GRAPHIS SCRIPTA 21 (2009) Lichens mainly known from Norwegian types 4 Aspicilia alexandri R.Sant. Type: Norway, Hedmark, Tronfjell, 1912, B. Lynge (BG!, lectotype of Lecanora zahlbruckneri Lynge, here selected). The original material, of which we have only been able to locate a specimen at BG, represents Aspilidea myrinii, a common and widespread species in our region, described from the mountains between Sogn and Valdres. Aspicilia austronorvegica (H.Magn.) Type: Norway, Vest-Agder, Lyngdal, Kvinesdalheia, 1939, A. H. Magnusson 16799 (UPS!, holotype of Lecanora austronorvegica H.Magn.). Like the former this also represents Aspilidea myrinii. The name has not formally been combined into Aspicilia. Aspicilia lecideoidea Hue Type: Norway, Dovrefjeld (collector and year not indicated, but probably Schimper 1844) (PC, holotype, non vidi). Since the type has not been located in PC, it is quite impossible to say what this name represents in spite of Hue’s detailed description (1910). It is even doubtful that it represents an Aspicilia in the present circumscription. Magnusson (1939) compares his new species Aspicilia austronorvegica with A. lecidoidea, so it may prove to be yet another synonym of Aspilidea myrinii. Anyway, rarity is certainly not the reason for the lack of other records, but rather doubts concerning the identity of the type. It is certainly not endemic to Dovre or Norway. Aspicilia mazarina (Wahlenb.) R.Sant. Type: Norway, Finnmark, Par. Tana, ad Kamiokaisse, 1802, G. Wahlenberg (UPS!, holotype of Lichen mazarinus Wahlenb.). This name has been incorrectly applied to members of the A. gibbosa group and was reserved exclusively for the type by Santesson (1984). However, Magnusson (1939) correctly suggested that it might be an aberrant form of Aspicilia aquatica, and thus the oldest name for this widespread, variable species. A conservation of the name Aspicilia aquatica against Lichen mazarinus has recently been proposed (Nordin & Jørgensen 2008). Aspicilia nordlandica (H.Magn.) Degel. Type: Norway, Nordland, Lofoten, Værøy, Guldakseln, 1922, G. E. DuRietz (UPS!, holotype, Fig. 4). TLC: norstictic acid. This is a well-defined species, according to Magnusson (1939) belonging to the cinereagroup, but with darker thallus, smaller apothecia and larger spores than A. cinerea. Further the paraphyses are distinctly nonmoniliform. The known distribution is restricted to Lofoten and the islands of southern Helgeland (Vega). The record from Sweden (LuL?) is certainly erroneous and no specimen to verify it has been located. It has in vain been Figure 4. Aspicilia nordlandica, part of holotype. Bar = Bar 0.5 mm.
5 Per Magnus Jørgensen & Anders Nordin GRAPHIS SCRIPTA 21 (2009) searched for in coastal regions further south (in Hordaland) and appears to belong in a most interesting, poorly understood phytogeographic element, also known from some flowering plants, well exemplified by Rorippa islandica (Oeder ex Murray) Borbas subsp. islandica (Jonsell 1968). That taxon is also known from Iceland, northern Scotland and Greenland as well as Switzerland. Aspicilia scabrida (Degel.) R.Sant. Type: Norway, Forsand, Frafjorddalen, Brådlandsfossen, N-sidan, 1947, G. Degelius (UPS!, holotype of Lecanora scabrida). TLC: norstictic acid. PMJ has in vain searched for this species in the region from where it was described, a region where he grew up. He only succeeded in refinding it on the very rock where Degelius originally collected it. This made him suspicious of its status. AN regards it as an extreme form of Aspicila epiglypta, a species which occurs rather frequently in this region. The spores are not as large as recorded by Degelius and falls well within the variation of A. epiglypta. Aspicilia subarctica (H.Magn.) Creveld Type: Norway, Troms, Karlsøy, N of Tromsø, 1861, A. J. Malmgren (UPS!, holotype of Lecanora subarctica H.Magn.). The specimen is best classified as part of the Aspicilia zonata complex (Nordin et al. 2007). See also under Aspicilia tromsoënsis below. Aspicilia tromsoënsis (H.Magn.) Räsänen Type: Norway, Troms, Karlsøy, N of Tromsø, 1861, A. J. Malmgren (UPS!, holotype of Lecanora tromsoënsis H.Magn.). It is highly unlikely that A. subarctica and A. tromsoënsis, both rare species, should occur in this little island which is not known to have a flora of particular distinction. Actually the type appears just to be a growthform of the former, as shown by Nordin et al. (2007). Bacidia luridoglaucella Vain. Type: Norway, Sogn og Fjordane, Stadtlandet, Ervik, 1903, J. J. Havaas (TUR-V 20822!, holotype). The description as well as well as the fact that Havås recorded some other specimes as Bacidina inundata from the same locality (Havås 1935), strongly suggested that this is just an aberrant form of Bacidina inundata, a fact that was confirmed by studies of the type (it had already been revised by S. Ekman). Bacidia verecundula (Th.Fr.) H.Magn. Type: Norway, Finnmark, Bossekop, 1864, Th. M. Fries (UPS!, holotype of Bilimbia verecundula Th.Fr., Fig. 5). This appears to be a well-defined but insignificant species, with hardly visible thallus and very small apothecia, certainly easily overlooked. Thomson (1997) also records it as exceedingly rare in Arctic America, also noting Figure 5. Bacidia verecundula, part of holotype. Bar = 0.5 mm.
