Geographical distribution collection specimens

The Collection

The lichen collection of G. Lettau (1878-1951) at the Botanical Museum Berlin-Dahlem (B) comprises more than 17,000 herbarium specimens. The around 2,000 taxa represented are mainly from East Prussia (today Poland and Russia), Thuringia and the Black Forest mountains (Germany) and Switzerland, and were collected between 1898 and ca. 1940. A major part consists of epiphytic lichens, growing on trees and shrubs, which are particularly sensitive to environmental disturbance. The label information of the epiphytic lichens from Thuringia and the southern Black Forest has been databased as baseline information for the study of environmental changes.
