7 26 THE AGARICACEAE OF MICHIGAN 



solid, pruinose, smoky-luff, concolor, even. SPORES minute, 5-6 x 

 ::i micr., elliptical-ovate, smooth, white. ODOR and TASTE mild 

 or very slightly acrid. 



i Dried : Cap grayish-brown to smoky-isabelline; gills ochraceous- 



buff.) 



Suocaespitose. Ground in woods of oak, maple, etc. Ludington, 

 Ann Arbor. September. Infrequent. 



This is called the ''Clouded Clitocybe," because of the smoky hue 

 of cap and stem. The spores of the American plant seem to be 

 smaller than those of the European species, since Bresadola gives 

 them 9 x 6-7 micr. Some specimens have a bit of acridity to the 

 taste, a fact also recorded by Barla in Europe. Mcllvaine, Bres- 

 adola, Cooke, Badham, Quelet a"hd Michael report it as edible. 

 Older authors in Europe have reported it as unsafe, e. g. 

 Cordier, Paulet and Barla. The American plant has no evidence 

 against it. It is sometimes attacked by another mushroom, Vol- 

 varia loveianus, which forms fruit-bodies on its cap. (See Fig. 7, 

 PL XI, Swanson, Fungi.)
