Three new species of Arthoniales are described from Cape Verde: Ingaderia dendritica, with ascomata formed of richly branched-dendroid lirellae and containing erythrin; Sparria caboverdensis, with small stroma-like ascomata and ascospores with 3ā€“7 transverse septa; and Syncesia miesii, with an Iāˆ’ thallus, a tomentose hymenial disc, and a chemistry with fatty acids only. Phylogenetic analyses using nuLSU and RPB2 sequences reveal the placement of Fulvophyton sorediatum, Llimonaea occulta, L. sorediata and Sparria caboverdensis in the family Opegraphaceae. The genus Llimonaea is recovered as paraphyletic, with L. flexuosa being placed as sister species to a lineage including the genera Ingaderia and Paraingaderia. In consequence, an enlarged concept of the genus Ingaderia is proposed, resulting in the transfer of F. sorediatum, L. flexuosa, L. occulta, L. sorediata and Paraingaderia placodioidea to Ingaderia.
