The first records of Hypotrachyna lividescens and H. pseudosinuosa in the Iberian Peninsula

Hypotrachyna lividescens and H. pseudosinuosa are reported for the first time from the Iberian Peninsula, the second record of these species from Continental Europe. These lichens were found in a coastal area in the centre of Portugal, at Dunas de Quiaios, Figueira da Foz. H. lividescens was most commonly found on Halimium halimifolium, whereas H. pseudosinuosa was found mostly on Pinus pinaster. In addition, echinocarpic acid is reported as an accessory substance in H. lividescens for the first time
