Biatorella heterospora Kalb & Vězda
Lichenised.
Substrate: bark
Altitudinal distribution: montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)
Note: a corticolous species, peculiar in having a inspersed epihymenium with olive-blue granules, and ellipsoid ascospores of various shape; apparently rare (for the Alps reported only from Austria), and ecology therefore insufficiently known.
