and , two new apothecial dothideomycete genera and the new order .

During a survey on corticolous , several collections with ascospores matching the genera and (, ) were revealed from dead corticated twigs of , and . Closer morphological examination showed that their ascomata were apothecial, with a hamathecium consisting of septate, branched paraphyses, which are apically swollen at maturity. Several collections were cultured and sequenced, and a Blast search of their nuc 28S rDNA sequences revealed dothideomycetous affiliation, but without a close match to a specific family or order. Phylogenetic analyses of a multigene matrix containing a representative selection of from four genes (nuc 18S rDNA, nuc 28S rDNA, 2 and 1) revealed placement within but without a supported familial or ordinal affiliation. Based on the phylogenetic analyses and morphological investigations, the new genera and , with the two new species and , are described and illustrated, and placed in the new family and new order .
