The epihymenium is brown and the overall hymenium measures approximately 115 microns in thickness. The thallus has numerous pycnidia with roundish 2-micron conidia and is K, KC and C negative via spot tests performed on sections under the compound scope. Apothecia slices placed in Lugol's and squashed stain red, so apparently hemiamyloid.
