Lumping Gemmabryum barnesii into Bryum dichotomum violates the recognized treatment in Volume 28, Flora of North America. In that treatment, Gemmabryum barnesii is recognized on page 133 |

Has it been proven that they are a single species?
In western North America, both species exist, are easily recognizable, and virtually never intergrade.
I do not agree with adding the Dutch common name ''Bryum barnesii J.B. Wood ex Schimp. ---- Geelkorrelknikmos'' to this species and I expect it is related to lumping both species to one species.
was Gemmabryum dichotomum changed back to bryum dichotomum? if so where is the referance?
@mossgeek it looks like @tayloria did that here: https://www.inaturalist.org/taxon_changes/81466
Bryum barnesii is usually regarded as a distinct species, but many plants and populations intermediate between Bryum barnesii and Bryum dichotomum occur (Holyoak 2003).
