This species is highly unusual among the genus due to its foliicolous, Strigula-like, subcuticular thallus. Sérusiaux and Aptroot (1998) already discussed the possibility of this being a lichenicolous fungus on a Strigula thallus, but found no support for this hypothesis. The anatomical characters of the ascomata and asci are reminiscent of the lichenicolous genus Polycoccum Saut. ex Körb. (Matzer 1996; Diederich et al. 2018), which has recently been identified as a close relative of Trypetheliaceae (Ertz et al. 2015). We refrain from proposing any taxonomic changes at this point but we predict that this taxon is not a genuine Trypetheliaceae.
