Description:

Saprobic on bark. Asexual morph:  Conidiomata 180–500 μm high, 200–550 μm diam, pycnidial, subperidermal, separate, or in groups, immersed to semi-immersed in the bark of the host, globose or slightly depressed, with a central, inconspicuous ostiole. Conidiomatal wall 11–15 μm comprised a thick outer layer of textura angularis with dark brown cells and thinner inner layer of textura angularis-globulosa of yellowish to hyaline, thin walled cells, which gives rise to conidiogenous cells. Conidiophores reduced to conidiogenous cells.  Macroconidiogenous cells 8−15 × 8−10 µm (x̄ = 8.2 × 9.3 µm, n = 10), hyaline, discrete, holoblastic, annellidic, with 1 or 2 percurrent proliferations, broadly ampulliform to doliiform, with thick wall towards the apex. Microconidiogenous cells 14−16 × 2.9−3.8 µm (x̄ = 14.7 × 3.2 µm, n = 10), phialidic, holoblastic, non-proliferating, cylindrical to doliiform.  Macroconidia 35−38 × 16−18 µm (x̄ = 37.6 × 17.9 µm, n = 10), initially hyaline, elongated, ellipsoidal to cylindrical, broadly rounded at the apex, rounded and truncate at the base. Microconidia not observed. Sexual morph: Unknown.
