Mycobilimbia olivacea Aragón, Sarrión & Hafellner
Lichenised. Poorly known taxon.
Substrate: bark
Altitudinal distribution: montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)
Note: on bark, mainly of conifers, at the base of trunks. The Italian material differs from the description in the paler thallus and in not having biseriate asci. The species is likely to be related to Lecidea berengeriana.
