Fellhanera colchica, relocating a forgotten taxon, and Byssoloma llimonae new for Italy

Abstract

The foliicolous species Bacidia colchica Vězda was described from the eastern coast of the Black Sea (Vězda 1979, 1983) and is also known from SW France (Sérusiaux 1989; Sérusiaux et al. 2002) and S Italy (Puntillo 2000; Puntillo et al. 2000). However, its morphological features, such as the structure of the exciple, morphology of the paraphyses and ascus type, do not fit the current concept of Bacidia De Not. (Ekman 1996, 2001) but place this taxon in the Pilocarpaceae. The current circumscription of Pilocarpaceae is still under discussion, as well as the concept of some genera at present included in this family (Sérusiaux 1993; Lücking et al. 1994; Kalb et al. 2000; Lücking et al. 2001a; Sérusiaux et al. 2002; Andersen & Ekman 2005). In particular, the position of B. colchica should be in Fellhanera Vězda (Vězda 1986; Lücking et al. 1994; Sérusiaux 1996; Lücking 1997). Although several recent works have dealt with the European species of the genus Fellhanera (Sérusiaux 1996; Aptroot et al. 1998; Sparrius & Aptroot 2000; Sérusiaux et al. 2001; Sparrius 2002; Spier et al. 2002), none of them included B. colchica, despite some of the papers considering foliicolous taxa.
