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

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