45. Phyllachora Lessertiae n. sp. 
On leaves of Lessertia tenuifolia, Smits Kraal, Boshof Dist., June, 1911, Burtt-Davy 
[1568]. 
Stromata amphigenous and petiolar, but mostly epiphyllous, scattered or crowded, 
minute, up to 0-5 mm. diam., somewhat raised, dull black, mostly unilocular. Stroma 
reduced to a clypeus above each loculus, 100-120 u broad, and certain hyphal strands 
and knots under the clypeus and extending beyond it in the sub-epidermal cells. Loculi 
sub-spherical to pyriform, 169-190 u diam., 200-240 u high, occupying about one-third 
of thickness of leaf. Locular wall about 15 u thick, consisting of delicate, compressed, 
colourless hyphae, broader near apex and darker coloured, fusing above with clypeus. 
Asci eight-spored, paraphysate, cylindrical or narrow-ellipsoid, with a very short foot, 
80-90 vu. x 12-16 -5 u. Periphyses present. Spores one-celled, hyaline, ellipsoid, rather 
thick-walled, obliquely monostichous or sub-distichous, 15-17 u x 8-5-10 u. 
Phyllachora Lessertiae Doidge, nov. sp. 
Stromata plerumque epiphylla, sparsa, minuta, usque -5 mm. diam., vix vel leniter 
convexa, atra, clypeo epidermale, 100-120 vu lato, unilocularia. Loculi subglobosi v. pyri- 
formi, 160-190 vy. diam., 200-240 u. alti, parietibus circ. 15 py crassis. Asci octospori, para- 
physati, cylindracei, v. ellipsoidei, brevissime pedicellati, 80-90 u x 12-16-5y. Sporae 
continuae, hyalinae, ellipsoideae, utrinque rotundatae, 15-17 u x 8-5-10 u. 
46. Phyllachorella rikatliensis n. sp. 
On leaves of Andradia arborea, Rikath, P.E.A., September, 1918, Junod [11736]. 
Stromata minute, punctiform, about 0-3-0-5mm. diam., amphigenous, penetrating 
right through the leaf, scattered over greater part of leaf surface or in round irregular 
patches about 5 mm. diam., black shining, slightly convex. Epidermal clypeus on both 
sides of leaf, black, opaque, about 20 u thick, only extending a small distance on each 
side of the loculi. Inner part of stroma of usual prosenchymatous structure; in this the 
loculi are embedded. Stroma may contain a single flattened spherical loculus, 240-250 u 
diam., 140-150 » high, or a single pyenidium of similar dimensions. Very frequently the 
flattened spherical loculus is about 300 1 diam. and has a small lenticular pycnidium cut 
off from one surface; exceptionally, there are two smaller loculi and a pyenidium, the shape 
of each being an irregular cone on a curved base. Locular wall about 10 vu thick. 
Asci aparaphysate, clavate, eight-spored, 50-60%. ™* 13-15 u. Spores usually 
distichous, crowded in ueper half of ascus, hyaline, one-celled, oblong, rounded at both 
"ends, 10-13-5u x 3:5-5u. 
Conidia brown, oblong, continuous, 13 -5-15 u * 6-7 p. 
Phyllachorella rikatliensis Doidge, nov. sp. 
Stromata amphigena, minuta, circ. 0:3-0) -5 mm. diam., atra, nitidula. leniter convexa. 
Loculi 1-3 in quoque stromate, sub-globosi v. compressi, 240-300 vu. diam., 140-150 u alti, 
clypeo atro, opaco, 20 u crasso, parietibus 10 y crassis. Asci aparaphysati, clavati, octo- 
spori, 50-60 2 x 13-15 u. Sporae plerumque distichae, hyalinae, continuae, oblongae, 
utringue rotundatae, 10-13-54. « 3-5-5 yu. Pycnidia loculis ascogenis similes, conidiis 
brunneis, oblongis, continuis 13-5-15 4 x 6-7 u. 
Hab. in foliis Andradiae arboreae, Rikatli, P.E.A., 1918, leg. Junod [11726].

Natal, 3.7.13, Pole Evans [6809]. 
Stromata epiphyllous, minute, punctiform about 0-3 mm. diam. or becoming larger 
by confluence, somewhat convex, black shiny, showing on the under-surface only as minute, 
brown blisters, uni- or bilocular. Clypeus epidermal, dark brown, sub-opague, ca. 15 u 
thick, spreading to a diameter of about 500 u. Loculi sub-spherical to lenticular, 240-320 u
