GRAPHTS SCRTPTA 4 (1992)
C. ammiospila: t-4. This species, which was
formerly often recorded under the name
C. cinnamomea (Th. Fr.), Oliv., is widespread
in arctic and boreai regions of the
Northern Hemisphere (Hansen et al.
L987, SOchting 1989, Santesson 1984,
Egan L987). It was recently recorded from
Antarctica (SOchting & @vstedal l99Z).
Some of the material collected in Siberia
on lignum has affinity to C. spitsbergensis
H. Magn. The tanonomic status of this
species is however doubtful, and the
specimens may be only modifications of C.
ammiospila (SOchting 1989). C. spitsbrrgensis
was reported from Svalbard
(Magnusson 1944) and Greenland
(Hansen et al. 1987).
C. caesiorufella: l-4. Apparently widespread
in arctic, subarctic and boreal regions. It is
recorded from arctic Canada (Ahti et al.
1973), Greenland (Hansen et al. 1987, as
C. phaeocarpella), Svalbard (SOchting
1989), Scandinavia (Santesson l9S4) and
Siberia (Nylander 1885).
C. ceina: l, 2,4. Seems to be widespread in
the Northern Hemisphere, from where it
is recorded from a variety of substrates. It
is not known from Antarctica.
C. fraudans:1. This is an arctic species
previously recorded from North America,
Greenland, Svalbard, Scandinavia and
Novaya Zemlya (Magnusson 1944).
C. jungermanniae: l. An arctic-alpine species,
which is widely distributed over the
northern hemisphere and is recorded from
North America (Egan 1987), Greenland
(Hansen et al. L987), Svalbard (Lynge
1924), Scandinavia (Santesson L9S4) and
Siberia (Zhurbenko t99t).
C. lithophila coll. : 4. Specimens belonging to
the C. holocatpa group and growing on
rocks are presently little understood.
Accordingly any comments on distribution
has little meaning.
C. nivalis:1. This arctic-alpine species, is
recorded from North America (Egan
t987), Greenland (Hansen et al. l9B7),
Svalbard (Elvebakk I9g4), Scandinavia
Caloplaca in Siberia 31
(Santesson 1984) and Siberia (Zhurbenko
1ee1).
C. phaeocarpella: L, 3. C. phaeocarpella has so
far not been recorded from North America,
and is not with certainty identified
from Great Britain and Scandinavia. It is,
however, recorded from Greenland
(Hansen et al. 1987) and Svalbard
(SOchting 1989) and the holotype is from
the Kola Peninsula in Russia. It is previously
recorded from Siberia (Zhurbenko
lggL).
C. sibiricai 1, 4. Described by Magnusson
(L952) from Torne lappmark and arctic
Siberia. The holotype is from Minin Island
and additional specimens are from Taymir
Island, Cap Cheljuskin and Dudinka.
Hansen et al. (L987) were unable to trace
any material from Greenland, but it was
recently published from Svalbard
(SOchting 1989). The specimens from
Bennett Island grew on both moss and
lignum.
C, tetraspora: l-4. Appears to be a common
and widespread arctic-alpine species
which has been recorded from both the
Northern Hemisphere (Egan 1997,
Hansen et al. 1987, Santesson 1984, Lynge
L924, Zhurbenko 1991). It is also known
from Antarctica (Jakobsen & Kappen
1988, SOchtin g & Olech, unpublished).
C. tiroliensls: l, 2,4. This species is together
with C. tetraspora common in arcticalpine
areas of the Northern Hemisphere
(for references se under C. tetraspora). It
is also a common species in Antarctica
(Sochting & ovstedat t9g2).
C. torno€nsis: 1, 2. C. torno€nsb is recorded
from Northwest Territories, Canada
(Thomson & Scotter L984), from Greenland
(Hansen et al. L9B7), Svalbard (poelt
1969) and Scandinavia (Santesson 1984).
It is new to Siberia.
