Hyväksytty nimi,

The status of this taxon is uncertain. The European checklist (Hodgetts et al. 2020) does not recognise this taxon, since Holyoak (2004) shows that there are intermediate forms between Bryum intermedium and Bryum nitidulum. However, we follow tropicos.org and The World Flora Online which state that Ptychostomum nitidulum is an accepted taxon in North America.
