 Cke., Illustr., pi. 150A.

C. confluens differs from the present in the densely crowded, 

 very narrow gills, and crowded habit of growth, 



Collybia confluens. Pers. 



Pileus 1 in. and more across, flesh thin but tough, flaccid ; 

 convex then expanded, obtuse, at length broadly and 

 obtusely umbonate, hygrophanous. rufescent when moist, 

 margin slightly striate ; even and altogether white when 

 dry; gills free, at length distant from the stem, very closely 

 crowded and very narrow, linear, pinkish then whitish; 

 stem 3-5 in. long, 1 line and more thick, hollow, remarkably 

 cartilaginous, apex often dilated, rufous, covered everywhere 

 with whitish down, often densely crowded and hence more 

 or less compressed ; spores subglobose, 7-9 //. diameter. 



Agaricus confluens, Pers., Syn., p. 368 ; Cke., Hdbk., p. 66 ; 

 Cke., Illustr., pi. 150 B . 



In woods, among leaves, &c. 



Growing in troops, many individuals springing from the 

 same spreading mycelium and becoming confluent, but 

 easily separating from each other, and not truly caespitose. 

 (Fries.) 



Known by the crowded habit, crowded rufous stems, 

 everywhere covered with white down, and the thin, flaccid 

 pileus. 



Densely tufted, often in large rings. Pileus 1-1 1 in.
