The north American Lichen Checklist is the taxonomic authority on iNaturalist for lichens (from North America). It often cites both reports for lichens occurring in North America, and taxonomic works for name changes. Under Ricasolia, it cites two papers:

https://www.researchgate.net/publication/321056267_Ricasolia_amplissima_Lobariaceae_One_species_three_genotypes_and_a_new_taxon_from_south-eastern_Alaska
Esslinger didn't take up all changes suggested by that first paper; Anomalobaria, without which Lobaria s. str. has no support, he includes in Lobaria. Dendriscosticta and Ricasolia are accepted, though.
