@kueda - yes I am - we will update at our end accordingly. Another example of being isolated from the world and the New Zealand treatment of Usnea needs a major overhaul.
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.
@pjd1, here's one where NZ Plants supports U. wirthii, while Esslinger does not, due to the paper linked above. Are you ok with this change?
