The compressed peridium affords a ready means of distin- 
guishing between this genus and Tulostoma , its nearest relation.

The whole plant is at first enclosed in a volva as in Phallus , 
which is buried several inches deep in loose sand, and after the 
almost complete differentiation of the gleba, the peridium is 
elevated into the air by the sudden increase in length of the 
stem, which sometimes measures fourteen inches in length. 
When the plant is carelessly drawn up by the stem, the volva 
is left behind.
