The systematics of buellioid lichens is currently unclear. Several separate genera have been recognized but the circumscription of most of these is uncertain. The filiform conidia of B. gyspysensis suggests a placement in the genus Amandinea¸ which is separated from Buellia by this character, but molecular data suggests that taxa with character do not form a monophyletic group.
Known only from a single locality on a sea cliff on East Falkland (Falkland Islands)
Known only from a single location from the Falkland Islands, a sea cliff on East Falkland along Gypsy Cove. (AOO = 4 km2, EOO = 4 km2)
Known only from a single collection.
Known only from north-facing, rocky maritime cliffs on East Falkland
Further surveys to ascertain the extent of the population at its known locality and of suitable habitats elsewhere.
Buellia gypsyensis has not been discovered elsewhere among the c 5,000 collections from the Falkland Islands, nor in the c. 10,000 lichen collections from southern South America held in the herbarium of Michigan State University herbarium (MSC) so is evidently extremely rare. It is probably confined to the rocky, north-facing shores of the archipelago.
