摘要：
Phoma odoratissimi sp. nov. on Viburnum odoratissimum and Syringa oblate, and Phoma segeticola sp. nov. on Cirsium segetum from China are introduced and described, employing a polyphasic approach characterising morphological characteristics, host association and phylogeny. Both species are the first records of Phoma species on their respective hosts. Multilocus phylogenetic tree was inferred using combined sequences of the internal transcribed spacer regions 1 & 2 and 5.8S nrDNA (ITS), and partial large subunit 28S nrDNA region (LSU), beta-tubulin (TUB) region and RNA polymerase II (RPB2) region. The two new species clustered in two separate and distinct lineages, and are distinct from their allied species.
