Mycologia 



i. Agaricus comtulus Fries, Epicr. Myc. 215. 1838 



Pileus subfleshy, campanulate to plane, 2-3 cm. broad; surface 

 dry, appressed-silky or glabrous, white with a yellowish or rosy 

 tint, becoming yellow on drying or when bruised, often darker at 

 the center and with age; context thin, white, tinged with yellow, 

 with mild taste and no characteristic odor ; lamellae free, crowded, 

 broad in front, pale-pink to purplish-brown; spores broadly ellip- 

 soid, almost subglobose, very rounded at the ends, pale-purplish- 

 brown under the microscope, about 4.5 x 3.5 stipe tapering up- 

 ward, hollow, whitish, luteous at the base, becoming yellow on dry- 

 ing or when bruised, 3-6 cm. long, about 4 mm. thick; annulus 

 delicate, yellowish-white, often fugacious. 



Type locality: Europe. 



Habitat : On the ground in open woods or in rich, grassy places. 

 Distribution : New England to Alabama and west to Michigan ; 

 also in Europe.

Specimens so named at Albany from Delmar and Menands seem 

 to agree perfectly with material from Bresadola. Kaufifman finds 

 it rare in Michigan and says it needs more study. I have studied 

 fresh specimens found here in the hemlock grove and Miss Eaton 

 has drawn them in color. 



2. Agaricus alabamensis sp. nov. 



Pileus convex, cespitose, 3-5 cm. broad ; surface smooth, of com- 

 pacted fibrils, white, yellowish on drying, entire on the margin, the 

 pellicle exceeding the lamellae by 2 mm. ; context dry and spongy, 

 white, with a distinctly sweetish taste and no odor ; lamellae free, 

 densely crowded, rather straight and narrow, cream-white to pink, 

 then changing to brown ; spores broadly ellipsoid, rounded at the 

 ends, occasionally obliquely apiculate at the base, dark-purplish- 

 brown under the microscope, 5.5-6.5 x 4-5 /x; stipe slightly taper- 

 ing upward, solid, smooth, of compacted fibrils, white, yellowish on 

 drying, 6-8 cm. long, 1 cm. thick ; veil thick, white ; annulus heavy, 

 distant about 1.5 cm. from the pileus. 



Type locality : Auburn, Alabama. 

 Habitat: In clay soil in a plowed field. 

 Distribution : Known only from the type locality.
