The peridial cells, however, have side walls about twice as thick 
as in that species, and the markings are coarser and more irregu- 
lar. Inasmuch as there are a number of species of Coleosporium 
in Central America which call for the existence of Peridermiums, 
the separation of this form is made with considerable confidence.
