LICHALP

Tephromela pertusarioides (Degel.) Hafellner & Cl. Roux

Syn.: Lecanora massalongiana Gyeln. non Zahlbr., Lecanora pertusarioides Degel.

Lichenised. Poorly known taxon.

Substrate: siliceous rocks

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: this may be a sorediate form of T. atra with an areolate thallus often devoid of apothecia, and with the same secondary chemistry; on siliceous rocks e.g. on cliffs in rather open forests; widespread in Europe but apparently rare; from the Alps there are only a few scattered records.
