Phylogeny and taxonomy of meristematic rock-inhabiting black fungi in the Dothideomycetes based on multi-locus phylogenies
2014
The last decade has revealed an unexpected
fungal diversityassociated with natural rocks, often collected in environments influenced by harsh climatic conditions. Yet the phylogenetic affiliations and the taxonomy of many of these extreme fungi, mainly within
Dothideomycetes, the largest class of
Ascomycota, have only partially been described. In the present study we confirm that most rock inhabiting-fungi (RIF) are highly polyphyletic among
Dothideomycetidae, mainly within the order
Capnodiales, an order otherwise incorporating several families of major
plant pathologicalimportance. Novel taxa were identified within the two major and distinct clades of
Teratosphaeriaceae, both comprising meristematic black fungi. Thirty one novel species and 13 new genera are proposed, based on ITS and partial nucLSU, RPB2 and BT2 sequences.
