branched, the branches mostly a little swollen at the apex and bearing 
the terminal variously shaped conidia, which are obovate, oblong- 
elliptical or subglobose at first, 10-22 X 8-15 diam., and mostly 
jseptate, finally large, 25-40 x 15-25, short-clavate-oblong, 4-6- 
septate and slightly constricted at the septa, the cells divided by one 
® more longitudinal septa, dark olive-brown. The conidia are 
ener 3-6-catenulate in series, either simple or branched. As 
shown by cultures, secondary conidia often arise directly from the 
primary, thus giving rise to a secondary series. The cells of the 
eonidia at maturity incline to assume a spherical shape, and the 
eonidia then resemble somewhat asci filled with globose sporidia. 
From its habitat (inside the orange) and the character of the 
‘onidia this seems distinct from A. tenuis Nees, on orange leaves.—
