diam., erumpent. Conidia sy rae yellowish, uniseptate 
and slightly constricted, 10 to 14 x 5 to 6 y, one cell often 
smaller, ends rounded and obtuse, “ay curved. 
This is quite distinct from Gloeosporium Ribis (Lib.)

Acervuli large ({ to 4 mm. diam.), on small, subangular 
dark spots on faded, yellow parts of the leaf, prominent

Spots amphigenous, indefinite, 2 to 3 mm. diam., light 
dirty brown above, cinereous below. Acervuli minute (about

like punctiform, suberumpent perithecia. Sporules cylin- 
drical, subundulate, hyaline, nucleate, 20 to 30 x 24 y. 
On the same leaves are black, subangular spots, limited 
mostly by the veinlets, 2 to 4 mm. diam., the substance of 
the leaf in these spots being filled with millions of minute 
sporules (conidia)? from a size too small to be measured, 
up to 2 to 24 y, subovate, or suballantoid (Gloeosporium? 
myriosporum, BH. & E.)

slightly pruinose, subattenuated above. Head subglobose, 
4 to 4 mm. diam., pale orange. Conidia narrow-elliptical,
