On Doryalis caffra, Driefontein, Zoutpansberg Dist., 12.8.11, Doidge [1813]; Uiten- 
hage, O.P., 31.5.12, Pienaar [2420]; 17.10.06 [224]. 
Stromata epiphyllous, cellular, 3-1 mm. broad, shiny, black, subrotund to irregular, 
slightly raised, showing on the under side of the leaf as minute raised points on the dis- 
coloured leaf tissue. Leaf normally 280 u thick, hypertrophied in the region of the 
stroma, 400-500 u thick. Clypeus epidermal epiphyllous, continuous, 25-34 y thick. 
Loculi under the clypeus in the mesophyll, flask-shaped, or spherical with a wide neck, 
the base of the loculi being one-half or two-thirds of the distance through the thickness 
of the leaf; surrounded by a brown, thick wall, which is 25-38 » thick and formed 
of loosely interwoven hyphae; usually opening towards upper leaf surface, occa- 
sionally towards the lower, when it is covered by a short hypophyllous epidermal clypeus: 
occasionally two loculi on opposite sides of the leaf come into contact at their bases and 
are consequently flattened. Loculi 240-270 u diam., or 250-280 u high with a breadth 
of 200-220 u. Between the necks of neighbouring loculi a loose hyphal stroma spreads 
inwards from the clypeus. 
Asci ellipsoid, with monostichous, transverse, or partly distichous spores ; seldom 
cylindrical with distichous or imbricate monostichous spores, shortly pedicellate, foot 
usually 8-10 u long, rarely 22-30 » long; asci 80-90 u long and 12-20 u broad, according 
to the arrangement of the spores, eight-spored, paraphysate. Paraphyses numerous. 
Spores cylindrical, rounded at both ends, 26-34 u x 41-5 u, hyaline, one-celled.

On leaves of Ficus capensis, Amanzimtoti, Natal, 19.3.14, Franks [7812]; Barberton 
Dist., 16.10.13, V. d. Byl [7378]; Wyebank, Natal, 29.8.15, Doidge [9537]. 
This fungus was originally described on leaves of Ficus sp. collected at Amani, 
Usambara; the South African specimens agree with the description in all important 
particulars, but the spores are slightly narrower, the spores of the type being 7-8 p wide. 
Stromata epiphyllous, scattered or loosely arranged in groups 4—2 cm. diam., round 
or irregular, slightly raised, 1-1-5 mm. diam., dull black, not visible on upper surface, or 
showing as minute black pin-spots. Stroma originating in the lower part of the mesophyll, 
dividing the leaf into two very unequal portions, the lower narrower portion being pushed 
up by the developing stroma and forming an arch over it. Clypeus epidermal opaque, * 
25-35 ». thick. Loculi sub-spherical, less frequently flask-shaped, the narrowing in the 
latter case being due to crowding, deeply sunken in the leaf tissue, and occupying three- 
quarters or even more of the mesophyll. The base of the loculi usually rests on the 
palisade cells and the latter become filled with black, opaque stromatic tissue, which may 
or may not involve the upper epidermis. Loculi 240-400 u diam., lateral walls delicate, 
10-15 u thick, consisting of light brown, rather thin-walled prosenchyma. Asci cylindrical 
with numerous paraphyses, 90-130» = 9-11 u, straight or curved, eight-spored. Spores 
monostichous, ellipsoid, rounded at both ends, hyaline, continuous, 14—I7 u x 6-7 u.

On Peltophorum africanum, Ledzee, Zoutpansberg, 7.8.11, Doidge [1810]. 
Stromata on both surfaces of the pinnules, scattered or in groups, minute, about 
4 mm. diam., slightly convex, unilocular, smooth, shining. Loculi flattened, spherical, 
200-250 u diam., 160-180 u high, covered above and below by the epidermal clypeus, 
which only extends a short distance beyond the loculi. Lateral locular wall weak or 
wanting. Asci clavate, paraphysate, 65-80. x 14-I8u. Spores distichous, ellipsoid, 
hyaline” rounded, 13-17 ux 6-8 pu.
