fairly numerous usually on special short branches, opposite, ampulliform, 
tapering rather gradually to the neck, about 18 x 7 fx. Mycelial setae nume- 
rous, simple, more or less flexuose, opaque right to the acute tip, 260-300 x 
9-10 fx. Perithecia numerous, scattered, 160-200 /x diam., black, globose, 
very minutely verrucose. Asci not seen. Spores 4-septate, cylindrical, 
rounded at both ends, 45-55 x 16-18^. Conidiiferous mycelium paler and 
more slender, conidia borne on upright flexuose conidiophores, clavate, 3-5- 
septate, 50-70 x 6-10 /x.

This description, taken from Wood's duplicate of the type specimen, 
differs in many essentials from that given by G-aillard (Le Genre Meliola, 
p. 92). 
MacOwan (No. 1262) on leaves of Cunonia capensis approximates this 
species, but the specimens examined are parasitised hj Dimerium intermedium 
Syd., and no Meliola perithecia were seen. 
Meliola rigida Doidge n. sp. 
Amphigenous, forming rusty black colonies of varying size, sometimes, 
especially in the conidial stage, up to 1 cm. diam. Hyphae rigid, 7-8 jm thick, 
sepia-warm sepia (R. XXIX), composed of cells 18-25/^ long, branches usually 
opposite, hyphopodia very briefly stipitate, 14-18 /jl long, terminal cell globose 
or broadly ovate, sometimes slightly curved, 10-12 x 8-10/x. Mucronate 
hyphopodia not very numerous, paler, opposite, narrowed above into a short 
neck, about 18 /x long. Mycelial setae not very numerous, black, opaque 
almost to the acute apex, more or less flexuose, 250-600 /x long by 10-11 /x. 
Perithecia scattered, black, globose, verrucose, 180-220 jx diam. Ascus ovate, 
briefly stipitate, 3-spored. Spores 4-septate, slightly constricted, oblong, 
compressed, rounded at both ends, 40-45 x 16-20 jx.

Meliola falcata Syd. 
Annales Mycologici, vol. x, no. 1, 1912. 
Amphigenous, but most frequently epiphyllous, forming velvety black 
orbicular colonies 2~4 mm. broad, often confluent, and then irregular in 
outline. Hyphae snuff-brown (E. XXIX), anastomosing, 6-7 ft thick; capitate 
hyphopodia alternate, 22-25 /x long, apical cell up to 10 broad ; mucronate 
hyphopodia opposite, 15-18 fx long. Mycelial setae very numerous, simple,
