Differs from G-aillard's description of M. Hendeloti only in presence of 
mammillate cells on perithecium ; G-aillard puts this fungus in group " Peri- 
thecia smooth or simply granular," but in his description says " Perithecia 
rugulose." 
Meliola glabra Berk. & Curt. 
G-aillard, Le G-enre Meliola, p. 59. 
Amphigenous, but most frequently epiphyllous, forming black, crustaceous 
spots 2-3 mm. diam. Hyphae 7-9 /x thick, formed of cells 25-30 /jl long, 
Dresden brown (R. XV). Capitate hyphopodia alternate or unilateral, 
shortly stipitate, 18-25/x long ; terminal cell ovoid, globose, or slightly lobed 
11-14"5 X 11 /X. Mucronate hyphopodia ampulliform, about 14/x long, drawn 
out at the tip into a short, rather thick neck, not very numerous. Mycelial 
setae none. Perithecia grouped to the number of 8-10 in the centre of the 
colony, the superficial cells forming in places conical protrusions, rounded at 
the top, 150-180 /x diam., with a false ostiole at the summit. Asci ovoid- 
oblong, 2-4-spored. Spores 4-septate, constricted at the septa, rounded at 
the ends, 40-45 x 16-18 /x. 
On leaves of GantJiium sp., Woodbush, Zoutpansberg Dist., 3/8/11, E. M. 
Doidge (1780). 
This fungus differs slightly from the type described by Gaillard, the 
perithecia being smaller — he describes them as measuring 200-250 fx. Other- 
wise the description corresponds with his. 
Meliola Strophanthi Doidge, n.sp. 
Amphigenous, mostly hypophyllous, forming minute, black, sub-crus- 
taceous, orbicular-irregular spots 1-2 mm. diam. Hyphae somewhat sinuous, 
6-9 /X thick, composed of cells about 18 /x long, Brussels brown (E. Ill), 
branching'opposite. Capitate hyphopodia alternate, briefly stipitate, 20-25 /x 
long ; terminal cell cylindrical, straight to slightly curved, convex at the 
apex 16-18 x 7-9 /x. Mucronate hyphopodia not numerous, ampulliform, 
about 18 /X long, with a short neck. Mycelial setae none. Perithecia not 
numerous, in small groups, globular, black, 215-250 /x diam.; surface cells 
convex, rounded, conical. Mature asci not seen. Spores 40-45 x 16-18 /x, 
4-septate, very slightly constricted at the septa, cylindrical, broadly rounded 
at the ends. 
Conidiiferous mycelium interwoven with the perithecigerous hyphae, paler, 
hyphae thinner, with numerous dark brown erect conidiophores 180-200 /x 
long. Conidia fusiform, 3-septate, 18-32 x 5-9 /x. 
On the leaves of Strophanthus speciosus, Woodbush, Zoutpansberg Dist., 
3/8/11, E. M. Doidge (1781).
