Coprinus atramentarius (Bull.) Fries 

 Common Ink-cap 



Plate 3. Figure 4. X § 



Pileus 3-6 cm. broad, ovoid to campanulate, finally expanding 

 and deliquescing, glabrous or slightly scaly, especially on the 

 disk, grayish or brownish, often with a yellowish tint, blackening 

 with age; flesh white, quickly deliquescing; gills crowded, white 

 when young, soon becoming black and dissolving; spores ellip- 

 soid, black, 7-10 ix) ring sometimes apparent near the base of the 

 stem as an indistinct line ; stem slender, smooth, white, hollow, 

 5-10 cm. long. 



This species is quite common in rich soil on lawns and else- 

 where during late summer and autumn. As it appears in close 

 clusters, it may be obtained in greater abundance than the shaggy- 

 mane. Owing to its deliquescent character, it must be cooked 

 very soon after it is collected. 



Coprinus micaceus (Bull.) Fries 

 Glistening Ink-cap 



Plate 3. Figure 5. X § 



Pileus thin, ovoid to campanulate, 1.5-2.5 cm. in diameter, 

 soon expanding and becoming discolored ; surface striate, tawny- 

 yellow or tan, yellowish-orange on the umbo, usually covered 

 with minute, glistening scales when young; flesh thin, white, of 

 nutty flavor, quickly deliquescing in wet weather; gills white 

 when young, soon becoming purplish-brown and finally black; 

 spores ellipsoid, brown, 6-7 /x ; stem white, slender, fragile, hol- 

 low, 3-10 cm. long. 



The glistening ink-cap grows abundantly in dense clusters 

 about stumps and dead trunks, especially of elm, and appears 

 very early in the season, developing after rains from April to 

 November. It is of small size, but delicate in flavor and easily 

 prepared in a variety of ways. The plants should be gathered 

 young and cooked within a few hours. 



Collybia velutipes (Curt.) Fries 

 Velvet-stemmed Collybia 



Plate 3. Figure 6. X § 



Pileus 2-4 cm. broad, thin, convex to nearly plane ; surface 

 glabrous, viscid, tawny or reddish-yellow ; flesh white, not fragile,
