Description

Conidiomata stromatic, acervulus, semi–immersed, beneath pale, erumpent and raised areas of host epidermis, central black ostioles, scattered or aggregate, spores scattered around the dehisce. Conidiophores reduce to conidiogenous cells, smooth, hyaline. Conidiogenous cells 13 × 6.5 µm, discrete, cylindrical to sub-cylindrical, smooth-walled, hyaline. Conidia 22–27 × 6–9 µm (x̅ ± SD = 24 ± 1.6 × 7.5 ± 1 µm, n = 40), fusoid, ellipsoidal to subcylindrical, 4-septate, straight to slightly curved; basal cell 2–6 µm long, semiellipsoid to obconic, or ampulliform, with a truncate base, hyaline, minutely verruculose and smooth-walled; three median cells 15–18 µm long, x̅ ± SD = 17 ± 1 µm, doliiform, versicolored, brown to pale brown, septa darker than the rest of the cell (second cell from the base 5–6.5 µm; third cell 5–6 µm; fourth cell 5–7 µm); apical cell 2.5–5 µm long, hyaline, conical to subcylindrical, smooth, thin- and smooth-walled; apical appendages 3–15 µm long, x̅ ± SD = 6.5 ± 2.8 µm, 1–3, tubular, arising from the apical crest, unbranched, filiform; basal appendage 2–4.5 µm long, single, tubular, unbranched, centric.
