The lichen herbarium at Tromsø Museum. This collection saw little activity before the year 2000. Much of the material is older, collected in northern Norway and on arctic islands by J. M. Norman, Bernt Lynge and other botanists working in the latter half of the 1800s and the first half of the 1900s. In many cases, specimens are also available in the lichen herbarium at the Natural History Museum in Oslo. The lichen herbarium also contains around 1000 specimens from Chile, Bolivia and Peru.
