On Ficus sp., Lourenco Marques, Portuguese Kast Africa, May, 1909, Howard [668]. 
Stromata only epiphyllous, on inconspicuous yellowish or brownish, discoloured spots, 
small, circular, 1 mm. diam., usually more or less regularly arranged in groups 4-1 em. 
Z 
diam., but seldom becoming confluent. Not infrequently these groups are so numerous 
that they run together, and the whole leaf surface is more or less evenly and thickly beset 
with the small stromata. Stromata convex, almost hemispherical, unilocular, between 
the cuticle and the epidermis, composed of grey brown, vertical, parallel hyphae 4-5 u 
diam. Clypeus opaque, 50-80 » thick, loculus 300-450 u diam., 150-240». high, with a 
wall 15-18 u thick composed of delicate brown hyphae and concentric in structure. Asci 
cylindrical with monostichous spores, or clavate with distichous or somewhat conglobate 
spores (in the latter case the spores are often oblique or transverse), 70-90 u x 10-16 u, | 
eight-spored. Paraphyses numerous. Spores ellipsoid, abruptly rounded at both ends, 4 
continuous, hyaline, 11-14 2 « 8-95 u.

On Ficus howardiana, Lourenco Marques, P.E.A., 30.8.1909, Howard [719]. 
Stromata epiphyllous, shiny black, small, 4-1 mm. diam., raised, irregular, between 
the cuticle and the epidermis, becoming flat at the edge. In the centre there are a few 
loculi, 120-140 » high, with opaque covering stromatal layer about 30 u thick, the inner 
part of the stroma is lighter brown. Loculi flattened-spherical or lenticular, from 220 u 
diam. and 100 u high, to 320y diam. and 115 high. Asci paraphysate, cylindrical- 
clavate, 55-65 u » 14-18, eight-spored. Spores hyaline, continuous, monodistichous, 
oval to ellipsoid, rounded at both ends, 11-13 u x 6$ u.

Jahrb. XX XIX, 1907, p. 604. 
On Ficus sp., Umgeni, near Durban, 21.3.10, Doidge [854]; Malvern, Natal, 
98.12.11, Doidge [1994]; Winkle Spruit, Natal, 29.1.12, Pole Evans [2019]; Port 
Shepstone, Natal, 15.10.12, Pole Evans [5608]; Amanzimtoti, 14.6.14, Franks [7813]. 
This fungus was originally described on Ficus hochstetteri, var. glabrior in Abyssinia. 
It appears to occur quite commonly on the Natal coast. 
Stromata epiphyllous, developed on inconspicuous yellowish coloured spots, chiefly 
along the mid-rib and lateral veins, being elongated in the direction of the vein and more 
or less confluent. Small stromata only 1 mm. long, larger ones up to 2 em. long, very 
slightly shiny, between the cuticle and the epidermis, with one or many loculi, flat, some- 
what wavy. The inner part of the stroma is prosenchymatous, composed of brown, 
parallel hyphae, perpendicular to the leaf surface, and 7-9 y thick. Loculi lenticular, 
400-600 » diam.. 250-300 vu. thick. Locular wall comparatively stout, 12-18 u thick, light 
brown, composed of numerous concentric layers of very delicate hyphae. Clypeus 40-60 u 
thick, stout, opaque. Asci cylindrical, stipitate, paraphysate, 75-110 u x 11-14 u. Spores 
usually monostichous, broadly ellipsoid, continuous, hyaline, 12-16% x 8-10. 
On the surface of young stromata a conidial layer is often developed, which produces 
hyaline, filiform, crumpled conidia.
