68 TWENTY-FOURTH REPORT ON THE STATE MUSEUM. 
sometimes with a slight decurrent tooth, at length pale cinnamon 
color; stem equal, hollow, minutely floccose-scaly, yellowish ; 
spores 3,45, long. 
Plant gregarious, 1’-1.5' high, pileus 6’-12" broad, stem 1” thick. _ 
Burnt ground. Top of one of the “ Highlands,” near Highland 
Falls. June. 
Allied to A. semiorbicularis, but easily separated from it by its 
more viscid pileus, paler lamellz, squamulose stem and smaller 
spores. 
Agaricus (HEBELOMA) ILLICITUS 2. Sp. 
Pileus fleshy, firm, broadly convex or expanded, smooth, hygro- 
phanous, very dark brown when moist, a little paler when dry; 
lamelle close, broad, tapering outwardly, plane or ventricose, 
rounded behind with a very slight decurrent tooth, pale dingy 
brown ; stem firm, equal, hollow, scabrous, distinctly striate at the 
top, paler than the pileus, with a white mycelium; spores sub- 
elliptical, z5,7 long. 
Plant compact, gregarious or ceespitose, 1.5—2' high, pileus 
1'-1.5' broad, stem 2" thick. Rotten sticks and logs In woods. 
Greig. September. (Plate 4, Figs. 1-5.) The habitat is unusual 
for species of this subgenus. 
Acaricus (HEBELoMA) ASCOPHORUS 7. Sp. : 
Pileus convex, smooth, viscid, pale alutaceous, often with a 
brighter colored disk ;. lamellze moderately broad, close, emarginate, 
attached, pallid or subolivaceous, stem equal, short, stuffed or hol- 
low, slightly fibrillose, paler than the pileus; spores produced in 
fragile, globose asci borne on a thick, tapering, penetrating pedun-

cle, elliptical, 5,5, long. 
Plant 1’ high, pileus 6’-12” broad, stem scarcely 1" thick. Burnt 
ground in pastures. Greig. September. (Plate 3, Figs. 1-6.) 
A species remarkable for the peculiar manner in which the 
spores are produced. There are a dozen or more in each ascus. 
Under slight pressure on the slide of the microscope the envelop- 
ing membrane bursts and separates from its peduncle which is of a 
firmer structure and bears some resemblance in size, shape and 
color to the spinules on the lamellz of A. spinulifer. The viscid 
pellicle of the pileus is separable when dry. 
Agaricus (HEBELOMA) EXCEDENS 2. Sp. 
Pileus thin, convex, gibbous or broadly umbonate, pale alutace- 
ous inclining to russet; lamella rather broad, close, deeply emar- 
ginate, terminating before the margin, minutely eroded on the
