A lichen with endolithic to thin and pale-coloured epilithic thallus, black lecideine apothecia, purple-black exciple and hypothecium and I+ red hymenium (Kilias 1981). It also has blueish pigment in the epihymenium (Svensson et al. 2017). The generic identity of the taxon is not clear due to the absence of molecular data, but based on morphological similarity, it currently belongs to the genus * Kiliasia* as K. tristis (Kistenich et al. 2018).
The lichen grows on shaded calcareous rock substrates, mainly in montane areas. It is recorded only scatteredly, rarely in central Europe. From the area of the Czech Republic, it is only known from the limestones in Rudník in Obří důl in the Krkonoše Mts, first published by Eitner (1901), later collected by V. Kuťák in 1924 (Kilias 1981) and recently confirmed by Z. Palice (Palice 2000, unpubl.).
Some records of the species from Norway refer to Bacidia coprodes (Svensson et al. 2017), a taxon with similar ecology and pigmentation but more septate ascospores. Both species grow in the Rudník locality. T. subnitida is, however, more easily confused with Lecidea hypochlorella Vain., from which it differs in pigments in the exciple/hypothecium and more septate spores (Svensson et al. 2017).
