Sorry, but I have to put this taxon back into the genus Racomitrium, because the other species are still listed under Racomitrium.
Hodgetts et al. 2020: The treatment of Racomitrium follows Larraín et al. (2013), who used molecular evidence for a broad treatment of the genus. Sawicki et al. (2015) used mitochondrial DNA to support narrower genera. However, they used only ten species of Racomitrium s.lat. (two from each segregate genus), and the results did not contradict the previous treatment. Indeed, significant problems remain (e.g. Bucklandiella sensu Ochyra is not monophyletic) and until Racomitrium s.lat. is more completely treated, we prefer to retain Racomitrium in a broad sense.
I will follow this way and unite everything under Racomitrium.

Unintended disagreements occur when a parent (B) is
thinned by swapping a child (E) to another part of the
taxonomic tree, resulting in existing IDs of the parent being interpreted
as disagreements with existing IDs of the swapped child.
Identification
ID 2 of taxon E will be an unintended disagreement with ID 1 of taxon B after the taxon swap
If thinning a parent results in more than 10 unintended disagreements, you
should split the parent after swapping the child to replace existing IDs
of the parent (B) with IDs that don't disagree.
