Morphological and phylogenetic analyses reveal new species and records of Fusarium (Nectriaceae, Hypocreales) from China.

Species of Fusarium are important phytopathogens, saprobes, and endophytes around the world. Some species can affect plant health and cause yield loss of economic plants. Fusarium species are widely distributed in China, and many species were found from different plant hosts. The Fusariumincarnatum-equiseti species complex (FIESC) is one of the most significant species complexes within the genus. Based on morphological and three-gene (cal, rpb2, and tef1) phylogenetic analyses, two new species are in the Incarnatum clade, and two new host records are identified and described, viz. Fusariumfici sp. nov., Fusariumxylosmatis sp. nov., Fusariumfecundum, and Fusariumweifangense.
