Detailed description
Acervuli produced near the base of the leaf-like bracts that subtend each cluster of floral spiklets. They are linear, up to 1 mm long, black. This specific fungus has not been described. The conidia of Seimatosporium species are usually cylindrical, fusiform or clavate, straight or slightly curved, 2–5-septate, the end cells hyaline, with the middle usually cells brown. The apical cell and/or the basal cell may bear a single, simple or branched, appendage; some species lack an appendage. Seimatosporium, Pestalotiopsis, and Truncatella are morphologically similar genera, that all appear to occupy a similar niche on Desmoschoenus spiralis.
