I doubt many people agree on varieties and subspecies, considering that they can’t even figure out what the species is. But this particluar one appears on MycoBank and IndexFungorum, among other things, so at least some people, other than Thomson, consider it legitimate too.
Never heard of this variety. It’s not even on Esslinger’s checklist for North America. I’d say you’re overdue for that Nobel’s prize. :)
“When on Betula its apothecia seem to be influenced by the bark texture to become elongate and parallel with such a characteristic appearance that it is often identified as var. topographica (sic.)(Willd)Zahlbr”.
