Associated with Meliola Cryptocaryae, on leaves of Cryptocarya Woodii^ 
MajviUe, Natal, 22/7/15, Wood, 9025. 
On Cryptocarya Woodii, Berea, Durban, 29/1/17, v. d. Bijl, 11362. 
3. Asterinella Burchelliae Doidge, sp. nov. 
Plate XYII, fig. 37. Slides lY, 20 ; XXXIV, 9 ; XL, 4. 
Epiphyllous, forming minute, black spots about 1 mm. diam. Myce- 
lium poorly developed ; hyphae brown, 3*5-5 thick, frequently septate, 
undulating, somewhat torulose, cells 10-13 /x long. Thyriothecia 100-120 /x 
diam., brown, flattened hemispherical, formed of radiating hyphae about 
3 fx thick, margin somewhat fimbriate. Asci ellipsoid to cylindrical, thickly 
tunicated round the apex, sessile, aparaphysate, 27-37 X 16-20//. Spores 
13-17 X 5-6*5 /X, oblong to clavate, rounded at both ends, upper cell 
shorter. 
On leaves of Burchellia capensis, Woodville Forest, G-eorge, 11/11/17, 
Doidge, 10940. 
Closely related to Aster ina gibhosa, from which it differs in the poorly 
developed mycelium and in the absence of regular nodular swellings. 
4. Asterinella lembosioides Doidge, sp. nov. 
Plate XYII, fig. 39. SHdes XLIII, 4-6. 
Mycelium slender, arachnoid ; hyphae fuscous, 1*5-3 /x thick, tortuous 
frequently branched and anastomosing. Thyriothecia scattered, hemi- 
spherical, 200-240 /X diam., or broadly ellipsoid, 280-320 x 160-240 /x ; 
formed of radiating hyphae about 2 /x thick, dehiscing by an irregular 
central fissure. Asci very numerous, paraphysate, ellipsoid to cylindrical, 
33-43 X 17-20/x, somewhat thickened round the apex, which is traversed by 
a terminal pore ; paraphyses numerous, hyaline, exceeding the asci, filiform, 
swollen, club-shaped at the tips. Spores conglobate or sub-distichous, 
15-17 X 8*5-10 /X, 2-celled, fuscous, scarcely constricted cells sub-equal. 
Pycnidia similar to the thyriothecia ; conidia hyaline, continuous, lunate, 
17-18 X 1*5-2 /X. 
Parasitic on the mycelium of Balladyna velutina and Meliola amphi- 
tricha, on leaves of Plectronia Guieiizii, Buccleuch, Natal, 17/7/11, Doidge, 
11574. 
Lbmbosia Lev. 
Syll. Fung, ii, p. 741 ; Theissen, Lembosia-studien, Ann. Myc. xi 
(1913). 
Mycelium superficial, hyphae branched, septate, with liypliopodia. 
Thyriothecia dimidiate, inverse, formed of radiating hyphae, typically 
oblong-linear, dehiscing by an irregular longitudinnl fissure. Asci apara- 
physate, 8-spored. Spores 2-celled, brown.
