University of Otago lichen expert Allison Knight alerted me to this taxonomic change, with this subspecies now being regarded as a distinct species.
See Hayward, G. C., Blanchon, D. J., and Lumbsch, H. T. (2014). Molecular data support Ramalina ovalis as a distinct lineage (Ramalinaceae, Ascomycota), The Lichenologist, (Vol. 46 (4))

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.
