Lesions: hardly differentiated, sometimes with a small slightly discoloured area surrounding the stromata and the leaf surface immediately below browned.
Stromata 400-950 µm diam, usually solitary, circular to widely elliptical but often rather irregularly shaped in surface view, 2- to 9-loculate, sometimes following veins, epigenous or hypogenous, shallowly domed with the individual ascomata sometimes visible from the surface, shining black, the ostioles inconspicuous, not papillate.
Anamorph: not known.
Teleomorph: Ascomata 250-350 µm diam, globose to oblate, the upper part shallowly conical, with a well-developed clypeate upper wall composed of a thick outer layer of leaf epidermal and palisade cells completely occluded by strongly melanized fungal cells intermediate between textura angularis and globulosa, merging into a mid brown inner layer 12-18 µm thick of flattened thin-walled fungal cells which extends competely around the ascomata. Periphyses well-developed, to 20 µm in length, with a mucous coat, merging with the paraphyses. Paraphyses to 4 µm diam, very thin-walled, gradually tapering, remotely septate, without a mucous coating. Asci sometimes arranged centripetally, 98-132 x 12-14.5 µm, cylindric-clavate, fairly long-stalked, thin-walled at all stages, the apex obtuse, ? with a small very inconspicuous ring, 8-spored. Ascospores usually partially biseriately arranged, (18-)21-25.5 x 4.5-6 µm, hyaline, smooth and fairly thin-walled, with one weakly constricted median to slightly submedian septum, the upper cell ± cylindrical with a rounded end, the lower often slightly tapered and obtuse-ended, surrounded by an inconspicuous gelatinous sheath to 4.5 µm thick.
Host species: Albizia spp. Known from Albizia adianthifolia (syn. A. fastigiata), A. gummifera (syn. A. sassa), A. heterophylla and A. zygia.
Distribution: Recorded from Ethiopia, Ghana, Guinea, Kenya, Malawi, Réunion, Sierra Leone, South Africa and Zambia.
