Type species – Nigrocephalum collariferum (Weisenb. & R. Kirschner) Giraldo López & Crous

Notes – The monotypic genus Nigrocephalum was introduced by Giraldo & Crous (2019) to accommodate two isolates formerly described as Acremonium collariferum, which were isolated from the skin and nail lesions of humans. Nigrocephalum species can degrade keratin in vitro at 33 °C. The genus is characterized by erect, slightly bent, simple or basitonously branched conidiophores. Conidiogenous cells have a conspicuous funnel-shaped collarette and periclinal thickening at the conidiogenous locus. Conidia are ellipsoidal, concave in lateral view and pigmented (Giraldo & Crous 2019).
