“…Therefore, the division into Catapyrenium for non-septate taxa and Placidiopsis for uniseptate taxa seems arbitrary, and the fusion of these two genera can be envisaged. However, Breuss & Hansen (1988) also noticed that the septation in Placidiopsis ("true" septa) was different than the one in Catapyrenium (pseudosepta). The monophyly of both genera Catapyrenium and Placidiopsis is, therefore, still an open question.…”

“…Although both Catapyrenium and Placidiopsis appear to be monophyletic (but only two species of each genus were included; see Fig. 3), the recognition of these two genera has already been criticized in the past (Breuss & Hansen, 1988;Breuss, 1996b). The only character separating them is the presence of a transversal septum in the spores of Placidiopsis.…”

Recent molecular phylogenetic analyses and morphological studies have shown that it is necessary to revise the present morphology-based generic delineation of the lichen family Verrucariaceae in order to account for evolutionary relatedness between species. Consequently, several genera were recently described or resurrected, and others were re-circumscribed. As an additional step toward this generic revision, three new genera (Hydropunctaria, Parabagliettoa, Wahlenbergiella) and eleven new combinations are proposed here. A summary of the current taxonomic and morphological circumscription of all genera investigated so far is also presented. Several monophyletic groups are identified for which further taxonomical changes will be required, but for which taxon and gene sampling is presently viewed as insufficient. Clear morphological synapomorphies were found to be rare for newly delimited genera. In some cases (reduced morphology or plesiomorphism), even the combinations of slightly homoplasious phenotypic characters do not allow a clear morphological generic circumscription. Molecular features are envisioned as characters for delimiting these taxa.

“…All parts of the island were studied. Some collections have previously been published in connection with a revision of Catapyrenium (Breuss & Hansen 1988). Additional information about the lichen flora of NW Greenland has previously been given by the author in the following publications: Hansen 1980, 1983, 1989, 2002, Hansen & Obermayer 1999, Hansen & al.…”

“…The type of distribution toward oceanity or continentality was estimated for all lichens by all available information about their total distribution in Greenland including monographs such as kärneFelt (1979), MoBerg & Hansen (1986), Hansen et al (1987) and Breuss & Hansen (1988). The maps and description of Greenland vegetation belts follow BöcHer et al (1968( ), tHoMson (1984 and Jensen (1999).…”

Hansen E.S., 2013: Lichens from three localities in Central West Greenland with notes on their climatic preferences [Trijų centrinės vakarų Grenlandijos vietovių kerpės ir pastabos apie jų klimatines preferencijas]. -Bot. Lith., 19(1): 28-36.A total of 165 lichen taxa collected from three localities in Central West Greenland in summer 2012 were reported and categorized toward their climatic preferences. Specimens of 68 lichen taxa were collected in Ilimanaq/Claushavn, 62 specimens -in Oqaatsut/Rodebay and 159 -in Ilulissat/Jakobshavn. Thirty four lichen taxa were recorded for the first time from Ilulissat, while all recorded lichens from Ilimanaq and Oqaatsut are new to those localities. More than 70% of the 165 lichens are more or less equally distributed in continental and oceanic areas of Greenland. About 20% of the lichens occur most frequently in oceanic areas and more rarely in continental areas, while a little more than 7% of the lichens occur frequently in continental areas and more rarely in oceanic areas. Two lichens are distinctly oceanic and one is distinctly continental. The climate of the three localities is low arctic, continental. As regards the distribution of the lichens, the results are in good accordance with those obtained from similar investigations in more southern areas of West Greenland.
