Since its resurrection, the resinicolous discomycete genus\ Sarea\ has been accepted as containing two species, one with black apothecia and pycnidia, and one with orange. We investigate this hypothesis using three ribosomal (nuITS, nuLSU, mtSSU) regions from and morphological examination of 70 specimens collected primarily in Europe and North America. The results of our analyses support separation of the traditional\ Sarea difformis s.l.\ and\ Sarea resinae s.l.\ into two distinct genera,\ Sarea\ and\ Zythia.\ Sarea\ as circumscribed is shown to comprise three phylospecies, with one corresponding to\ Sarea difformis s.s.\ and two, morphologically indistinguishable, corresponding to the newly combined\ Sarea coeloplata.\ Zythia\ is maintained as monotypic, containing only a genetically and morphologically variable\ Z. resinae. The new genus\ Atrozythia\ is erected for the new species\ A. klamathica.\ Arthrographis lignicola\ is placed in this genus on molecular grounds, expanding the concept of\ Sareomycetes\ by inclusion of a previously unknown type of anamorph. Dating analyses using additional marker regions indicate the emergence of the\ Sareomycetes\ was roughly concurrent with the diversification of the genus\ Pinus, suggesting that this group of fungi emerged to exploit the newly-available resinous ecological niche supplied by\ Pinus\ or another, extinct group of conifers. Our phylogeographic studies also permitted us to study the introductions of these fungi to areas where they are not native, including Antarctica, Cape Verde, and New Zealand and are consistent with historical hypotheses of introduction.
