[1] It grows exclusively on foliose lichen species, including Lobaria pulmonaria and Nephroma arcticum.

The species was first discovered during studies of fungi growing on lichens in the western Pyrenees mountains of France and Spain.

The type specimen (holotype) was collected near Aspe peak in France at an elevation of 1,350 metres in a mixed beech-fir forest.

The upper wall of the catathecia is dark brown with a greyish tinge when treated with potassium hydroxide solution (K+) and is composed of rectangular or square cells arranged in radiating rows.

[2] In 2014, its known geographic and host range was expanded when it was reported in the Irkutsk region of Russia growing on Nephroma arcticum, and from Ecuador.
