Gheza, G., Nascimbene, J., Mayrhofer, H., Barcella, M. & Assini, S. 2018. Two Cladonia species new to Italy from dry habitats in the Po Plain. - Herzogia 31: 293–303.
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.
