A lichen with small, yellow to yellow-orange fruiting bodies and an inconspicuous thallus. Currently, it has been included in the genus Athallia. It is characterised by asci with 12 to 16 spores. It occurs on illuminated bark of various woody plants in nitrophilous communities of the Xanthorion alliance. It is abundant on twigs of deciduous trees in canopies. In the Czech Republic, it is widespread throughout the country, appearing from lowlands to mountains. However, it usually forms only scattered populations, so it may be easily overlooked.
