Riccia melitensis was considered to be an andemic species of the Maltese Archipelago and has never been relocated in the field since its discovery in 1913. The type specimen of Riccia melitensis Mass. has been examined and its taxonomic morphological characters re-evaluated. As a result, R. melitensis is considered to be a synonym of R. ciliifera L...

The male of the rare South African bethylid species, Tuberepyris codex Azevedo & Mugrabi, is discovered, described and illustrated. The conspecific gender association is established based on the high level of morphological congruence between the newly collected male and the known female specimen, facilitated by the unusually low level of sexual dim...

Hornworts Sterile thalli of hornworts have often been seen, only once with immature sporophytes at Loc. 28, 38614, as "Anthocerotae" (no spores seen, cultivation at home failed reMArks Known from atlantic and subatlantic Europe, but mainly mediterranean region, north Africa, Israel, Turkey and Bulgaria (detailed distribution in Jovet-Ast 1986); not rare in Sicily (Dia et al. 1985), but new to the Maltese Islands. reMArks Riccia melitensis, known only from the type locality on Gozo, has recently been synonymized under R. ciliifera (Hugonnot 2015). Surprisingly, R. melitensis/ciliifera has never been found again on the Maltese Islands though it seems to belong there together with Riccia sorocarpa to the most frequent member of this genus, sometimes occurring in large mats of up to more than 1 m 2 . ...
During a recent visit of the Maltese Islands Malta and Gozo in January 2018, some 200 collections of bryophytes have been done representing one species of hornworts, 14 species of liverworts and 49 species of mosses, among these six first records (Riccia ciliata Hoffm., Targionia lorbeeriana Müll.Frib., Amblystegium serpens (Hedw.) Schimp., Cheilothela chloropus (Brid.) K.Saito, Ephemerum recurvifolium (Dicks.) Boulay, and Tortula cuneifolia (Dicks.) Turner). Riccia ciliifera Link ex Lindenb., Riccia crozalsii
Levier and Acaulon muticum (Hedw.) Müll.Hal. have been redetected after more than 100 years, and the occurrence of three very recently reported species (Cephaloziella baumgartneri Schiffn., Astomum crispum (Hedw.) Hampe and Tortula vahliana (Schultz) Mont.) has been confirmed.
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.
