Fromme: A New Gymnosporangial Connection 229 
still incomplete. I am therefore appending a description of the 
pycnia and aecia with the complete synonomy of the combined 
species and its distribution. The first name applied to the telial 
stage was Podisoma Ellisii Berk., in 1874; which was, however, 
antedated by the Schweinitzian name.

0. Pycnia epiphyllous, gregarious, in crowded circular groups. 
2-5 mm. in diameter, on blackened areas, subepidermal, orange- 
yellow, globose in vertical section, 140-190 /x broad by 175 /x deep ; 
ostiolar filaments 30-80 /x long.

groups, on discolored hypertrophied areas, cupulate, 0.2-0. 3 mm. in 
diameter ; peridium yellowish, fragile, becoming lacerate to the 
base, slightly recurved ; peridial cells oblong, 26-29 by 32-39 /x, 
overlapping, the outer wall thick, y-JO/i, smooth, transversely 
striate, the inner wall much thinner, 2-3 /x, closely and prominently 
verrucose; aeciospores globoid to oblong, 24-30 by 27-34^, the
