Urocystis primulicola. Magnus. 



Spore-masses brownish black, produced in the ovary, pulverulent. 

 Spore-balls roundish or irregular, 25-50/x in diameter. Teleu- 

 tospores subglobose, ovate, or polygonal, dark brown, smooth, 

 io-i5yu, in diameter. Pseudospores much resembling the 

 teleutospores, but rather smaller and not quite so dark in 

 colour, numerous. Promycelial spores ovate or elongate, ellip- 

 tical, 10-12 X 4-5/A

ENTYLOMA. De Bary. 



Mycelium intercellular, not gelatinized. Teleutospores formed 

 within the hyphge, intercalated, never becoming pulverulent, in 

 circumscribed clusters. Promycelial spores produced on the end 

 of the promycelium. Conidia in some species produced on the 

 living host-plant from the mycelium. 



f Coniiia formed on the living host-plant. 



Entyloma fergussoni. (B. and Br.) 



Spots circular, i-3mm. in diameter, becoming whitish from the 

 development of the conidia. Teleutospores globose or irregu- 

 larly rounded. Epispore rather thin, pale brown, smooth, 

 11-13/X in diameter.
