Anamorph: not known.
Teleomorph: ascomata perithecia, immersed in dead rachides, singly or rarely in groups of two or three beneath a conspicuous clypeus. Clypeus 1.2-2 mm diam, flat, shining black, with the ostioles central and hardly protruding. Ascomata 800-1000 µm diam, ± globose but often irregular due to compression forces. Peridium 20-30 µm thick, composed of severla layers of flattened pseudoparenchymatous cells, the outer layers pale to dark brown. Interascal tissue of simple paraphyses, 2-3 µm diam, unbranched, apparently immersed in a gelatinous matrix (degraded in the material seen). Asci 250-300 x 9-11.5 µm, cylindrical, long-stalked (the sporiferous part 190-230 µm in length), fairly thin-walled, the apex rounded and thickened with a small apical ring, 8-spored. Ascospores arranged ± uniseriately, 26-32.5 (mean 28.7, sd 2.22, n=20) x 8-9.5 (mean 8.55, sd 0.51, n=20) µm, mean length/width ratio 3.37:1; narrowly ellipsoidal, the ends rounded or rarely ± acute, septate towards the base with the lower cell 3.5-5 µm in length, the upper cell chestnut brown and the lower cell pale brown to almost hyaline, thin- and smooth-walled, without a gelatinous sheath or appendages.
Not formally assessed, but would almost certainly be considered as Data Deficient. It has been reported only three times, twice from Sierra Leone in the 1940s and once from Tanzania in 1963. The host plant is very widely cultivated, providing ample habitat even if the species is strongly host-specific, but cultivation practices (spraying etc.) may have an effect on populations. The species is conspicuous and identifiable from external features, so the lack of reports could indicate rarity or even extinction.
Presumably saprobic, in dead rachides of Elaeis guineensis.
Only reported from Sierra Leone and Tanzania.
