Porella platyphylloidea (Schwein.) Lindenb.

The herbarium specimen (Hb De Notaris, RO), gathered by Bonnay in 1837 “ in valle augustana ” (AOS) corresponds to P. platyphylla (rev. M.A., 1993). The herbarium specimen (Hb De Notaris, RO) gathered by Cesati in 1837 “ ad Verbanum ” (PIE) corresponds to P. obtusata (rev. M.A., 1993). The herbarium specimens [TR] of Venturi for TRA (Rabbi e Nogaré) correspond to P. platyphylla (rev. R.S., 1994). The report for TOS (Montieri, Grosseto) by Murgia & Sassi (1982) is incorrect. The report for SAR (leg. Gennari 1858, Monte Sette Fratelli, sub Madotheca thuja, Hb De Notaris, RO) by Bertoloni (1858-62) corresponds to P. obtusata . The reports for LIG (De Notaris 1846), VEN (Trevisan, 1840) and LOM (De Notaris, 1859) appear dubious. At present, as shown by Therrien et al. (1998), P. platyphylloidea (Schwein.) Lindenb. is considered conspecific with P. platyphylla (L.) Pfeiff.
