Agaricaceee 



Cortinarms. obtuse, regular, slightly viscid, even, smooth, the thin margin at first 

 incurved, appendiculate with the cortina. Flesh firm, white. Stem 

 curt, i% 2% in. long, i in. and more thick, bulbous, absolutely im- 

 marginate, compact, shining white, adpressedly flocculose, the superior 

 veil pendulous. Gills emarginate, thin, somewhat crowded, at first 

 narrow, violaceous-purplish) then broader and ochraceous-cinnamon, 

 always quite entire. 



Variable in stature, but the habit and colors are always unchangeable. 

 It varies with the stem taller and somewhat equal, the pileus yellow- 

 tawny, and the gills dark blue. Fries. 



In woods. Uncommon. September to November. Stevenson. 



Minnesota; Ohio. 



Edible. Cooke, 1891.

Mushroom beds, manured soil in conservatories or in plant pots.

This interesting species is closely allied to Cortinarius multiformis and 

 belongs to the Section Phlegmacium. It has a slight odor of radishes 

 and is pronounced edible by Mr. Mcllvaine. Its habitat is peculiar, 

 but it possibly finds its way into conservatories and mushroom beds 

 through the introduction of manure or soil, or leaf mold from the woods. 

 It seems strange, however, that it has not yet been detected growing in 

 the woods or fields. Hebeloma fastibile is said sometimes to invade 

 mushroom beds, and our plant resembles it in so many particulars that 

 it is with some hesitation I separate it. The chief differences are in 

 the stem and spores. The former, in Hebeloma fastibile, is described
