been referred to that genus, but mycologists generally place it in 

 the genus Tricholoina. The spores, when dropped on white paper, 

 have not tlie clear white color shown by those of most species of 

 Tricholoma. The color is dingy-white or sordid-white. 



Clitocybe Fr. 

 The genus Clitocyhe differs from Tricholoma in the character 

 of the gills. They are attached to the stem by their inner 

 extremity as in that genus, but they are not notched or excavated 

 on the edge near the stem, and they are generally decurrent. 

 Several of our species have been recorded as edible, but trial has 

 been made by us of only a few of them. Those here described 

 are tabulated below. 



Cap thick- fleshed, witli no reddish hues 1 



Cap thin-fleshed, more or less reddish 2 



1 Cap grayish, gills close together C. nebularis. 



1 Cap brown or blackish-brown, gills wide apart. C. media. 



2 Cap funnel shaped when mature C. infundibuliformis. 



2 Cap convex or nearly plane when mature ... C. laccata. 



Clitocybe nebularis Batuch. 

 Clouded Clitocybe. 



Plate S3. Figs. 8 to 13. 



Pileus Heshy, firm, at lirst convex, becoming nearly flat; 

 lamelte crowded, adnate or slightly decurrent, white or slightly 

 tinged with yellow; stem firm, fibrillose, generally thickened at 

 the base; spores elliptical, white, .ono2 in. long. 



The Clouded clitocybe is a rather large and firm mushroom 

 with the cap at first convex, but when mature it becomes nearly 

 flat or a little depressed. It is smooth and of a grayish or 

 clouded-gray color, often becoming paler with age and sometimes 

 evidently with a slight yellowish tint. The center of the cap is 

 sometimes darker than the margin. In the American plant the 

 color is generally paler than that of the European plant, as indi- 

 cated by the |)ublished figures. The color of the flesh is white. 



The gills are quite closely placed, and in the young plant are 

 attached to the stem by the whole width of the inner extremity, 

 but as the cap expands they appear to run down upon the stem 

 and terminate in a narrow point. They are white or slightly 

 tinged with yellow.
