LICHALP

Arthonia cytisi A. Massal.

Syn.: Lecideopsis cytisi (A. Massal.) Dalla Torre & Sarnth.

Non- or doubtfully lichenised. Poorly known taxon.

Substrate: bark

Altitudinal range: from the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies) to the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)

Note: only known from the Italian Alps, on Laburnum, Fraxinus, Pinus cembra and Ribes, this non-lichenised species is worthy of further study.
