Cystoderma freirei, une nouvelle espèce découverte en Galice (Espagne)

While studying the herbarium specimens of Cystoderma deposited in the LOUFungi herbarium at Lourizán (Spain), three collections were studied for which no satisfactory identification could have been done. After a careful comparison with the descriptions of the known species of Cystoderma, we concluded that of our specimens represent an undescribed species, which we propose to name here Cystoderma freirei.
