106 Forty-sixth Report on the State Museum. 



Mr. Falconer says that under cultivation it is exceedingly pro- 

 ductive, growing equally well in sunshine and in shade, but being 

 fond of warmth. When grown in the dark the color of the 

 pileus is darker than Avhen grown in the light. The mushrooms 

 appear in twenty-four to thirty days after the planting of the 

 spawn, which is about two weeks earlier than in the case of the 

 common mushroom. They have a decided flavor and are good 

 eating. From this it will readily be seen that in productiveness, 

 early appearance and abilit}^ to endure warm weather it is an 

 improvement on the common mushroom. 



Hypholma aggregatum n. sp. 



Densely Ccespitose ; pileus thin, convex or subcampanulate, gray- 

 ish-white, obscurely spotted with appressed brownish fibrils; 

 lamellse subdistant, rounded behind, nearly free, at first whitish, 

 then brown or blackish-brown with a whitish edge ; stem rather 

 lono", hollow, somewhat iioccose or fibrillose, white ; spores brown, 

 elliptical, .0003 in. long, .00016 to .0002 broad. 



Pileus about 1 in. broad ; stem 2 to 3 in. long, 1.5 to 2 lines 



thick. 



At the base of trees and stumps in woods. Alcove. Sept. 



The ca3spitose habit and obscurely spotted grayish-white pileus 

 are marked features of this species. From B. silvestre the species 

 may be distinguished by its smaller size, adnexed or nearly free 

 lamellse, which have no rosy tint, and by its very casspitose mode 

 of growth. 



Deconica bry opMla n. sjj . 



Pileus thin, membranous on the margin, subcorneal, becoming 

 convex or nearly plane, glabrous, hygrophanous, chestnut color 

 or dark brown and striatulate on the margin when moist, creamy- 

 white, grayish-white or pale brown when dry and often distmctly 

 striate on the margin ; lamellae broad, distant, adnate or slightly 

 decurrent, plane or ventricose, at first pale-brown, then purplish- 

 brown ; stem slender, slightly silky-fibrillose when young, stuffed 

 or hollow, pallid or brown ; spores brown, elliptical, .0003 in. 

 long, .0002 broad. 



Pileus 3 to 6 lines broad ; stem 8 to 12 lines long. 



Sandy soil among mosses. Delmar and Karner. May.
