Meliola furcillata Doidge n. sp. 
Amphigenous, forming thin black spots 2-3 mm. diam. Hyphae straight 
or sinuous, tawny olive (R. XXIY), 6-8 thick, with opposite or unilateral 
branches, cells mostly about 18-21 /x long. Capitate hyphopodia alternate 
or unilateral, briefly stipitate 18-21'5/x long; terminal cell ovoid, straight, 
incurved or recurved 10'5-12'5 x 7-9 /x. Mucronate hyphopodia numerous, 
interspersed among the capitate hyphopodia, not on separate branches, 
14-18 /X long, ampulliform, with a rather long neck which is frequently 
curved. Mycelial setae more numerous in the neighbourhood of the peri- 
thecia, 330-400 x 7 /x, once or twice abruptly geniculate near the base, other- 
wise straight, more or less torulose, opaque at the base, more translucent 
and with a slight constriction below the apex, which terminates in a single 
mucronate point or is bi- or tridentate. Perithecia scattered or in small 
groups, black, globose, verrucose, 160-180 /x diam. Asci 2-spored. Spores 
4-septate, cylindrical, broadly rounded at both ends, constricted at the 
septa, 43-45 x 16-18 /x. 
On leaves of Maesa rufescens, Amanzimtoti, Natal, 10/7/11, E. M. Doidge 
(1573). 
Meliola varia Doidge n. sp. 
Amphigenous, forming small, black colonies 1-2 mm. diam. Hyphae 
sinuate, and irregular in thickness, 7-9 /x, argus brown (E. Ill) cells 18-25 /x 
long, branching irregular, usually alternate or unilateral. Capitate hypho- 
podia remote, not numerous, alternate or unilateral 21-25 /x long, terminal 
cell globular-ovoid, 14-16*5 x 10*5-12 /x. Mucronate hyphopodia very rare, 
paler, slender, tapering about 11 x 5-6 /x. Mycelial setae very numerous, 
180-220 /X long, lower part opaque 160-190 x 10 /x, above more translucent 
and branching m various ways, some dividing at once into 3 short branches 
about 18 /X long, others producing 2 thick, spreading branches 18-30 x 8 /x, 
each of these dividing into 2-3 smaller branches. Ultimate branches all 
bi- to trifid. Perithecia scattered, black, globose, collapsing slightly after 
drying, verrucose, 160-180 /x diam. Asci not seen. Spores 4-septate, 
scarcely constricted at the septa, cylindrical, rounded at the ends 45-50 x 
16-18 /X, middle cell sometimes larger than the rest.
