Meliola Toddaliae Doidge ii. sp. 
Amphigenous, forming black, circular, velvety spots 2-8 mm. diam., very 
easily detached from the leaf. Hyphae fuscous (B.. XL VI), much branched, 
7-10 /X thick, composed of cells 10-18 long ; branches usually opposite, less 
frequently unilateral, anastomosing, very pale near the tips. Capitate 
hyphopodia numerous, opposite, 18-20 /x long, stipitate; terminal cell usually 
sub-07ate and slightly in- or recurved, but often becoming flattened in 
various directions by compression, 14-16 x 8-10 /x. Mucronate hyphopodia 
not numerous, opposite, ampulliform, with a straight or curved neck, 
18-20 X 8-10 IX. Mycelial setae numerous, simple, straight, erect, at first 
translucent then becoming opaque almost to the acuminate apex, more or 
less torulose, 300-360 x 8-10 /x. Perithecia rather numerous, scattered, 
hidden among the setae, black, globose, verrucose, 200-250 /x diam. Asci 
3-4-spored. Spores 4-septate, slightly constricted, cylindrical, rounded at 
both ends, thick-walled, laterally compressed, 47-55 x 18-21 x 14 /x.

Amphigenous, forming very minute black colonies ^-1 mm. in diam. 
Hyphae slender, radiating, Isabella colour (R. XXX) 5-8 fx thick, composed of 
cells 20-35 /x long. Capitate hyphopodia distant, alternate or unilateral, 
stipitate, widening gradually from the base to just below the convex or 
rather pointed apex, 20-21*5 x 7-8 /x, terminal cell ovate, 14-16 /x long. 
Mucronate hyphopodia opposite, interspersed with the capitate hyphopodia, 
ampulliform, with a neck 5-7 /x long. Mycelial setae not numerous, more 
numerous in the neighbourhood of the perithecia, simple, somewhat abruptly 
geniculate near the base or incurved, 230-320 /x x 6-7 fi, very dark at the 
base, rather paler near the apex. Perithecia few, black, verrucose or rugu- 
lose, globular, 150-180 /x diam. Asci ovate, briefly pedicellate, 3-4 spored,
