Pseudocryphonectriaelaeocarpicola gen. et sp. nov. (Cryphonectriaceae, Diaporthales) causing stem blight of Elaeocarpus spp. in China.

ABSTRACT: Cryphonectriaceae is a diaporthalean family containing important plant pathogens of which Cryphonectriaparasitica is the most notorious one. An emerging stem blight disease on Elaeocarpusapiculatus (Elaeocarpaceae) and E.hainanensis was observed in Guangdong Province of China recently. Typical Cryphonectria blight-like symptoms including cankers on tree barks with obvious orange conidial tendrils were observed. Forty-eight isolates were obtained from diseased tissues and conidiomata formed on the hosts E.apiculatus and E.hainanensis. These isolates were further identified based on both morphology and molecular methods using the combined sequence data of the internal transcribed spacer (ITS) region, large subunit of the nrDNA (LSU), the translation elongat
