The occurrence of arbuscular mycorrhizal fungi (AMF) in native (AN) and gypsum mining impacted (AI) areas in Araripina, Pernambuco State, Brazil, was determined using as trap cultures sorghum and peanut. The spores were morphologically characterized for identification at species level. DNA was extracted from spores and sequences of the ITS region used for molecular characterization. The molecular study confirmed the identification of three genera and four species (Funneliformis mosseae, Glomus sp., Glomus hoi, Claroideoglomus claroideum) that show ability to support stress conditions. Field work should be carried out to better understand the dynamics and functionality of these AMF species which could be selected for management programs in similar degraded areas.
