Rockefellera
Species of lichen
Rockefellera is a fungal genus in the family Pannariaceae. It is a monotypic genus, containing the single species Rockefellera crossophylla. The genus was circumscribed by James Lendemer and Erin Tripp in 2017. The generic name honors the Rockefeller family, "for their century-long support of North American conservation efforts, particularly with respect to national parks."[2]
Rockefellera crossophylla was originally described by American lichenologist Edward Tuckerman as Pannaria crossophylla, based on specimens he collected in New England.[3] He had previously mentioned the species in an 1859 publication by William Nylander,[4] but this was not a validly published name as a type was not indicated.[5]
Because of a dearth of records of the lichen from North America after its initial description, Per Magnus Jørgensen suggested in 2000 that it was potentially extinct in the wild on that continent.[6] Since then several populations have been reported from the Canadian Maritimes, the Ozark Highlands, and the southern Appalachian Mountains.[7][8]
