Cladonia digitata (L.) Hoffm.

16: on several logs of Quercus robur (GG) .

An epiphytic and lignicolous species found in only one site in the river valley. C. digitata is tipically found in higher altitudinal belts in Italy ( Nimis, 2016) and is extremely rare in the Po Plain, where the only other record comes from an oak wood on the inland sand dunes of Cergnago, in the Eastern Lomellina ( Gheza et al., 2015). It was found together with other lignicolous species: Cladonia coniocraea (Flörke) Spreng. , Cladonia fimbriata (L.) Fr. and, in one case only, C. floerkeana (see below). Extremely rare.
