Morphological and phylogenetic characterisation of two new species of Phyllosticta from China

Phyllosticta styracicola sp. nov. on Styrax grandiflorus from Xishuangbanna Tropical Botanical Garden, Yunnan province, China, and Phyllosticta hubeiensis sp. nov. on Viburnum odoratissimum from Shennongjia forest, Hubei province, China, are described and illustrated in this paper. Phylogenetic analysis based on nrDNA-internal transcribed spacer (ITS) and a combined multi-locus alignment of the ITS, partial translation elongation factor 1-alpha (TEF1), actin (ACT) and glyceraldehydes-3-phosphate dehydrogenase (GAPDH) gene regions indicated that these two species were closely related to P. ampelicida and P. gaultheriae respectively. Justifications of the novelties of both species are provided.
