Abstract

Caloplaca maritime B. de Lesd. is a marine to maritime species occurring in western Europe. It was first described as a variety of C. citrina (Hoffm.) Th. Fr., but in 1953 was transferred to specific level. Since then C. maritima has been more or less forgotten and/or misunderstood, mainly due to confusion with C. ruderum(Malbr.) J. R. Laundon, C. interfulges (Nyl.) J. Steiner, and C. marina (Wedd.) Zahlbr. The present paper reports on the existence of C. maritima, and clarifies its status in relation to C. marina and to other related species. A map of the presently known distribution is presented and the species is depicted. Lectotypes for Caloplaca citrine var. maritime and C. citrine var. maritime f. laevigata are selected.
