Abstract
Introduction Specimens of Sphaerocarpos collected during 2022 from the central Iberian Peninsula did not match any previously known species of this genus. Examination of other herbarium material revealed three identical specimens from three different localities in Spain. These were also morphologically identical to Portuguese specimens previously identified as S. stipitatus, a southern hemisphere and Himalayan species that in fact is different from these Portuguese plants.Methods The morphology of the newly collected specimens was compared with that of the known European species plus descriptions of South African plants of Sphaerocarpos stipitatus. A phylogenetic analysis based on the nuclear gene 26S and plastid psbA and rbcL regions was performed to investigate its relationships in the genus.Key results and conclusions Based on morphological and molecular data, we describe the plant as a new species of bryophyte, Sphaerocarpos ibericus M.Infante, Luceño, Quirós-de-la-Peña, Míguez, J.Muñoz & Heras, hitherto an Iberian endemic. It is diagnosed by having cylindrical female involucres with a partially bistratose wall whose inner cells are finger-like and arranged in more-or-less definite ribs in the medial part of the involucre, and the distal part of its spores covered with complete areolae larger at the centre of the spores than on their sides, gradually becoming incomplete and with the remaining lamellae transforming into ridges towards the line where the individual spores of the tetrad are joined. According to published illustrations, Portuguese specimens identified as S. stipitatus pertain indeed to the new species, and therefore S. stipitatus auct. eur. non Lindenb. should be removed from the European liverwort flora.
