The Herbarium at the Real Jardín Botánico contains the largest collection of dried fungi in the Iberian Peninsula. It is integrated by two collections, MA-FunHist and MA-Fungi. The first, houses the historical collection, i.e. those fungi included in the MA Herbarium until 1976. MA-Fungi collection contains nearly 85,000 specimens, of wich 194 are type specimens and 14,292 have microscope slides. Basidiomycota and Ascomycota (Kingdom Fungi), as well as Myxomycota (slime molds) are the best represented. This collection is the result primarily, of the activity developed by the staff of the Mycology research, initiated by F.D. Calonge in 1975, and specially by the research project Flora Micológica Ibérica (1991-2009), led by Mª. T. Telleria and M. Dueñas. The majority of the specimens are of Iberian origin, (85% from Spain
and 3% from Portugal
). The rest corresponds to specimens from other countries, mainly from Europe and America, but also from Asia and Africa, thoungh in smaller numbers, they are the result of exchanges programs and staff expeditions. Major collectors in the herbarium are: F.D. Calonge, M.T. Telleria, C. Lado, M. Dueñas, F. Pando, and M. Oltra. Private collections as the L. Cabo Rey and L.M. García Bona have recently included. The collection is fully databased using a system named “HERBAR”, a herbarium management program, developed by F. Pando et al. at Real Jardín Botánico.

Basidiomycota, with over 27,500 specimens is the divisio of fungi best represented, being corticioid fungi the most numerous, with more than 12,000 specimens; followed by agaricales, with nearly 9,950; gasteromycetes with 9,700, and poroid fungi with some 4,700 specimens. Most of them come from the Iberian Peninsula, but also there is a good representation of this group from France
, especially of corticioid fungi and also poroid fungi to a lesser extent.
The Myxomycetes collection with about 20.000 specimens, covers Iberian slime molds specially well. The Neotropics, as result of the Myxotropic project led by C. Lado, are also well represented. By groups, the collection comprises Physarales with 16,030 specimens, Stemonitales with 2,840, Liceales with 2,120 and in lesser number Echinosteliales and Ceratiomyxales. The collection of Myxomycetes of the MA herbarium, together with other four European Herbaria (BR, LE, M, and WARK) has participated in a research project with the aim of creating a virtual Herbarium of Myxomycetes through GBIF, consisting of 9,000 specimens, containing almost one third of all types of the group.
The Ascomycota are represented by 10,510 specimens, being the best represented orders: Pezizales, with 4.716 specimens, Erysiphales with 2,033, and Helothiales with 1,255.
