El género Roccella DC. en México, está representado por tres especies, todas estas se encuentran distribuidas en las costas del océano pacifico. A pesar de que el estudio taxonómico de este liquen es relativamente reciente, se ha documentado que las culturas mesoamericanas usaban organismos de este grupo para la obtención de un tinte violáceo. Con el objetivo de conocer la probable existencia del género Roccella en el Golfo de México se realizaron visitas a las costas de Veracruz. Once especímenes fueron determinados como Roccella gracilis Bory. En este trabajo se hace el primer registro del género Roccella para las costas mexicanas del Golfo de México.Palabras clave: Arthoniales, Roccellaceae, Golfo de México, liquen. AbstractThe genus Roccella DC. in Mexico, it is represented by three species, all these species are distributed towards the Pacific. Although the taxonomic study of these species is relatively recent, it has been documented that Mesoamerican cultures used species of this genus in obtaining dyes. In order to know the probable existence of the genus Roccella on the coasts of Gulf of Mexico, visits were made to the coasts of Veracruz. Eleven specimens were identified as Roccella gracilis Bory. This paper represents the first report of the genus Roccella for the mexican coasts of the Gulf of Mexico.Keywords: Arthoniales, Roccellaceae, Gulf of Mexico, lichen.
