Ampliigenous, forming black, crustaceous spots, 3-5 mm. diam. ; when 
numerous they become confluent and produce irregular, black blotches 
covering large areas of the leaf surface. Mycelium radiating, branching 
and anastomosing freely ; hyphae brown, straight, 5-6 thick, branching 
opposite or alternate ; cells 10-15 /x long ; hyphopodia alternate or opposite, 
sessile, hemispherical, flattened or shortly cylindrical, 5-8 x 5-6 fi. Thyrio- 
thecia scattered, hemispherical, opaque, 150-170 //. diam., radiating cells 
3-3 '5 [X thick, cells cubical, margin not fimbriate, but the thyriothecia are 
surrounded by a dense network of hyphae. Asci aparaphysate, 8-spored, 
broadly ovate or sub- spherical, 54-57 x 44-50 /x, much thickened round the 
apex. Spores conglobate, 2-celled, brown, slightly constricted, 33-36 x 
15-18 /X, cells equal or subequal, epispore minutely verrucose at maturity. 
Pycnidia similar to the thyrothecia but smaller, 60-120 /x diam. ; conidia 
brown with a hyaline band, oval or ovate, 15-25 x 8-14 /x.

Epiphyllous, forming round-irregular, black, crustaceous spots 3-5 /x 
diam. Hyphae brown, 6-7 /x thick, torulose, branching irregularly and 
anastomosing freely to form a network of entangled hyphae, tips of branches 
often club-shaped ; cells 14-25 /x long ; hyphopodia sessile, not very 
numerous, alternate or unilateral, hemispherical, ovate or obliquely flattened, 
6-10 X 10-6 /X. Thyriothecia gregarious, flattened-hemispherical, 300-400 /x 
diam., composed of radiating hyphae 3*5-5 /x thick, dehiscence irregular or 
stellate. Asci ovate to spherical, 8-spored, paraphysate, slightly thickened 
round the apex, 57-73 x 50-57 /x ; paraphyses numerous, filiform. Spores 
conglobate, 2-celled, fuscous, smooth, constricted, 35-40 x 13-15 /x, upper 
cell broader.
