The diversity of lignicolous agaric fungi is poorly known in Mexico. This group of fungi is responsible for the primary decomposition of wood, providing mineral elements that allow the nutrient cycles. The objective of this work was to reveal and confirm some lignicolous species present in Mexico with both morphological and molecular data. Thirteen species of eight genera, belonging to six families of lignicolous agaricoid fungi of the Agaricales were recorded, discussed, and illustrated, of which 11 are new records for Mexico. Considering our results, we confirm that Mexico is a Nearctic and Neotropical convergence zone of fungal taxa from both regions.
