Fellhanera viridisorediata Aptroot, M. Brand & Spier
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 usually epiphytic species with a granular, greenish grey, farinose-sorediate thallus containing roccellic acid, the soralia initially crateriform, later pustular and eventually fusing, the sessile apothecia rarely present, with dark brown discs and paler persistent margins, a paraplectenchymatic, hyaline exciple and a brownish hypothecium, 8-spored asci, and mainly 1-septate ascospores (14-17 × 3-5 μm) with a thin perispore; widespread in Europe, but most common in its western parts, with a single record from the Eastern Alps (Germany).
