Neomyceta are fungi species which are non-native to a geographical region, and were introduced in recent history. The term is derived from the Greek neo = new and mykês = fungi. Fungi species are defined as neomyceta if they have been introduced after 1492, when Christopher Columbus arrived in the New World and the Columbian Exchange 1 began.
