[3][4] In 1986, the species was moved to the genus Microdochium by Brian Charles Sutton, Victor J. Galea, and T.V.

[1] Microsclerotia present in past crop debris will germinate under wet conditions where it will produce hyphae to increase growth and conidiospores that release asexual conidia as a secondary infection; which increases the pathogen’s infection zone.

[6] Locations where this pathogen has been discovered include Alaska, Australia, Brazil, Bulgaria, California, Canada, Chile, China, Cuba, Denmark, the eastern United States, Florida, Greece, Idaho, Jamaica,  Libya, Mexico, Michigan, Missouri, New Zealand, North Carolina, Ohio, Oregon, Scotland, Serbia, Texas, Washington, and the West Indies.

Cultural controls can include elimination of prickly lettuce and other potential hosts from the vicinity of lettuce crops, sanitizing surfaces and equipment to remove soil and plant residue which may harbor the pathogen, destroying cull piles and discarded seedlings, and rotating crops.

Minimizing periods of leaf wetness aids in control of this pathogen, which requires free water for spore dispersal and germination.

[5][10] Chemical controls can include application of Badge SC or other copper products, mancozeb, and strobilurin fungicides.

[10] Recent research has shown that the fungus Trichoderma applied to soil or sprayed in a liquid filtrate onto leaves helps to prevent lettuce anthracnose and reduce symptoms when infection does occur.
