Cortinarius mucosus Fr. 



Borders of woods and open places. Westport. October. This is 

 distinguished from C. c o 1 1 i n i t u s by its paler lamellae and by the even 

 surface of its stem not becoming transversely squamose. Fries regarded 

 it as a variety of C . c o 1 1 i n i t u s , but he admitted that it was almost 

 worthy of specific distinction. In our opinion it should be considered 

 distinct. 



Agaricus pusillus 7i. sp. 



Pileus fleshy but thin, fragile, convex, becoming plane, sometimes 

 slightly depressed in the center or subumbilicate, dry, silky fibrillose or 

 adorned with a few appressed fibrillose squamules, pale grayish brown, 

 often with yellowish or ferruginous stains, the center darker or brownish, 

 flesh white or whitish, not changing color where cut, taste and odor 

 amygdaline; lamellae thin, close, free, subventricose, brittle, grayish when 

 young, soon pinkish, finally brown; stem short, equal or slightly tapering 

 upward, sometimes bulbous, stuffed or hollow, slightly fibrillose, white, 

 the annulus slight, often evanescent; spores broadly elliptic or subglobose, 

 .0002 of an inch long, .00016 broad. 



Pileus. 5-2 inches broad; stem 6-12 lines long, 1-3 thick. Rich ground 

 in waste places and pastures. Delhi. S. Sherwood. October and 

 November. Specimens of this species were first received from Dr R. H. 

 Stevens, of Detroit (Mich.) They were collected on both sandy and 

 clayey soil in grassy and weedy places. From these specimens and the 

 very full notes accompanying them the description has been chiefly 

 derived. Besides specimens of the same thing, Mr Sherwood sends 

 others having a similar general appearance but a little larger, and of 

 which his notes say that the lamellae are. pale pink when young, that 

 they are wavy, and that the flavor is inferior, and wounds of the stem 

 become yellow. These may possibly be a small form of A. flave- 

 s c e n s R, b' R., but for the present we leave their identity doubtful. 



Deconica coprophila (Bu//.) Sacc 



Dung in pastures. Westport. September and October. 



Our specimens agree well with the description of this species in all 

 respects except in having the pileus viscid when moist. Fries at first 

 placed the s[>ecies in P s a t h y r a, later, in P s i 1 o c y b e, in which he 

 has been followed by most authors. In Sylloge it is placed in 

 Deconica. If that genus is recognized, it seems to be the proper 

 place for it.
