Coryneum compactum  

Anamorph: conidiomata acervular, to 650 µm diam, scattered, not confluent, effuse to semi-pulvinate, erumpent through the outer periderm layers, the surface tissues above slightly domed but not obviously modified. Conidiomatal walls dark brown, composed of thin-walled vertically arranged pseudoparenchymatous cells, more irregular and thicker-walled at the base. Conidiophores to 30 µm long and 4 µm diam, branched at the base, cylindrical, septate, pale brown at the base. Conidiogenous cells formed as the apical cell of the conidiophore, not strongly distinguished, annellidic but often with only a single annellation. Conidia 40-55 x 18-22 µm, formed singly, broadly fusiform to fusiform-cylindrical or clavate (rather variable in form), tapered gradually or abruptly towards the obtuse apex, more gradually tapered towards the truncate base which often carries away part of the conidiogenous cell after succession, mid brown, smooth, distoseptate with 4-6 septa, the apical cell darker but with a hyaline tip, apparently without a gelatinous sheath or appendages.

Teleomorph: not known.
