GRAPHIS SCRIPTA 21 (2009) Lichens mainly known from Norwegian types 16 Figure 15. Verrucaria atlantica, part of isotype. Bar = 2 mm. alpine members of the group, and it seems to be phytogeographically misplaced, with no close relatives in the British Isles. It is accordingly crucial that it is searched for in the Stavanger region. The holotype in UPS has been mislaid. Verrucaria lyngei Servit Type: Norway, Finnmark, Kåfjord, Sakkobani, 1917, B. Lynge (not traced). The type has not been possible to trace, but in O there are two other specimens labelled (in Lynge’s handwriting) Verrucaria lyngei Zschacke, collected by Lynge in Voss, Lid in 1919. It has, however, not been possible to find Zschacke’s name published, nor is there any indication that Servit just took up an older herbarium name. So there is no evidence that Servit ever studied these specimens. Since Servit published the name after Lynge’s death it is impossible that Lynge had any knowledge of his name. Accordingly, the identity of this species, based only on the description, remains unclear, although there is an illustration to assist the interpretation. Verrucaria magnussoniana Servit Type: Norway, Akershus, Asker, Nesön, 1947, A. H. Magnusson (not traced). Though the type has not been traced there can be no doubt that Servit’s name is based on a duplicate of the holotype of the next name. Servit was evidently unaware of that Magnusson himself a few years (1948) before had published a name for this, so the name is a taxonomic synonym of Verrucaria osloënsis (for further comments see below). Verrucaria osloënsis H.Magn. Type: Norway, Akershus, Asker, S of Nesön (Nesøya), Djupalen islet, alt. 2 m, 17.VII.1947, A. H. Magnusson 20849 (O!, holotype) Magnusson (1948) compared this species with Verrucaria thromboides A.Massal., a rare lichen described from Italy. It would, however, have been closer at hand to check it against the related, better known V. macrostoma, which was already known from the region. We have not found any differences of taxonomic importance between the two of them, and without having studied the type or the variation on a larger scale, we think Magnusson’s species should be included in V. macrostoma, pending a revision of the whole group. Conclusion About 50 lichen species are known with certainty mainly from their Norwegian type specimens. We accept only a few (15) of these as distinct species (Table 1), most of which are certainly not endemic, except the two Lecidea species from the summit of Galdhøpiggen mountain. The others belong in difficult, poorly understood species complexes and are in need of further studies before their true status can be decided. Most of them appear to be dubious or synonyms of other accepted taxa, or indeed names that ought to be applied for more widespread species. We therefore suspect that the majority of these probable endemics will disappear after closer studies of fresh material, since it is highly unlikely that Norway has such a high number of endemic lichen species.
