Since 1844, vouchers of mycological specimens collected from the territory of the historic Baltic provinces of the Russian Empire have been preserved in Estonian natural history collections. A pedagogue and an amateur bryologist, Gustav Carl Girgensohn (1786–1872) compiled a collection of 109 specimens of fungi and myxomycetes sampled from the Livonian Governorate, mostly from the vicinity of Tartu, in years 1844–1859. Girgensohn’s collection, which is kept in the fungarium of the Estonian University of Life Sciences, is introduced here for the first time. Among his specimens there are two notable ascomycetes—coprophilous Poronia punctata (Xylariaceae, Sordariomycetes), recently evaluated in Estonia as Critically Endangered according to IUCN criteria, and Microstoma protractum (Sarcoscyphaceae, Pezizomycetes), recently evaluated as Endangered. The collection’s eleven quite well-preserved specimens of myxomycetes represent six species, the least common of which is Diderma radiatum. In addition, the article introduces nine lichen specimens and one fungal specimen from Girgensohn’s bryophyte collection at the Natural History Museum of the University of Tartu. The most remarkable species among this collection is Lobaria pulmonaria (Lobariaceae, Lecanoromycetes), red-listed and protected in many countries.
