Stilbum-form as coremia being until 2 mm. in height. As shows the 

 figure these coremia are producing conidia from their whole surface; 

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

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

 somewhat varying in length, is about 10/i.
