Abstract:	The generic name Dactuliochaeta is established to accommodate Pyrenochaeta glycines, the causal agent of this disease and its synanamorph Dactuliophora glycines. The fungus is redescribed and illustrated from isolates originating from sclerotia on Neonotonia wightii or soyabean leaves or that were sieved from soil in Zambia. The genus is characterized by setose sclerotia which germinate to form mycelium and then setose pycnidia and/or pycnidia and sclerotia on their surfaces. The inner pycnidial walls are lined with ampulliform to lageniform, phialidic conidiogenous cells that are often periclinally thickened at the conidiogenous locus and bear uninucleate, hyaline conidia.
