KEYS TO THE LICHENS OF ITALY - 67) SCOLICIOSPORUM
The genus Scoliciosporum A. Masssal., now included in its own family Scoliciosporaceae, contains c. 15 species in temperate and subtropical areas. It somehow resembles Micarea, differing in the Lecanora-type asci, the large-celled photobiont, and the paraphyses with a dark cap. S. pruinosum deviates in several important characters, including ascus-type, and will be probably transferred to another genus. According to Miadlikowska & al. (2014), Scoliciosporum intrusum does not belong to this genus, and is better provisionally treated as a member of Micarea.
The present key includes all species of Scoliciosporum hitherto reported from Italy (Nimis 2016), plus a few species reported from neighbouring countries in the Alps (see Nimis & al. 2018), whose presence in Italy is probable, for a total of 8 species.
