THE RUSTY-SPORED AGARICS 285 



Flammula carbonaria. Fr. 

 The; Viscid Flammula. 



Carbonaria is so called because it is found on charcoal or burned 

 earth. 



The pileus is quite fleshy, tawny-yellow, at first convex, then be- 

 coming plane, even, thin, viscid, margin of the cap at first inrolled, 

 flesh vellow. 



Figure 230. Flammula carbonaria. 



The gills are firmly attached to the stem, clay-colored or brown, moderately 

 close. 



The stem is stuffed or nearly hollow, slender, rigid, squamulose, pallid, 

 quite short. 



The spores are ferruginous-brown, elliptical, 7x3.5^. 



I have found this species quite frequently where an old stump had been 

 burned out. It is gregarious. I have only found it from September to No- 

 vember but the specimens in Figure 230 were sent to me in May, from Boston. 

 They were found in great abundance in Purgatory Swamp, where the grass and 

 vegetation had been burned away.
