Terricolous lichens in particular are the most sensitive to threats, and have almost totally disappeared from the western Padanian Plain. This paper reports new findings of 20 terricolous lichen species, several of which are rare or poorly known in Italy or are of some phytogeographical interest because they are found at lower altitudes than their usual distribution (i.e. Cladonia coccifera, Cladonia uncialis). In addition, Cladonia humilis is new for Lombardy and two other species, Cladonia portentosa and Stereocaulon condensatum, are reported for the second time in the same region. The significance of these species is discussed with regard to their historical records from the same area and their current altitudinal distribution; they were probably much more widespread in the past, but the decline and disappearance of their habitats in lowland areas have been followed by their own disappearance in many localities. A modification of the rarity status of some of these species in the considered phytoclimatic belts, based on the new records, is proposed."

Two Cladonia Species New to Italy from Dry Habitats in the Po Plain / Gabriele Gheza in Herzogia, vol. 31, n°1 (Année 2018)

Public [article]  inHerzogia > vol. 31, n°1 (Année 2018) . - pp. 293-303 Titre : Two Cladonia Species New to Italy from Dry Habitats in the Po Plain Type de document : texte imprimé Auteurs : Gabriele Gheza, Auteur ; Juri Nascimbene, Auteur ; Helmut Mayrhofer, Auteur ; Matteo Barcella, Auteur ; Silvia Assini, Auteur Année de publication : 2018 Article en page(s) : pp. 293-303 Langues : Anglais (eng) Catégories : [ZG] Italie [habitats/milieux] 3 - Landes, fruticées et prairies [habitats/milieux] 31.2 - LANDES SECHES Mots-clés : biodiversité  lande à Calluna  association lichénique  communauté végétale  prairie sèche de Thero-Airion. Résumé : "Cladonia conista and C. pulvinata occur at several sites in dry lowland habitats in the Po Plain (northern Italy). Vegetation relevés are provided in order to characterize the main lichen associations (Cladonietum rei, Cladonietum foliaceae, Pycnothelio-Cladonietum cervicornis) and vascular plant communities in which the two species were found in Thero-Airion dry acidic grasslands and in dry open Calluna heathlands."
