Interpretive Summary: Fusarium and its relatives are globally distributed fungi, found mostly in soil, living and dead plant material, air, and water. Species in this genus can be devastating plant pathogens, able to cause a wide spectrum of diseases on many important crops inducing cankers, diebacks, dry rot of roots and seeds, scab, wilt, and other diseases. These fungi are also capable of producing numerous mycotoxins that endanger animal and human health. The main goal of this work is to publish modern descriptions of important species, based on thorough microscopic examination, DNA sequences, ecological data, and novel resources including genomic data. These data will be available in an online database, which aims to provide a stable, regularly updated and user-friendly platform for the identification of Fusarium and related fungi. These data will be used by mycologists, plant pathologist, regulatory officials and extension personnel to identify pathogenic or exotic species.

Technical Abstract: Seven Fusarium species complexes are treated, namely F. aywerte species complex (FASC) (two species), F. buharicum species complex (FBSC) (five species), F. burgessii species complex (FBURSC) (three species), F. camptoceras species complex (FCAMSC) (three species), F. chlamydosporum species complex (FCSC) (eight species), F. citricola species complex (FCCSC) (five species) and the F. concolor species complex (FCOSC or FconSC) (four species). New species include Fusicolla elongata from soil (Zimbabwe), and Neocosmospora geoasparagicola from soil associated with Asparagus officinalis (Netherlands). New combinations include Neocosmospora akasia, N. awan, N. drepaniformis, N. duplosperma, N. geoasparagicola, N. mekan, N. papillata, N. variasi and N. warna. Newly validated taxa include Longinectria gen. nov., L. lagenoides, L. verticilliforme, Fusicolla gigas and Fusicolla guangxiensis. Furthermore, Fusarium rosicola is reduced to synonymy under N. brevis.
