III. Spots dark brown; sori hypophyllous, prominent, 
small, but commonly in dense, wart-like clusters, dark-brown; 
spores linear-oblong, obtuse, slightly constricted, light-brown 
below, darker above, the upper cell the shorter, and with the 
epispore thickened ai the apex, 12-15 by 85-55 u; pedicels very 
short, colored. 
Spots none; soriscattered, rather large, so compact that they appear 
solid, black ; spores at length easily breaking up. The sori are scattered 
over the whole leaf, and at first lutescent, and as if sunken.—Schweinitz

The spores are light colored and fragile, when dry, much 
shrunken. Only teleutoform known. 
Schweinitz first gave the name cited above (Syn. Fung. 
Car. [1822] p. 46), and afterward (N. Am. Fungi [1834] p. 
296) changed it to P. solida. 
P. ranunculi, Seymour. 
II. Amphigenous, but mostly epiphyllous. Sori irregu- 
larly associated, often crowded but scarcely confluent, occupy- 
ing large areas or the whole of the leaf surface, little elevated, 
circular, powdery, surrounded by the upturned edges of the 
‘epidermis, ecidium-like, cinnamon-brown; teleutospores broad- 
ly elliptical, usually little or not at all constricted at the sep- 
tum, ends rounded, vertex more rarely furnished with a low,
