appears as if smooth), yellow. Gills adnate, very broad behind, 2 stropkaria. 

 lines broad, somwhat crowded, dusky-umber or dusky-olivaceous, of 

 one color, quite entire. 



Stem silky-viscous when moist, when dry becoming even, shining and 

 yellowish-white, and without a manifest veil. The gills are truncate and 

 somewhat decurrent. Fries. 



Spores 17x13^ W.G.S.; elliptical, i8-2Ox8-io/x Massee. 



West Virginia, 1881-1885; Pennsylvania; New Jersey. June to No- 

 vember. Mcllvaine. 



I have enjoyed this species, which is common, since 1881. It is 

 usually conspicuous upon droppings and manure piles. It also occurs 

 on richly-manured ground, in wood and field, usually single; some- 

 times two or three are united. 



Caps and stems are edible, but do not cook in the same time. It is 

 better to cook the caps only. They are delicious.

Spores blackish-purple, I3x8/x W.G.S.; elliptical, ends rather acute, 

 !2x6/A Massee. 



Grows on dung, rich lawns and pastures. April to November. A 

 common, frequent, solitary species, easily recognized by its hemi- 

 spherical cap, dark mottled gills. At first sight it resembles Naucoria 

 semiorbicularis. 



The caps are equal to any mushroom. I have eaten it since 1881.
