The genus Acrophialophora is characterized by flask-shaped tapering phialides which are borne in verticils on unbranched, erect, darkly pigmented conidiophores or on undifferentiated aerial hyphae. Examination of the type culture of Paecilomyces fusisporus Saksena (1953) showed that this fungus belongs to Acrophialophora. Amongst some fungus cultures sent for identification to the CBS from Pakistan, Turkey, and Germany, a third species of Acrophialophora was found. Because of its smooth conidia the name Acrophialophora levis is proposed.
