Stromata visible on both sides of the leaf, scattered or in rows, on yellowish leaf spots, 
ellipsoid, 4-1 «x 4-4 mm., dull black ; clypeus in both upper and lower epidermis, 20 u 
thick, opaque. Locul few, ellipsoid, 100-150 u high, 260-230 u diameter, with thinner, 
delicate, brown lateral walls. Asci cylindrical, club-shaped, 70-120 x 8-12 »; paraphysis 
numerous. Spores mono- or distichous, ellipsoid to oblong, rounded at both ends, straight, 
colourless, 14-18 x 6-8 vu. Conidia filiform or sickle-shaped, 15°25 x 1 wu.

On leaves, Inanda, Natal, 1881, Medley Wood (Wood No. 581) [9487 and 10443]. 
Stromata unilocular, punctiform, only visible on the upper leaf surface, convex, black, 
shining, thickly crowded on yellow leaf spots, 6-10 mm. in diameter. Loculi flattened 
spherical, 220— 260 u diameter, 130-160 u high; the base does not reach as far as the lower 
epidermis : the loc ular wall is 8-10 u thick, consisting of brown cells, but weakly developed, 
and here and there not very distinct : at the apex it unites with the short black epidermal 
clypeus. Asci cylindrical, paraphysate, eight-spored, briefly pedicellate, 60-70 x 8-12 u. 
Spores distichous or obliquely monostichous, oblong, colourless, one-celled, straight, with 
blunt ends, 13-15 x 43-53 u.

Stromata oonspie uous on both leaf surfaces, scattered or crowded and arranged in rows, 
round or oblong, }—l mm. long, or forming larger stromata by confluence, black, opaque, 
plurlocular. Loe vali irregular, large, 280-400 u long, 200-300 u high. Clypeus in both upper 
and lower epidermis, 15-25 g thick, lateral wall of loculus 8—LO » broad, brown: stylospores 
straight or flexuous, continuous, filiform, hyaline, 18-35 x 1 u. Asci clavate, rounded 
at the apex, 70-95 » 20-26 u, elsht-spored, paraphysate ; spores dishes or obliquely 
monostichous, broadly row nded at both ends, continuous, hyaline, 17-24 x 11-18 u.

Both leaf surfaces are comparatively thickly beset with stromata, which are round 
or elliptic, }-1 mm. diameter, convex, somewhat shiny, not usually coalescing, and not 
situated on discoloured leaf areas, the whole leaf becomes yellow. Clypeus epidermal, 
20 u thick, on one or both leaf surfaces. Loculi about 4-10 in each stroma; when the 
stroma Is only on one side of the leaf, occupying about two-thirds of its thickness, closely 
crowded, 180-230 u diameter, 160 » high. When two stromata occur at the same point 
on opposite sides of the leaf the loculi only reach the centre. Wall brown, about 10 u thick. 
Asci cylindrical, paraphysate, 60-80 x 10-16 u, eight-spored ; spores mostly distichous, 
ellipsoid, tapering somewhat to both ad. but rounded, one-celled, hyaline, 13-17 X 7-8 u.

On leaves of Teclea natalensis, 5.6.15, Kentani, Pegler (Pegler No. 2324) [9079]. 
Stromata in small groups on yellow leaf spots, developing on both sides of the leaf, 
with a preference for the upper surface, visible on both leaf surfaces, oval, ellipsoid or 
almost round, 0°5 to 2°5 mm. long, black, somewhat shiny, raised on both surfaces, but not
