Syn.: Pertusaria glomerata (Ach.) Schaer. var. octomela Norman
Lichenised.
Substrate: bark
Altitudinal distribution: montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)
Note: similar to P. glomerata and in the typical strain also with the same secondary chemistry (norstictic acid), but asci 8-spored and ascospores smaller; a second strain contains stictic acid and xanthones; on soil and plant debris, more common in the subarctic to boreal-subalpine zone, with a single record from the montane belt of the Eastern Alps (Austria).
