Type species – Furcasterigmium furcatum (Moreau & V. Moreau) Giraldo López & Crous

Notes – Based on the phylogenetic analyses of combined LSU, ITS, tef1 and rpb2 sequence data from 20 isolates of Acremonium furcatum, Giraldo & Crous (2019) introduced Furcasterigmium for species of A. furcatum. This genus is characterized by erect conidiophores, often proliferating sympodially, with conidiogenous cells as short lateral and cylindrical asymmetrical projections. Conidiogenous cells are enteroblastic, mono- and polyphialidic, terminal, lateral, subulate, hyaline, with conspicuous collarette and periclinal thickening at the conidiogenous locus. Conidia are ellipsoidal, 1-celled, hyaline, smooth-walled and arranged in slimy heads (Giraldo & Crous 2019).
