in the young specimens, the remnants of which remain at- 

 tached to the margin of the cap in the matured plants. The 

 whole plant has a fleshy consistency, and many species are 

 edible. The plants are found more abundantly as winter ap- 

 proaches, and the writer has collected them during November 

 after the most severe frosts. The plants grow singly or in 

 groups, but more frequently they arc thickly clustered on the 

 surface of decaying logs or stumps.

This small genus is distinguished by the absence of the 

 veil which occurs in the other genera of the brown-spored 

 group. In the young plants, the margins of the pileus are in- 

 rolled. The stem is more cartilaginous than in other genera.

The distinguishing characters of this genus are so evident 

 that the plants cannot be confounded with other genera, even 

 by the most inexperienced collector. The plants are common 

 on lawns and on decaying manure, but are sometimes found 

 on decaying stumps and logs. The caps spring up quickly 

 and disappear just as rapidly. Some of the more fragile spe-
