Substrate: calciferous soil, acidic soil (mostly on siliceous substrata)
Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) to the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)
Note: an inconspicuous lichen with a blackish-grey thallus composed of goniocysts containing a nostociform photobiont, and convex, virtually immarginate, colourless to medium brown (when dry) apothecia with cylindrical to subclavate asci recalling those of Trapelia, containing simple, relatively large ascospores; pioneer on soil and debris e.g. on dump heaps and margins of white roads; widespread in the boreal to temperate zones of Europe, but rare (perhaps overlooked), in the Alps, being only known from a single locality.
