ENUMERATION AND DESCRIPTION OF THE 
SEPTORIAS OF NORTH AMERICA. 
BY GEORGE MARTIX, M. D . 
This genus was described by Fries, S. M., Vol. 3, p. 480. Its char¬ 
acter, as now accepted, is as follows : Perithecia globose or lenticular,’ 
thinly membranaceous, pierced with a small opening or fissured, usually 
developed beneath the epidermis in discolored spots on leaves, through 
which they generally burst or become erumpent; sporules cylindrical, 
linear or filiform, pluriseptate or guttulate, rarely entire, hyaline, often 
discharged in gelatinous threads or masses ; basidia small or none.
