mosing. Capitate hyphopodia alternate, distant, stipitate, 2l'5-29 /x long; 
upper cell irregular, more or less lobed, 14-5-18 x 14'4 mucronate 
hyphopodia not very numerous, paler, opposite, ampulliform, rather slender, 
suddenly narrowed near the apex into a short neck, measuring about 
7 X 18 /X. Perithecia scattered or in small groups, black, globular, 150 - 
180 diam., with a false ostiole formed of paler cells, verrucose ; bearing on 
the surface a number of sub-cylindrical, larviform appendages, terminating 
in a recurved point, 60-110 x 20-26 /x at the base, unicellular, colour 
russet-brown, wall rugulose. Asci ovoid, shortly pedicellate, 4-spored. 
Spores 3-septate, straight or slightly curved, similar in colour to hyphae, 
tawny olive (R. XXIX), slightly constricted at the septa, rounded at both 
ends, 40-45 x 13-14 /x.

Meliola natalensis Doidge n. sp. 
Amphigenous, mostly epiphyllous, forming round, irregular, black 
carbonaceous spots, 2-3 mm. diam. Mycelium radiating, branched; hyphae 
tawny olive {R. XXIX), somewhat sinuous and frequently constricted at 
the septa, 6-8 fi thick, composed of cells 14-18 /x long ; branches usually 
opposite. Capitate hyphopodia alternate or unilateral, stipitate, 18-21 /x 
long ; basal cell short, tapering to point of junction with hypha ; terminal 
cell broader than long, lobed usually with 2-3 lobes, which are again bi- 
lobulate, 12-14 x 16-20 /x. Mucronate hyphopodia rare, scattered, slender, 
straight or recurved, ca. 16-18 x 4-5 /x. Mycelial setae none. Perithecia 
grouped near centre of mycelium, black, globose, carbonaceous, 130-150 /x 
diam., rugulose, certain of the superficial cells being prolonged into sub- 
cylindrical vermiform processes 40-55 x 18 [x, sometimes recurved at the tip. 
Asci 2-spored. Spores 3-septate, cylindrical, deeply constricted at the septa, 
40-44 X 14-16 /X, straight or slightly curved, cells subequal.

Meliola conferta Doidge n. sp. 
Amphigenous, forming dull, black, sub-crustaceous colonies 1-3 mm. diam. 
Hyphae tawny olive (E. XXIX), straight, with numerous opposite branches, 
6-8 /X thick, composed of cells 11-18 /x long. Capitate hyphopodia very 
numerous, crowded together, opposite, occasionally, on the smaller branches.
