In recent years, the number of studies concerning population genetics and phylogenetics in mosses using molecular markers has remarkably grown. This review summarizes the main features of the most used molecular techniques based on PCR and their application in bryology, with particular attention to mosses. This work also provides a bibliographic guide to 108 molecular studies focused on mosses to assist in choosing the most suitable markers according to the main aims of a specific research.

An account of the Lejeunea species of Thailand with their distributional ranges in Thailand and worldwide is presented. Seven species are newly recorded to Thailand: Lejeunea cocoes Mitt., L. lumbricoides (Nees) Nees, L. micholitzii Mizut., L. parva (S.Hatt.) Mizut., L. patersonii (Steph.) Steph., L. tamaspocsii G.E.Lee and L. umbilicata (Nees) Nees. Illustrations of the newly recorded species and a map of the provinces of Thailand with numbers of Lejeunea species recorded are also provided.

A revised and updated checklist of the bryophytes of the Sierra Nevada Mountains (Southern Spain) is presented, based on a compilation of bibliographic records, a revision of herbarium specimens and extensive field work. The Sierra Nevada, which occupies around 2000 km², is the southernmost mountain range in continental Europe. It has a wide diversity of habitats due to its range of altitude, a variable landscape, geological substrata and soil, hydrological resources, climate, etc. It is therefore of great botanical interest within the Mediterranean Region. A total of 395 taxa are currently accepted in the area: 2 Anthocerophyta, 69 Marchantiophyta and 324 Bryophyta (excluding infraspecific taxa, there are 2 species of hornworts, 68 species of liverworts and 309 species of mosses). The total number of species represents 21.8% of the European, 24.2% of the Mediterranean and 35.3% of the Iberian bryoflora. In addition, a total of 35 taxa are considered to be doubtfully present in the area, and 34 are excluded from the final list. Among the accepted species, three are included in the category of Critically Endangered in the Spanish Red List of threatened bryophytes, one is Endangered, 19 are Vulnerable, and one is considered Extinct in the studied area. The main threats for bryophytes in the area are analyzed. The original material of Bryum perremotifolium Thér., from the Sierra Nevada, is lectotypified and reidentified as Bryum schleicheri.

Cephaloziella uncinata R.M. Schust. (Cephaloziellaceae, Marchantiophyta) has been observed in a peaty forest of a former loop of the Seine River (Seine-Maritime, Haute-Normandie). The criteria for a correct identification of this leafy liverwort, which is new to France, are discussed and compared synthetically to those of some close taxa. The ecology of its habitat and its worldwide distribution are given. The conservation issues of the species are discussed

The moss species Myurella sibirica (Müll. Hal.) Reimers is reported for the first time from Serbia and Montenegro. The new records significantly extend the known European range of this Europe-wide endangered species into the southeast. The species was found in limestone rock crevices in mountain to high mountain areas.

New locality records of three species of Barbula are added to the Chinese moss flora. Barbula hiroshii K. Saito is newly reported to China. Additional localities are reported for Barbula amplexifolia (Mitt.) A. Jaeg. and Barbula convoluta Hedw. Brief morphological description, range extension, digital photographs of the three species and a new key to Chinese species of Barbula are provided.
