Abstract: 67 fig. ["The typification of the 109 names of lichens described by Linnaeus is discussed; 50 lectotypes, 24 epitypes and eight neotypes are newly designated. All written sources of which we are aware have been consulted, including original manuscripts. The relevant specimens in Linnaeus' lichen herbarium (LINN) have been carefully evaluated. All these elements are discussed, as well as the validity of previous typifications. Most names (72.5%) can be typified in a way that avoids any changes in their current interpretation, but proposals for conservation are necessary for 17 species names if their current usage is to be upheld. Six Linnaean names which have not been in use for a long time are treated as species non satis notae since no original material has been traced and the protologues are too vague to allow the species names to be identified with certainty. They will be proposed for rejection under Art. 56 of the Tokyo Code together with five names - Lichen cornucopioides, Lichen fahlunensis, L. plicatus, L. rangiferinus var. sylvaticus and Mucor lichenoides - the typification of which has unfortunate nomenclatural consequences." In addition to photographs of many of the type specimens, a photographic reproduction of Linnaeus' original working manuscript of the genus Lichen for Species plantarum (1753) is included.]
