Anamorph: conidiomata acervular, 500-900 µm diam., visible from the substratum surface only as inconspicuous mounds of ejected conidia; inserted within the upper bark layers, the wall composed of hyaline to pale brown thin-walled angular cells. Ostiole absent, dehiscence by irregular rupture of the surface layers. Conidiophores to ca 40 µm long and 2-2.5 µm diam., cylindrical, septate, branched at the base, formed from the inner layer of the basal wall and interspersed with paraphysis-like sterile hyphae to ca 100 µmm long and 2 µm diam. Conidiogenous cells not strongly differentiated, formed as the apical cell of the conidiophore, cylindrical, hyaline, smooth, thin-walled, proliferating percurrently with 1-3 closely spaced annellations, with a minute collarette but periclinal thickening absent or inconspicuous. Conidia (29-) 30-33.5 (-35) x (8-) 9-10.5 µm, cylindric-ellipsoidal to fusiform-ellipsoidal, the apex acute to obtuse and the base narrowly truncate, fairly thick-walled, smooth, blue-grey in colour, without a gelatinous sheath or appendages. Teleomorph: not known.
