Report of the State Botanisi. 27 



From D. hullacea, this species differs in its not viscid pileus 

 and in its distant lamellae. The chestnut-colored specimens 

 sometimes have the center of the pileus darker than the margin. 



Deconica bulbosa w. S2?. 



Pileus submerabi'anous, convex, becoming nearly plane, glabrous, 

 slightly striate on the margin, whitish tinged with brown ; 

 lamella^ broad, distant, adnate, purplish-brown ; stem slender, 

 firm, hollow, bulbous, both it and the bulb densely grayish- 

 fibrillose ; spores purplish-brown, elliptical, .0003 in. long, .u002 

 broad. 



Pileus '.\ to 6 lines broad ; stem 8 to 12 lines long, scarcely half 

 a line thick. 



Dead stems of herbs. Delmar. September. 



This small species resembles the preceding one in size, but it 

 differs in its place of growth, its paler color, its bulbous stem and 

 in the grayish fibrils that clothe both stem and bulb. 



Coprinus arenatus w. sp. 



Pileus thin, at first broadly ovate or subhemispherical, soon 

 convex or campanulate, .adorned with small white tomentose 

 scales, striate on the margin, whitish or grayish-white, l)ecoming 

 grayish-brown with age; lamelhv broad, crowded, free, grayish- 

 white, soon purplish-brown, finall}'^ black, furnished with numer- 

 ous projecting hyaline cystidia; stem short, equal, glabrous, 

 hollow, white ; spores broadly ovate or subglobose, black in the 

 mass, purplish-brown by transmitted light, .(>(»03 to .00035 in. 

 long, .00025 to .0003 broad. 



Pileus 1 to 2 in. broad ; stem 1 to 2 in. long, 1 to 2 lines thick. 



Solitary or gregarious, growing on sandy soil recently overrun 

 by fire. Earner. May. 



The mycelium binds the sand together in a globular mass at 

 the base of the stem. The scales of the ])ileus are easil}' sepa- 

 rable and soon disappear. The marginal striations extend half 

 way or more toward the center. The long cystidia give a pecu- 

 liar appearance to the lamelhu, and in the fresh plant they may 

 be seen extending across the interspaces. The species belongs to 

 the section Tomentosi and is remarkable for its peculiar habitat.
