Cinco nuevos registros de liquenes marinos para Chile

Abstract

Five marine lichen species are reported for the first time in Chile: Arthopyrenia saxicola Massal., Caloplaca carphinea (Fr.) Jatta, C. thallincola (Wedd.) Du Rietz, Pertusaría rupicola (Fr.) Harm. and Xanthoria ectaenoides (Nyl.) Zahlbr. These were found at Bahía de Constitución, Central Chile. Descriptions of the material cover the external morphology of the thallus and the internal morphological characters of the reproductive structures. Colour photos of the thallus of all species are included, plus for some taxa we also describe chemical reactions of the thallus and of some reproductive structures.
