 young. 



** 



Gills very hroad, more or less distant.

On the ground, near trunks in pine woods. 



Somewhat caespitose. Pileus 1^- in. across, sooty-brown, 

 at length pale and somewhat shining like the stem, which is

 Hdbk., p. 74; Cke., lUustr., pi. 1198. 



On the ground, under oaks, &c. 



Somewhat resembling C. strata, but differing in the very

 oate. 



Collybia protracta. Fr. 

 Pileus up to 1 in. across, flesh thin; convex then plare,
