Meliola Bosciae Doidge n. sp. 
Epiphyllous, rarely hypophyllous ; forming a thin, black, sub-orbicular 
pellicle 2-3 mm. wide on the leaf surface. Hyphae radiating, frequently 
anastomosing in the neighbourhood of the perithecia, tawny olive (R. 
XXIX), septa at times curved, vermiculate, 5-5-9 /x thick; branches 
opposite or unilateral. Capitate hyphopodia alternate or unilateral, rarely 
opposite, shortly stipitate, 14-20 /a long ; terminal cell 10-5-16 fx long, 
scabrous, convex, truncate or slightly lobed. Mucronate hyphopodia most 
numerous in the neighbourhood of the perithecia, on separate branches or 
scattered amongst the capitate hyphopodia, opposite or unilateral 14-18 fx 
long and about 7 /x thick at the base, ampulliform, with a long neck which 
is frequently incurved. Mycelial setae none. Perithecia globose, black, 
verrucose, 160-180 /x diam., with 6-12 setae scattered on the surface. Setae 
simple, 70-90 /x long, opaque, and about 6 /x thick at the slightly bulbous base, 
and tapering to the obtuse pellucid apex, straight, or abruptly bent just 
behind the apex. Ascus 2-3-spored, ovate, shortly pedicellate, evanescent. 
Spores sepia colour (R. XXIX) 4-septate, constricted at the septa, rounded 
at both ends, 39-47 x 10-5-14-5 /x.

Branches widely divaricating. Capitate hyphopodia opposite, numerous, 
10*5-15 /X long, widely divaricating, regular ; terminal cell 9-10 x 7-8 /x, 
basal cell about 3-5 x 6-7 /x. Mucronate hyphopodia opposite, numerous, 
14-18 /X long. Mycelial setae straight, simple, opaque, 300-400 x 5-10 /x, 
pellucid near the acute apex. Perithecia gregarious, black, globose, verru-
