F. incarnatum is the oldest name available for the F. semitectum species complex (Leslie & Summerell 2006; Nirenberg 1990, etc). Isolates within this complex are morphologically and genetically variable but its taxonomy is yet to be resolved. For now F. semitectum and F. semitectum var. majus are placed in synonymy with F. incarnatum.
