A pioneer species, growing in humid forest microhabitats, such as ravines. It usually occurs accompanied by members of the genus Fellhanera. The lichen is easily overlooked since it often forms only small dark bluish pycnidia on a shiny thallus. Besides its usual occurrence on thin spruce twigs (including needles), it has been reported also from twigs and shaded smooth bark of deciduous trees, blueberry trunks, exposed roots, and slowly decaying wood. In the Czech Republic, the species has been reported mainly from the south-western part, from the Brdy hills, and from the northern sandstone area.taxonomic classification:
