a plant is seen growing apart from the general mass and then its

 glabrous, pale ochraceous, flesh white, taste farinaceous ; lamellae 

 broad, subdistant, rounded behind or emarginate, whitish ; stem 

 lirm, slender, glabrous, stuffed or hollow, colored like the pileus ;

Woods. Shokan. September. Kelated to C. esculenta, but 

 distinct by its umbilicate or depressed pileus and its farinaceous 

 odor and taste.

Mycena rugosa Fr. 

 Woods. Shokan. September. 



Entolonia nidorosum Fr. 

 Woods. Shokan. September. 



Our specimens differ from the type in having the stem solid 

 and the lamella? adnate. For the present I designate them as 



Yar. solidipes. 



Tubaria canescens n. sjy. 



Pileus very thin, almost membranous, convex, gra3ish-white or 

 canescent, coated with minute whitish fibrils or appressed tomen-
