Dangerous fungi somewhat resembling the M. oreades, and

GENUS COLLYBIA 



The members of this genus have white spores, and the 

 lamellae with thin edges attached to the stem by their inner ex- 

 tremity. The stem has a cartilaginous rind; that is, it is hard and 

 of a tough texture. The genus contains fifty-four American 

 species, some of which are regarded as edible, while others are 

 regarded as deleterious. The velvet-stemmed coUybia, or Col- 

 lybia vehttipas, is edible, and remarkable for its habit of growing 

 long after the frosts of winter have come. It is easily recognised 

 by its yellowish and viscid cap, and its habit of growing in tufts, 

 and developing on the stem ^ dense coat of velvety hairs. The 

 rooted collybia, Collybia radicata, may be recognised by the char- 

 acter of its stem, as the lower part is like a slender tap root, gener- 

 ally penetrating the earth to a depth equal to the length of the 

 stem above the surface,
