Several established <i>Fusarium</i> species known to reside in the FIESC lack type material, further complicating the use of Latin binomials for this complex. To overcome this problem, an informal classification system based on a haplotype nomenclature was introduced to improve communication between researchers in various fields.

Species boundaries in the AVSC are unresolved since most species have uniform morphology and produce interspecific hybrids <i>in vitro</i>. Clinical and environmental strains from six continents (n = 110) were characterized by DNA sequencing of four to six loci. Biological compatibilities were tested within and between major phylogenetic clades, and ascospore morphology was characterised.
