in. Spots dark brown; sori hypophjllous, 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 at the apex. 12-15 by 35-55 ^u.; pedicels very 

 short, colored. 



Spots none ; sori scattered, 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

III. 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, aecidium-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,
