Neocosmospora E.F. Sm. 1899
This genus is widely distributed and includes around 70 species which are similar to Fusarium. However, Neocosmospora species form perithecia that are orange-brown to bright red and produce ascospores with no or 1 septa and are yellow-brown as well as finely striate. The species are saprobes, endophytes, plant pathogens, as well as pathogens infecting humans and animals. The taxonomy of these species was originally based on morphological characters and has only been clarified after detailed studies on their DNA structure. Many plant pathologists are not yet aware of these taxonomic changes and still used the Fusarium names.
Several species are economically very important plant pathogens that are soil borne and cause root rot and other diseases. The most important ones are Neocosmospora solani (previously Fusarium solani) and Neocosmospora phaseoli (previously Fusarium phaseoli and other forms). N. phaseoli includes also forms that cause the soybean sudden death syndrome (previously Fusarium virguliforme).
Type species: Neocosmospora vasinfecta
