An enlarged concept of Llimoniella (lichenicolous Helotiales), with a revised key to the species and notes on related genera

  • Paul DIEDERICH (a1), Damien ERTZ (a2) and Javier ETAYO (a3)

The new lichenicolous Llimoniella phaeophysciae, known from Italy, Spain and the USA (Arizona) on Phaeophyscia, resembles Geltingia associata in the subcylindrical asci with uniseriate, shortly ellipsoid ascospores, but is distinguished by several important characters. Gelatinopsis acarosporicola, G. heppiae, Geltingia groenlandiae and Psorotichia terricola (syn. nov. Gelatinopsis leptogii) are considered to be congeneric with L. phaeophysciae, although some of them have elongate clavate and not subcylindrical asci and they are consequently combined in Llimoniella. These five species are distinguished from Llimoniella s.str. by a different excipular and epihymenial pigmentation not reacting with KOH and are treated as the informal L. phaeophysciae group. The new L. placopsidis is described from Placopsis in New Zealand. More complex pigmentation patterns are documented for L. pyrenulae and L. ramalinae. A revised key to the species of Llimoniella is presented. Gelatinopsis ericetorum and G. roccellae are combined in Rhymbocarpus. A redescription of Geltingia associata is given.
