Doidge (11608). 
Meliola sp. (Fig. 6). 
On leaves of Ochna airoimrpurea var. natalitia ; this is one of the large

only on Podocarjms latifolia in the Cape Forests (Knysna and George). 
Meliola sp. (Fig. 7). 
On Olea laurifolia ; on the same leaves as Meliola, amphitricha, and M. 
ditricha there is a third species of Meliola which clothes the petioles and 
also forms elongated colonies under the margin of the leaf ; on the petioles 
it forms a dense black mat which readily separates from the substratum ;
