from Phoma samararum, on the same habitat, by its larger size 
and the faint brown halo surrounding each pycnidium; the 
latter, moreover, occurs chiefly on the wing.

Fusicoccum and Phomopsis. But there seems to exist also a pte 
with larger spores (15-16 x 3-3-5 pn), and also of an intermediate 
size (10-14 x 3-3°5 »), all otherwise very similar and represent-
