Lichenised.

Substrate: bark,

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: a species with an inconspicuous thallus, small (less than 0.2 mm in diam.), pale brown to bluish-grey, soon virtually immarginate apothecia, mostly 3-septate ascospores which are longer than 18 µm, and filiform, curved macroconidia (Fellhanera subtilis has ascospores shorter than 16 µm and pyriform-clavate conidia); usually on twigs and leaves (including needles of e.g. Abies) in the understory of forests, but also in semi-natural habitats; widespread in Western and Central Europe and Macaronesia; the occurrence in the Alps still insufficiently documented.
