Differs from related Pestalotiopsis and Pestalosphaeria species mainly by its noticeably narrower, fusiform conidia with mostly a single apical appendage.

Colonies on PDA attaining 7 cm diam. after 7 days at 25° C, with edge undulate, whitish, aerial mycelium on surface, fruiting bodies black, concentric; reverse of culture yellow to pale brown. Conidiophores most often indistinct. Conidiogenous cells discrete, hyaline, simple, filiform, 4–10 µm long. Conidia 16–20 × 3–5 µm (x = 17.4 × 3.9 µm), fusiform, straight to slightly curved, 4-septate, smooth, greyish brown; basal cell conical, hyaline, thin-walled, 2–4 µm long (x = 2.4 µm); with three median cells, dark brown, concolorous, septa and periclinal walls darker than the rest of the cell, together 9.5–12 µm long (x = 11 µm); second cell from base 2.7–4.2 µm (x = 3.6 µm); third cell 2.4–4 µm (x = 3.3 µm); fourth cell 2.5–3.8 µm (x = 3.2 µm); apical cell hyaline, conic to subcylindrical, 1.8–3.6 µm (x = 2.4 µm); with 1–3 tubular apical appendages (mostly 1) without knobs, arising from the apex of the apical cell, 4–9.5 µm long (x = 6.6 µm); basal appendage filiform, short.

Etymology: —In reference to the host, Licuala grandis , from which this fungus was first isolated.
