On the anatomy of the costa in Fissidens

Based on a study of ca. 120 Fissidens species covering all sections and subgenera, three types of costae are recognized. One type is characteristic of sect. Amblyothallia and of F. asplenioides, F. fasciculatus and F. plumosus (the fasciculatus group); the second of subg. Serridium, subg. Fissidens sect. Crispidium andF. Grandifrons (subg. Pachyfissidens) and the third type of subg. Fissidens sect. Fissidens, sect. Aloma, sect. Crenularia, sect. Semilimbidium, sect. Pycnothallia, and sect. Areofissidens, subg. Octodiceras, and subg. Sarawakia

An annotated checklist of bryophytes of Europe, Macaronesia and Cyprus

Introduction. Following on from work on the European bryophyte Red List, the taxonomically and nomenclaturally updated spreadsheets used for that project have been expanded into a new checklist for the bryophytes of Europe. Methods. A steering group of ten European bryologists was convened, and over the course of a year, the spreadsheets were compared with previous European checklists, and all changes noted. Recent literature was searched extensively. A taxonomic system was agreed, and the advice and expertise of many European bryologists sought. Key results. A new European checklist of bryophytes, comprising hornworts, liverworts and mosses, is presented. Fifteen new combinations are proposed. Conclusions. This checklist provides a snapshot of the current European bryophyte flora in 2019. It will already be out-of-date on publication, and further research, particularly molecular work, can be expected to result in many more changes over the next few years.Peer reviewe

An annotated checklist of the mosses of Europe and Macaronesia

The moss flora of Europe and Macaronesia comprises 278 genera, 1292 species, 46 subspecies and 118 varieties. Of the total 1292 species, 53 are confined to Macaronesia and 21 are thought to be non-native. The checklist was derived from those for the various component countries and regions. It is based on results published up to the end of 2005. Subspecies and varieties are included; hybrids are omitted. The taxonomic hierarchy is based on one published by Goffinet & Buck in 2004. While it has been strongly influenced by results of modern molecular methods, there are still many remaining uncertainties, even at family level. Because of these uncertainties, taxonomic innovation has generally been avoided. There are four new combinations and one change of status
