Fungi from Asian Karst formations I. Pestalotiopsis photinicola sp. nov., causing leaf spots of Photinia serrulata

This is the first in a series of papers on the fungi growing on plants in the Karst formations of the Asian region. In this study, we collected leaf specimens of Photinia with numerous spots from Guiyang Botanical Gardens, Guiyang, China. A combination of morphological characters, together with analyses of combined ITS, TUB and TEF sequence data, distinguished the taxon as a new species of Pestalotiopsis. The new taxon is herein described as Pestalotiopsis photinicola and discussed in relation to the most related taxa.
