HYSTERINE^. 
This order includes a large number of plants which are 
intermediate between the Discomycetes and the Pyrenomy- 
cetes. By some authors they are included with the former 
and by others with the latter group. The plants of this 
group are elliptical or elongated in form, generally black 
in color and rather hard. They open at maturity with a 
long slit-like aperture, the lips sometimes spreading apart 
and sometimes remaining tightly closed. A few of the 
forms collected are included here.
