It varies with a smootli and nearly solid stem, or subsquamose, Trith a 

 central pith. A vertical section sliows a groove round the top of the stem, 

 and a cavity towards the top of the peridium, in consequence of the flocci 

 being shorter above. Spores bright ferruginous. — M.J.B. (Fig. 112.)

GEASTER, Mich. 



Peridium double, outer 

 distinct, persistent, burst- 

 ing, and dividing into several 

 stellite lobes. — Fr. S.3I.in.

 (Fig. 113.; 



In one species the inner per- 

 idium is supported by several 

 stems, and the orifices are numer- 

 ous. This has led to its removal 

 by some mycologists from this 

 to a new genus. We prefer to retain it as a sub genus. In the rest the 

 orifice and support is single. None of the species are common.
