Description
The lichen herbarium TROM, The Arctic University Museum of Norway (former Tromsø Museum) contains c. 22 500 specimens.
Much of the material is old and was collected in Northern Norway and from the Norwegian Arctic islands by J. M. Norman, Bernt Lynge and other botanists during the latter half of the 19th century and the early 20th century. The collection has increased during our own research activity during recent decades, with important additions from Southern Hemisphere areas, such as Chile, New Zealand, Australia, Bolivia, New Caledonia, Reunion, Bouvet Island and Antarctica . TROM may now have one of the world largest collections (c. 1 800 samples) of the Pannaria/Psoroma complex within the family Pannariaceae and has a number of type specimens.
