69. Meliola Carissae n. sp. 
Amphigenous, forming irregular spots 5-6 mm. diameter or larger areas by confluence. 
Mycelium forming an irregular network, branches opposite, anastomosing. Hyphae 
slightly undulate, 6-7 » thick, not infrequently constricted at septa, cells 20-30 u long; 
capitate hyphopodia alternate, 20-30 « 10-13 u, terminal cell variable in form, sometimes 
club-shaped or sublobed, but most frequently truncate. Mucronate hyphopodia not very 
numerous, unilateral or alternate, with a short thick neck, 18-20 x 6-7 u. Mycelial setae 
fairly numerous, simple, straight, 550-700 u long, 9-10 u thick at base, and tapering very 
oradually to the blunt apex, black and opaque at base, but becoming brown and slightly 
translucent near apex. Perithecia not very numerous, 180-200 u diameter, spherical, 
black, surface cells slightly convex. Asci two-spored, evanescent, spores four-septate, 
oblong, slightly constricted, rounded at both ends, brown, 43-47 x 16°5-20 u. [Fig. 1.]

Meliola Carissae Doidge, nov. sp. 
Amphigena, maculas irregulares, 5-6 mm. diametro formans; hyphis subundulatis, 
6-7 uw crassis, nonnunquam ad septa constrictis, cellulis, 20-30 u long, ramis oppositis, 
anastomosantibus; hyphopodiis capitatis alternis, 20-30 “ 10-13 u, cellula superiore

lateralibus v. alternis, 18-20 « 6-7 u; setis mycelicis satis numerosis, rectis, simplicibus, 
550-700 u longi, basi opaco, 9-10 yu crassis, apice obtuse sensim attenuatis ; peritheciis 
180-200 u diametro, ascis bisporis ; sporis 4-septatis, oblongis, leniter constrictis, utrinque

70. Meliola dracoenicola Pat. et Har. 
Bull. Soc. Myc. Fr. XXIV (1908), p. 14, Sace. ; Syll. Fung. XXII, p. 56. 
On leaves of Behnia reticulata, Louis Trichardt, 8.5.19, Putterill [11848]. 
This fungus was originally described from the Congo on Dracoena sp.; it has not been 
previously recorded from South Africa. 
Amphigenous, black, forming spots 2-5 mm. diameter, easily detachable from the 
leaf surface. Hyphae brown, straight, 7-9 g thick ; cells 17-20 u long. :; branches opposite, 
numerous, anastomosing ; capitate hyphopodia alternate or unilateral, stipitate, 17-20 x 
10-13 u, stipe cell short, cylindrical, 5-7 » long, head cell globular ; mucronate hyphopodia 
numerous, alternate or opposite, interspersed with the capitate hyphopodia, pyriform or
