It was described as new to science in 2003 by mycologists Dominique Claude Mossebo and Leif Ryvarden.
The type was collected in the Dja Faunal Reserve in Cameroon, where it was found fruiting on fallen dead hardwood branches.
[1] Mycorrhaphium africanum has a dimitic hyphal system, comprising generative and skeletal hyphae.
