- Paraboeremia was recently introduced for a distinct lineage in the family Didymellaceae. Currently, three species are included, i.e. P. adianticola, P. putaminum and P. selaginellae, all of which are plant pathogens. Paraboeremia is morphologically similar to Phoma but phylogenetically distinct. In this paper, three new species, i.e. Paraboeremia camelliae isolated from Camellia sp., P. litseae from Litsea sp., and P. oligotrophica from cave limestone, are described, illustrated and compared with closely related taxa. Phylogenetic analysis based on the multi-locus sequences of the internal transcribed spacer regions 1 and 2 and 5.8S nuclear ribosomal RNA gene (ITS), partial large subunit 28S nrDNA region (LSU), partial β-tubulin (TUB2) gene and RNA polymerase II (RPB2) gene regions confirmed the distinction of these species in Paraboeremia. These three new species were discovered from habitats and hosts that are previously unknown from this genus.
