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^' 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. semiorMcularis, but easil)^ separated from it by its 

 more viscid pileus, paler lamellse, squamulose stem and smaller 

 spores. 



Agaricus (Hebeloma) illicitus n. sj?. 



Pileus fleshy, firm, broadly convex or expanded, smooth, hygro- 

 phanous, very dark brown when moist, a little paler when dry; 

 lamellae 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, ^-J^' long. 



Plant compact, gregarious or caespitose, 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. 



Agaricus (Hebeloma) Ascophorus n. sp. 



Pileus convex, smooth, viscid, pale alutaceous, often Avith a 

 brighter colored disk ; lamellae 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, g-^or' l<)iig- 



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 lamellae of A. spinulifer. The viscid 

 pellicle of the pileus is separable when dry. 



Agaricus (Hebeloma) excedens n. sp. 



Pileus thin, convex, gibbous or broadly umbonate, pale alutace- 

 ous inclining to russet ; lamellae rather broad, close, deeply emar- 

 ginate, terminating before the margin, minutely eroded on the
