Caloplaca ulcerosa, known as an epiphytic species growing on the bark of broad-leaved trees, is newly recorded from stems of maritime shrubs and from shaded limestone rock. In Europe, ninety-five percent of 90 considered records are within 50 km from a sea coast, but the species does not show any other geographical tendencies. It is rather regularly distributed throughout Europe, North Africa and the Near East. The distribution pattern of C. ulcerosa is, therefore, considered maritime it may be the first known example of a maritime distribution of a lichen generally growing on tree trunks. The remarkable occurrence in the Czech Republic with an abnormal ecology is discussed. The identity of the specimen is supported by molecular nrITS DNA data. Specimens called Caloplaca ulcerosa collected in the inland of North America are related but not conspecific with C. ulcerosa s. str. Caloplaca viperae, considered by Nimis a possible synonym to C. ulcerosa, is a blastidiate-isidiate taxon probably conspecific with C. herbidella.
