I have therefore described the former as a variety of M. geniculata. 
The descriptions of these fungi are as follows : 
Meliola malacotricha Speg. 
Sacc. Syll. Supp. Univ. i, p. 425. 
G-aillard, Le G-enre Meliola. 
Mostly hypopliyllous, forming round or irregular spots 1-4 mm. diam., 
often confluent and covering a great part of the leaf surface. Hyphae 
brown, 5-7 /x thick ; composed of cells 25-30 /x long ; branches opposite ; 
capitate hyphopodia opposite, alternate or unilateral, 14-16 x 7-10 /x, briefly 
stipitate, terminal cell ovoid or globular ; mucronate hyphopodia interspersed 
with the capitate hyphopodia, opposite, narrow-ampulliform, 12-15 // long. 
Mycelial setae fairly numerous, incurved and bent at right angles at the 
base or at some other point in their length, becoming insensibly narrower 
towards the translucent apex, 150-300 x 5-10 /x. Perithecia in small groups 
in the centre of the spot, globular, then depressed, black, minutely verrucose, 
150-220 fx diam. Asci 2-spored. Spores 4-septate, cylindrical, straight or 
slightly curved, slightly constricted at the septa, and slightly attenuated 
towards the rounded extremities, 30-38 x 12-15 /x. 
On Indigofera sp., Buccleuch, Natal, 23/3/16, E. M. Doidge (9703). 
On Baphia racemosa, Sea View, Durban, 1/10/17, P. v. d. Bijil 
(Natal Herbarium No. 783) (11354). 
In both these specimens the majority of the spores fall within the 
dimensions given above, but a few are longer, up to 42 /x. 
Meliola hicornis Wint. 
Gaillard, Le Grenre Meliola, p. 99. 
Colonies black round-irregular, scattered or confluent, sometimes up to 
8 mm. diam. Hyphae slender, 6-7 /x, spreading, laxly branched, flexuose, 
somewhat torulose. Capitate hyphopodia opposite, alternate or unilateral, 
small 12-15 /x x 7-10 /x ; basal cell very short, 3-5 /x, enlarged at the base, 
terminal cell globular. Mucronate hyphopodia interspersed with the capitate 
hyphopodia, usually opposite, ampulliform, drawn out into rather a long 
neck. Mycelial setae rather numerous, slender, brown, translucent, with 
numerous septa, divided at the apex into 2 (occasionally 3) simple or 
forked acute branches. Perithecia scattered over the whole colony, globular, 
then depressed, scabrous, 120-160 /x diam. Asci ellipsoid with a very short 
foot, with 2-3 or 4 spores. Spores 4-septate, slightly constricted at septa, 
brown, broadly rounded at both ends, 37-45 x 12-15 jj,. 
On leaves of Oncinotis i7ianclensis, Buccleuch, Natal, 23/3/16, E. M. 
Doidge (9722).
