Based on studies of the nuclear marker ITS, the plastid ones atpB-rbcL and rpl16, and morphology, five species are recognizable within Scandinavian Plagiopus oederianus. Four of these species are cryptic, whereas the fifth one, Plagiopus alpinus (Schwaegr.) Hedenäs, comb. et stat nov., can be distinguished from the other ones by morphology. Plagiopus alpinus is smaller than the four cryptic species within P. oederianus and has smaller spore capsules, smaller exothecial cells, shorter leaves and shorter lamina cells in the middle and base of the leaves. In Scandinavia, P. alpinus occurs in the mountain range, whereas the cryptic species within P. oederianus occur both in the mountains and in the lowlands. Outside Scandinavia, P. alpinus is known from the European Alps but it seems likely that it is widespread in mountains and northern regions of the northern hemisphere. The cryptic species within P. oederianus differ in several molecular bases.

As a result of bryological collecting trips in the Maçka District (Trabzon Province) in Turkey, a total number of 235 bryophytes belonging to 108 genera (17 liverworts and 91 mosses) were determined from 20 different localities. Of these, 26 taxa belong to liverworts and 209 taxa belong to mosses.

The molecular variation (atpB–rbcL spacer, rpl16 G2 intron, trnGUCC G2 intron) among 50 Scandinavian specimens of Meesia uliginosa s.l. was analysed in the context of three other Meesia species, with Paludella squarrosa as outgroup. The molecular variation within M. uliginosa correlates with morphology, and shows that three species exist: M. uliginosa Hedw., M. minor Brid. and M. minutissima Hedenäs sp. nov. Whereas M. uliginosa s.str. is widespread, in Scandinavia the other two species are restricted to the mountains. The three species differ in quantitative features, such as, plant size, leaf size, costa width, leaf apex shape, seta length and spore capsule size. Because the species overlap in several of these features, a combination of seta length and the ornamentation of the exostome outside are the safest characters for identification. Leaf apex shape, small spore capsules in M. minutissima and large spores in M. minor serve as additional identification help. Meesia minutissima is presently only known from Scandinavia. The other two species are more widespread, although further investigations are required to find out their exact distributions.

Four species of lichen-forming fungi (Calicium pinastri, Chaenotheca laevigata, Lecania croatica and Pycnora praestabilis) and two lichenicolous fungi (Arthrorhaphis aeruginosa and Chaenothecopsis epithallina) are reported as new for Latvia. The first comprehensive list of lichenicolous fungi in Latvia is also presented, including their hosts and distribution in Latvia (northern Europe).

Scopelophila cataractae is a rare species that grows in environments with high concentration of copper. We analyzed the relationship between plant growth and copper ion concentration in the rainwater in a field study and the relationship between photosynthetic activity and copper ion concentration in a laboratory. We surveyed six sites with S. cataractae; these sites had rainwater copper ion concentrations ranging from 16.8 to 29.2 ppm. We found that the growth area, gametophore size, and leaf size of S. cataractae decreased as copper ion concentration increased. We observed reduced photosynthetic activity at copper ion concentrations of 20.0 ppm or higher. We discovered that the growth of S. cataractae gametophores was adversely affected by copper ions at concentrations commonly observed under copper roofs. Thus, S. cataractae may inhabit areas with high concentrations of copper ion (∼30 ppm) partly because of a selective advantage when interspecific competition is high. We recommend that copper roofs should be renewed partly rather than all at once, as aged copper roofs create environments with copper ion concentrations suitable for S. cataractae.

The IUCN Red List is recognised as a robust system for assessing the risk of extinction to organisms, but there are difficulties in applying the criteria to bryophytes and other clonal and colonial organisms. Three critical terms are addressed – generation length, mature individual and severe fragmentation – and definitions given in order to facilitate the use of the IUCN Red List criteria for bryophytes. These recommendations provide a pragmatic and effective way of using the IUCN Red List process for bryophytes and may have a wider application to other clonal organisms.

Wiesnerella denudata (Mitt.) Steph., a complex thalloid liverwort in the family Wiesnerellaceae (Marchantiales), is reported as a new species to Peninsular India from the Anamudi Shola National park in the Western Ghats of Kerala. This species is easily confused with another thalloid liverwort, Dumortiera hirsuta (Sw.) Nees, due to similar morphological characters, especially size of thallus, colour and habit. Wiesnerella denudata is characterised by the presence of elevated air pores which can be seen with the help of a hand lens or even with naked eye, subsessile rotund male receptacle, raised female receptacle with deeply dissected carpocephalum and absence of pseudoperianth. A detailed account of the species along with photographs and SEM images of spores is provided here.

During field investigations of semi-natural habitats of the city of Podgorica and its vicinity, the aquatic moss, Fissidens fontanus was found in the rivers Sitnica and Cijevna. This is the first report of the species from Montenegro. The species grows together with Fissidens crassipes and Fontinalis antypiretica, which are common mosses in the Montenegrin rivers. At the Balkan Peninsula, Fissidens fontanus is also known from Bulgaria, Greece and Romania.
