the epidermis, causing a gall-like hypertrophy of the leaf tissues, later becoming erumpent ; 
120-160 u high, the inner part of the stroma being composed of compact brown cells 3-5 y. 
diam., prosenchymatous between the loculi, and with a darker, roughened crust. Loculi 
numerous, immersed, sub-spherical, 80-1004 diam. Asci aparaphysate, eight-spored, 
clavate or ellipsoid, thick-walled round apex, with a short foot, 45-60 u x 20-23°5 u. 
Spores hyaline, distichous, 3-septate, oblong or somewhat clavate, slightly constricted at 
the centre, 18-20u x 5-6:5u.

Ann. Myc. XIII (1915), p. 345. 
On the stem of Euphorbia schintzii, Wagenpadsnek, Pretoria Dist., 26.12.11, Pienaar 
Piso]: 31.12 AS 7353): 
Stromata only growing in the outer layers of cells and becoming apparently quite 
superficial through the rupture of the periderm, almost spherical, 14-3 mm. diam., 1}-2 mm. 
high, black, surface much wrinkled and cracked. Interior of stroma brown, the base and 
periphery being dark, opaque, formed of perpendicular, ascending hexagonal cells 15-19 u 
diam. Loculi elliptical, 250% x 9200 u, sunken under the periphery, often apparently 
free through the crumbling away of the stroma surface. Asci clavate, thick-walled, 
140-200 u x 16-32», 6-8 spored. Spores distichous or obliquely monostichous, oblong, 
four-celled, narrowed towards each end, but not pointed; straight, or one side straight 
and the other convex, verrucose at maturity. Paraphyses wanting.
