Both Riccia plano-biconvexa and Riccia planobiconvexa currently exist on iNat and refer to the same taxon. GBIF has, apparently, applied Art. 60.9 of the ICBN to remove the hyphen in the epithet. Doing the same here to resolve the duplicate taxon entry. See flag https://inaturalist.org/flags/563246
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.
