 changed and roughened seed coat, 1-3 mm. in diameter, the re- 

 mainder of the inflorescence unchanged ; spores regularly oval, 

 distinctly echinulate, about 7-9 fx in length.

 distinguished from them by its larger pustules and smaller spores. 

 It has nothing in common with U. Dactyloctaenii P. Henn. Die
