LICHALP

Naetrocymbe laburni (Leight. ex Arnold) ined. (provisionally placed here, ICN Art. 36.1b)

Syn.: Arthopyrenia laburni Leight. ex Arnold

Non- or doubtfully lichenised. Poorly known taxon.

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 probably non-lichenised species resembling N. fumago in the thallus indicated by dark patches, but the 1-septate ascospores virtually narrower due to their length (18-22 × 3-4 µm); on smooth bark, especially of Laburnum.
