Stilbum-Ï'ovm as coremia being until 2 mm. in licight. As shows the 

 figure these coremia are producing conidia from tiieir whole surface; 

 the conidia are cylindric-clavate or obpyriform, 2 — 3 septated, 50— 60/^ 

 X 18 — 20^, and the average breadth of the conidiophores, which are 

 somewhat varying in length, is about IO/7.
