Description

Conidiomata eustromatic, superficial to slightly immersed, pulvinate to conical without necks, occasionally with a neck, orange when young, black when mature, conidiomatal bases above the bark surface 300-500 µm high, 200-1000 µm diam. Conidiomatal locules with even to convoluted inner surfaces, occasionally multilocular, locules 100-650 µm diam. Stromatic tissue pseudoparenchymatous. Conidiomatal locules multilocular, seldom unilocular, locules 30-500 mm. Conidiophores hyaline, branched irregularly at the base or above, with or without separating septa, (5-)8.5-13.5(-16) × 1.5-2.5 µm. Conidiogenous cells phialidic, determinate, apical or lateral on branches beneath a septum, cylindrical with or without attenuated apices, (1.5-)2-3 µm wide, collarette and periclinal thickening inconspicuous. Conidia hyaline, non-septate, oblong to cylindrical to ovoid, occasionally allantoid, (2.3-)3.1-3.5(-4.6) × (1-)1.5(-2) µm, exuded as bright luteous tendrils or droplets (Fig. 2 ).

Notes

Celoporthe guangdongensis was initially reported on Eucalyptus in Guangdong Province of China as a canker pathogen ( Chen et al. 2011). Two isolates from the present study cluster in a clade closely related to CMW 12750 (Fig. 3 ) and conidial dimensions measured in the present study fit exactly with those in Chen et al. (2011).
