Growing on the ground about old stumps. New England, Frost ; 

 New York, Schweinitz ; N. Carolina, Curtis \ S. Carolina, Favenel; 

 Alabama, Peters. Plant 67 inches high, stipe about ^ of an inch 

 thick in the middle, pileus i inch in height. This plant though so 

 frequently met with does not appear to have been described again 

 since the time of Bosc ; it is desirable that some one finding it should 

 make a careful study of it and give a fuller description. 



Genus II. Mutinus, Fr. 

 Stipe hollow within, the wall composed of a single layer of round- 

 •celled tissue; pileus wholly adnate to the summit of the stipe, the 

 gleba occupying its outer surface.

 Morgan. Plant 4-7 inches in height, the stipe ^ of an inch in 

 thickness, the volva not much thicker and i-ij/2 inches in height;
