The first annotated checklist of Costa Rican fungi

By this work, the first comprehensive checklist of fungi documented in Costa Rica is presented, developed through collaboration between local and international mycological experts. It is based on 866 publications documenting over 170 years of mycological research in the country, including approximately 9753 records and 5676 species and subspecific taxa across 1648 genera. The checklist provides detailed information on supraspecific taxonomic ranks, accepted species names with authors, synonyms with authors, and corresponding literature references. The list is available in two formats: a full taxonomic list organized hierarchically and a searchable Excel database. We expect this checklist to be a valuable resource for advancing mycology research in Costa Rica and the Neotropics.
