In this case, the evidence against maintaining Royoporus seems reasonable. Molecular data place two species in Favolus and one in Picipes.
In general, I did get that impression. His considering Mycobonia in Cerioporus for instance seems obviously wrong.
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.
@jameskm Unfortunately, the works of Ivan Zmitrovich are mostly not very reliable and accepted in the scientific environment.
