Lecanora flavoleprosa Tønsberg

Lichenised.

Substrate: lignum, bark

Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) to the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)

Note: a species morphologically resembling L. expallens, with a greyish to yellowish thallus and soon confluent, pale yellow to yellow-green soralia (containing usnic acid, an unnamed xanthone and terpenoids including zeorin), apothecia occasionally present, of a dark aeruginose colour; on bark of various trees in all forest belts; distribution still incompletely documented. Earlier records from BE, LU, UW and VD in Switzerland refer to Lecanora compallens or L. strobilina.
