This is evently closely related to A. squarrosus, with 
which it has, perhaps, been confused, but its different colors 
and viscid pileus appear to warrant its separation. 
Agaricus (Pholiota) limonellus Pk. Pileus thin, 
convex or expanded, subumbonate, viscid, rough with scat- 
tered erect reddish-brown scales, lemon-yellow; lamell® 
narrow, close, rounded behind, whitish; stem equal, solid, 
rough with revolute or recurved scales, pallid or yellowish, 
smooth above the lacerated annulus, dusted with yellow par- 
tieles at the insertion of the lamelle; spores elliptical, 
.0003'°—.00035’ long, .0002°—.00025‘ broad. Plant czespitose, 
2'—3‘ high, pileus 1‘—2' broad, stem 2“—3“ thick. 
Prostrate beech trunks in woods. Sept. 
This is one of our most beautiful species. It is easily 
separated from its allies by its lively lemon-yellow color, 
It is allied to A. flammans. 
Agaricus (Pholiota) vermifluus Pk. Pileus convex 
or expanded, smooth, white, often tinged with yellow, some- 
times areolate-rimose, especially on de disk, the margin 
decurved, and sometimes floccose-squamose from the remains 
of the veil; lamelle close, withe, then ferruginous-brown, 
usually minutely eroded on the edge; stem hollow, striated 
at the top wehre it is sometimes thickened, white; annulus 
lacerated or evanescent; spores ferruginous-brown, .00045'— 
.0005° long, .0003° broad. Plant 2’—4' high, pileus 2’°—4 
broad, stem 3”—5* thick. 
Fields among oat stubble. Aug. 
This species is evidently closely related to A. pracox, 
but its larger size, larger spores, late appearance, ete., in- 
duce me to separate it. When moist, the pileus appears to 
be slightly viscid. It is so liable to the attacks of insect 
larvse that it is diflicult to dry a specimen before it is 
badly eaten. 
Agaricus (Inocybe) paludinellus Pk. Pileus thin, 
plane or slightly convex, umbonate, subfibrillose, whitish or 
pallid; lamelle narrow, close, whitish then subferruginose; 
stem slender, equal. colored like the pileus, with an abun- 
dant white mycelium at the base; spores subelliptical, nodu- 
lose, .0003' long, .0002° broad. Plant gregarious, 1’—2' high, 
pileus 5*—10* broad, stem nearly 1” thick. 
In low grounds and wet places under bushes. Aug. 
This species is easily recognized by its pale, umbonate 
pileus and nodulose spores. 
Agaricus (Naucoria) lenticeps Pk. Pileus thin, 
convex or nearly plane, dingy-ochre or subolivaceous, the 
disk brown or blackish-brown; lamelle plane, subdistant,
