Species Fungorum is a vital initiative coordinated by RBG Kew, dedicated to advancing the understanding of fungal biodiversity. As part of the global Species 2000 project, and in collaboration with ITIS, Species Fungorum contributes significantly to the Catalogue of Life, which is a critical resource within the GBIF portal. This platform offers users the ability to search through an expanding collection of taxonomically complete datasets, featuring global species databases.

Core services include access to the Dictionary of the Fungi, which provides consensus on fungal taxonomy up to the genus level, alongside comprehensive data on authors, publication sources, and type species. Additionally, the Bibliography of Systematic Mycology catalogs extensive literature on fungal biodiversity, classification, and systematics. The Index Fungorum serves as a global repository for fungal names across all ranks, with new data added quarterly. Species Fungorum welcomes contributions and suggestions from the scientific community to enhance its databases, fostering an ever-growing resource for mycology enthusiasts and researchers alike.
