Most recently there have been mycological explorations in Africa along with the discovery of some new Psilocybe species, including Psilocybe natalensis of South Africa and Psilocybe congolensis of the Congo. These species' uniqueness to their regions, along with other supporting evidence, are leading researchers to speculate that the species may have originated on the continent of Africa. Despite the lack of knowledge on mushroom use in Africa in recent history, cave paintings and etchings have been found that seem to depict humans consuming mushrooms. Mushrooms are also as symbols for certain families in some localities (Guzman et. Al. 2014). Archaeologists find that the genus Psilocybe may have originated between 10 and 20 million years ago in Africa (Froese et. Al. 2016). Hopefully further interest will be taken in African ethnomycology so that conclusions can be drawn from this evidence.
