(2009): Lichens in Scandinavia known mainly from Norwegian type ...

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).

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
