Report of the State Botanisi. 27 



From D. 7jul/acea, this species differs in its not viscid pileus 

 and in its distant laraelliTe. The chestnut-colored specimens 

 sometimes have the center of the pilens dai-ker than the mar<^in. 



Deconica bulbosa jl 7). 



Pileus submembranous, convex, becoming nearly plane, glabrous, 

 slightly striate on the margin, whitish tinged with brown : 

 lamelhT? broad, distant, adnate, purplish-brown ; stem slender, 

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

 fibrillose ; spores purplish-brown, elliptical. .o003 in. long, .tt002 

 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 arena tus //. s]). 



Pileus thin, at first broadly ovate or subhemispherical, soon 

 convex or campanulate, adorned with small Avhite tomentose 

 scales, striate on the margin, whitish or grayish-white, becoming 

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

 white, soon purplish-brown, finally black, furnished with numer- 

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

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

 mass, purplish-brown by transmitted light, .(»o03 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 011 sandy soil reciMitly overrun 

 by fire. Karner. May. 



The mycelium binds the sand together in a globular mass at 

 the base of the stem. The scales of the i)ileus are easily sei)a- 

 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 lamelhr, and in the fresh ]>lant they may 

 be seen extending across the interspaces. The species belongs to 

 the section Tomentosi and is remarkable for its peculiar habitat.
