The state of Veracruz integrates 12 vegetation types and diverse ecosystems. However, the richness, and completeness of arbuscular mycorrhizal fungi (AMF) inventories by vegetation type are unknown in Veracruz. Our objectives were (i) to gather a checklist of the AMF from the literature review to recognize AMF distribution according to biotic provinces, and (ii) to estimate the richness of the agroecosystems and natural vegetation in the state of Veracruz, using rarefaction and extrapolation curves. We compiled 130 AMF species belonging to 6 orders, 12 families, and 29 genera, reported from five natural ecosystems, and agroecosystems based on 27 published scientific papers. The highest AMF richness was associated with agroecosystems (116 spp.) followed by tropical deciduous forest (13 spp.) and coastal dunes (8 spp.). Rarefaction curves estimate 168 species (92 coverage) of AMF. Although this is a conservative analysis, it places Veracruz as the state of Mexico with the highest richness of AMF.

Keywords: Glomeromycota, extrapolation curves, richness estimation, biotic province.
