One of these species, Riella helicophylla is the type of the genus. Apart from being of conservation concern, it has been used as a model organism for cytological and physiological processes. The species was described from Algeria in the mid‐nineteenth century and was not found elsewhere for almost a century, when it was discovered in central Spain. Nonetheless, those new populations were considered morphologically different and served to describe a new variety (var. macrocarpa), and a form (f. latealata) of the latter. The number of population records increased considerably in the following decades, especially in the late twentieth century; at the same time, it was discovered in several countries throughout the Mediterranean basin. Those reports, however, did not account for its infraspecific distinction. As part of a broader study of the genus, in this work, we have revisited the taxonomy of R. helicophylla based on an integrative approach considering morphological and molecular DNA sequence data. Our broadly sampled study revealed that R. helicophylla includes two morphotypes corresponding with the previously recognized varieties of this species. These varieties differ consistently in a number of morphological gametophytic and spore traits. Riella helicophylla was resolved as paraphyletic in phylogenies based on nuclear and plastid DNA sequences. The accessions clustered in two monophyletic clades in concert with morphology, supporting their recognition at the species level. Accordingly, a new combination is proposed, R. macrocarpa, which includes the neglected R. helicophylla var. macrocarpa and R. helicophylla var. macrocarpa f. latealata. Lectotypes are designated for the two latter taxa and for R. helicophylla. The two species are fully described and illustrated, and an updated identification key of the Mediterranean species is included. Updated information on the conservation status of both species is provided.

Although bryophytes could be used in medicine, their chemistry is not very well known and the problem remains to obtain enough quantity of same species for analysis. In vitro cultivation of bryophytes is the most appropriate way for large biomass production and isolate of numerous useful compounds showing some interesting biologic activities. This technique is also useful in developmental, cellular, molecular, biochemical, and eco-physiologic studies.

A total of 143 bryophyte taxa (17 hepatics and 126 mosses) were recorded within the metropolitan area of Cologne. Three species were newly recorded for North Rhine‐Westphalia: Hannediella heimii, Schistidium helveticum and Tortula schimperi. Thirteen species red‐listed in NRW were recorded, among them hardly endangered: Bryum intermedium and Syntrichia laevipila and extinction endangered: Syntrichia papillosa. The ...

New records of Mediterranean-Atlantic mosses in the flora of Serbia. — Herzogia 29: 185–189. During extensive field research on cryptogams of the lower Ibar Valley in Central—SW Serbia three moss species were recorded new to the bryophyte flora of Serbia. These are Dialytrichia mucronata, Grimmia lisae and Gymnostomum viridulum.
