LICHALP

Leptorhaphis maggiana (A. Massal.) Körb.

Syn.: Campylacia maggiana A. Massal., Verrucaria maggiana (A. Massal.) Stizenb.

Non- or doubtfully 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 probably non-lichenised species with an inconspicuous thallus, numerous scattered ascomata, and 1- septate, slender ascospores with some 3-septate intermingled (30-45 × 1.5-2.5 µm), with attenuated ends; on the smooth bark of Carpinus, Corylus, more rarely of young Quercus (e.g. on twigs); widespread in Europe but rather rare and most records historical; from the Alps there are a few scattered records only.
