 47 (with tigs.)

 nearly colorless. Conidia numerous, very variable in length, bacillary or 

 subcylindrical, colorless. Conidia numerous, very variable in length 

 bacillary or subcylindrical, colorless, 80 — 100 x 5 — 6 /^-, with 3—7 septa. 



The large spots sometimes occupy nearly half the leaf. They are 

 dry and brittle. The pure white color of the fungus contrasts beauti- 

 fully with the dark brown color of the spots. The conidia are usually 

 more abundant along the veinlets than elsewhere, and thus give a retic- 

 ulated appearance to the spots.
