The types of fungal names published by Ch. G. Ehrenberg from A. von Chamisso’s collection, and kept in the Mycological and Lichenological herbaria of the Komarov Botanical Institute (St. Petersburg, LE)
Lectotypes of twelve names of Fungi published by Christian Gottfried Ehrenberg from Adelbert von Chamisso’s collection (Auricularia cornea, Agaricus copulatus, Boletus katui, B. sector, Hypochnus nigrocinctus, Hysterium gracile, H. orbiculare, Naemaspora tularostoma, Sphaeria eschscholtzii, S. fur, S. profuga, Triblidium arcticum) are designated. It was thought that fungal collection made by Chamisso during the voyage around the world on board the Russian brig «Rurik» (1815–1818) had been lost, but many of his samples of fungi were re-discovered in 2013 in the Mycological Herbarium of the Komarov Botanical Institute (St. Petersburg, LE) including original material of ten Ehrenberg’s taxa. For Hypochnus rubrocinctus which was lectotypified earlier by Aptroot et al. (2009) the additional type material kept in the Lichenological Herbarium of the Komarov Botanical Institute (LE) is cited. It is supposed that original collections of Campsotrichum unicolor and Thamnomyces chamissonis may be kept in Fries herbarium (UPS).
