34 Thirty-first Report on the State Museum. 



behind, whitish ; stem equal, solid, rough with revolute or recurved scales, 

 pallid or yellowish, smooth above the lacerated annulus, dusted with yellow 

 particles at the insertion of the lamellae ; spores elliptical, .0003 -.00035' 

 long, .0002'-.00025' broad. 



Plant caespitose, 2 '-3' high, pileus l'-2' broad, stem 2"-3'' thick. 



Prostrate beech trunks in woods. Griffins. 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. flamrnans. 



Agaricus (Pholiota) vermifluus Pk. 



Pileus convex or expanded, smooth, white, often tinged with yellow, some- 

 times areolate-rimose, especially on the disk, the margin decurved, and some- 

 times floccose-squamose from the remains of the veil ; lamellae close, white, 

 then ferruginous-brown, usually minutely eroded on the edge ; stem hollow, 

 striated at the top where 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. Ticonderoga. Aug. 



This species is evidently closely related to A. prcecox, but its larger size, 

 larger spores, late appearance, etc., induce me to separate it. When moist, 

 the pileus appears to be slightly viscid. It is so liable to the attacks of insect 

 larvae that it is difficult to dry a specimen before it is badly eaten. • 



Agaricus (Inocybe) paludinellus Pk. 



Pileus thin, plane or slightly convex, umbonate, subfibrillose, whitish or 

 pallid ; lamellae narrow, close, whitish then subferruginose ; stem slender, 

 equal, colored like the pileus, with an abundant white mycelium at the base ; 

 spores subelliptical, nodulose, .0003' long, .0002' broad. 



Plant gregarious, l / -2 / high, pileus 5"-10" broad, stem nearly 1" thick. 



In low grounds and wet places under bushes. Sandlake. Aug. 

 This species is easily recognized by its pale, umbonate pileus and nodulose 

 spores. 



Agaricus (Naucoria) lenticeps PJc. 



Pileus thin, convex or nearly plane, dingy-ochre or subolivaceous, the disk 

 brown or blackish-brown ; lamellae plane, subdistant, adnate, with a decurrent 

 tooth, whitish or pallid ; stem slender, hollow, paler above and slightly squa- 

 mulose ; spores large, variable in size, .0005'-.00075' long, .0003 -.0004' 

 broad. 



Plant P-1.5 high, pileus 6 '-10 ' broad, stem scarcely 1" thick. 



Sandy soil along railroads. Center. Oct. 



Agaricus (Hypholoma) hymenocephalus Pk. 



Pileus thin, fragile, campanulate then expanded, sometimes umbonate, 



i hygrophanous, brown and striatulate when moist, pallid or whitish and radi- 

 ately rugulose when dry, subatomate, the whitish appendiculate veil soon 

 evanescent ; lamellae narrow, close, dingy then brown ; stem slender, brittle,
