 thin, finely echinulate, 14-16 by l.'i-20 ^.

This has been named TWedo agrhmmia' ; it was placed l)y 

 Schweinitz in the Uredo section of Ca^oma, the latter including, 

 according to him, all allied species. But the s])ores are pro- 

 duced in chains, not borne singly UDon a stalk. On this ac- 

 count probably, Bonorden (Beitr. z. Kent. d. Coniomyc, p. 20) 

 assigned it to the genus Coleosporinni. hence it is known as 

 Coleonporiioii ochraceuni. Without question, however, the 

 form is not the teleuto stage. Until the latter is known it 

 must therefore be ('(t'oyiui. and the specific name should, at all 

 events, stand as above. 



C. nitens, Schw. 



Hypophyllous. Sori irregular, flat, usually thickly asso- 

 ciated and confluent, more or less covering the surface, bright 

 orange-yellow; s])ores subglobose, elliptical or oblong, epispore 

 thin, finely tuberculate, 12-24 by 18-32 ^; spermagonia scat- 

 tered, numerous, yellow, mostly on upper side of leaf.
