Sphaerocarpos ibericus sp. nov. (Sphaerocarpaceae), a new European liverwort species that includes S. stipitatus auct. eur. non Lindenb.

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.
