232—THE TYLOSTOMEAE. 
This tribe is distinguished by having a long stipe which is 
distinct from the peridium The only other tribe of truly stalked 
puff-balls (Podaxineae), has the stipe continuous to the apex of the 
peridium, forming an axis. We have representatives of five genera. 
KEY TO THE GENERA. 
Peridium opening by circumscissile dehiscnce.Battarrea. 
Peridium not dehiscing circumscissile. 
Stipe inserted in a “ socket’’ in base of peridium. 
Small plants, mouth apical.Tylostoma. 
I v arge plants dehiscing irregularly . . .... Oueletia. 
Peridium seated on the broad apex of the stipe. 
Peridium opening by an apical mouth.Chlamydopus. 
Peridium opening irregularly.Dictyoceplialos. 
2 3 3—BATTARREA. 
A curious genus with a long stipe, and a peridium that dehisces 
circularly, the top part coming off like a lid. We have two spe- 
. cies in our collection from the Western States, but are not sure about 
them, and therefore will not publish the species until we can further 
satisfy ourselves.

This genus is represented by a num¬ 
ber of species in this country, and I have 
thus far been able to do very little with 
them by means of the literature on the 
subject. They are all little stalked 
plants, as shown in figure 67. The peri¬ 
dium has at the base a kind of ‘ ‘ socket 
into which the stipe is inserted. We 
expect at some future day to present a 
paper by which our species may be 
recognized. It is impossible to do it 
now.
