LICHALP

Lecanora conizaeoides Nyl. ex Cromb.

Syn.: Lecanora conizaea auct. non (Ach.) Nyl., Lecanora conizaea f. variola Arnold, Lecanora farinaria Borrer var. conizaeoides (Nyl. ex Cromb.) A.L. Sm., Lecanora pityrea Erichsen, Lecanora pseudovaria Degel. nom. nud.

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 species with a sorediate thallus and apothecia usually present as well, reacting Pd+ red (fumarprotocetraric acid); on acid bark; in cities with severe air pollution it was often the only lichen that survived, more common in second half of the XX century in times of acid air-pollution, apparently becoming rarer and regionally even disappearing due nitrogen-rich pollution.
