Meliola sp. (Fig. 2). 
On tlie same leaves as Meliola atra. There is also on these leaves a 
fungus belonging to the Trichopeltaceae and one belonging to the Hemi- 
sphaeriaceae, both immature, and a species of Asterina. The general habit of 
tlie Meliola is very similar to that of Meliola. Helleri Earle, which occurs in 
Porto Rico, but the setae are not forked as called for in the description of 
M. Helleri and the spores and hyphopodia diifer somewhat in size. 
Meliola cyUndripoda n. sp. 
Ampliigena, plerumque hjpophjlla, pelliculas tenues subindefinitas, 
nigras, 3-6 p. diam., formans, saepe plus minusve confluens ; mycelio inter- 
texta, pallide fusco ; hyphis 6-7 /x crassis, irregulariter undulatis, cellulis 
20-27 /X long., ramis oppositis ; hyphopodiis capitatis alternis v. unilater- 
alibus, breviter stipitatis, 12-16 x 6-9 /x ; cellula superiore cylindracea : 
liyphopodiis mucronatis paucis, oppositis v. sparsis, ampullaceis v. pyriformi- 
bus, 16 X 6—7 /X ; setis mycelicis parcis, simplicibus, rectis v. flexuosis, 300- 
500 /X long, basi 6-7 /x crassis, opacis, ad apicem pallidiorem paulatim 
attenuatis; peritheciis sparsis, globosis, minute verrucosis, 200-240 /xdiam. ;

Meliola ditricha K. &■ Cke. (Doidge). 
On Olea laurifolia Buccleuch (11615) and on Gymnosporia sip. Buccleuch 
(11572). This species w^as described from material collected by Medley 
Wood in 1876 C Trans. Eoy. Soc. S.A.,' vol. v, pt. 6, p. 728) on Celastrus 
sp. on w^hicli the perithecia were immature. Recent collections show 
abundant mature perithecia, they are 280-320 /x diam. and have conical 
chitinous appendages about 30-40 />t long ; these are more opaque than is 
usual in these peritliecial appendages. The form on Olea is more effuse and 
the hyphopodia somewhat larger (33-40 x 13-10 /x) than that on Celastrus. 
On Olea the fungus is usually heavily parasitised and does not often form 
perithecia. Meliola ditricJia has also been collected on Olea laurifolia at 
Tabankulu, Transkei, 15/3/15, by O. Fraser (M. H. 8888), and on Pleuro- 
stylia capensis, van Stadens Pass, 13/11/17, leg. E. M. Doidge (10883).
