ENTYLOMA. De Bary. 
Mycelium intercellular, not gelatinized. Teleutospores formed 
within the hyphz, 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. 
* Conidia formed on the living host-plant. 
Entyloma fergussoni. (B. and Br.) 
Spots circular, 1-3mm. in diameter, becoming whitish from the 
development of the conidia. Teleutospores globose or irregu- 
larly rounded. Epispore rather thin, pale brown, smooth, 
11-13 in diameter.
