pileus, pi. XXII G. The veil is scanty and seen 
only in young plants. The further description of the species 
was given in vol. XVII, pp. 1157-1158. 
2. Form with narrow gills and irregular rugose pileus. 
PL XXII DEF. 
The illustrations show a marked form which was common 
about logs and stumps in open woods and pastures at 
Geneseo., Ills. The gills were narrow, remaining whitish for 
a long time and showing very little of the incarnate tints. 
The pilei were irregular and rugose wrinkled. The color was 
dark hygrophanous at first becoming light cream color. The 
form approaches Hypholoma leucotephrum but the stems 
were not long and slender nor markedly grooved at the apex 
as in that species. 
3. Annulate form. Stropharia irregularis Pk. PI. 
XXIII. 
In June, 1915, there was a patch of very luxuriant plants 
of this group two or three yards in extent over a buried stump 
on a lawn in Geneseo, Ills. The partial veil was very thick 
and remained as a persistent annulus on the stem, often 
becoming moveable. Otherwise they did not differ from 
Hypholoma appendiculatum which was abundant in the 
neighborhood. The veil was of the same character as that in
