This has been named UrnJo aijriinoitiir; it was ])laced by 

 Schweinitz in the Ureclo section of Ca'oma^ the latter including, 

 according to him, all allied species. But the spores are pro- 

 duced in chains, not borne singly uv)on a stalk. On this ac- 

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

 assigned it to the genus Coleosporiiim. lience it is known as 

 Coleospoi-iiftn ochrarevm. Without (jucstion. liowever. the 

 form is not the teleuto stage, lentil the latter is known it 

 must therefore be (^a'onia, and the s|)eciHc 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: spores subglobose, elliptical or oblong. e]nspore 

 thin, finely tubercnlate, 12-24 by 18-32 m; spermagonia scat- 

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