Mosses of the Mediterranean, an annotated checklist - Optima-bot.org

218 R.M. Ros, V. Mazimpaka et al.Annotations[1] Acaulon longifolium was described by Herrnstadt & Heyn (1999) from Israel, and thatis the only country where it is known.[2] Olsson et al. (2011) established that the genus Neckera as traditionally understood wasparaphyletic, and proposed its subdivision into four separate genera: Neckera s.s.,containing the generic type Neckera pennata; Forsstroemia Lindb., which is absent inEurope and the Mediterranean area; Alleniella S. Olsson, Enroth & D. Quandt(including the European A. besseri and A. complanata), and Exsertotheca S. Olsson,Enroth & D. Quandt (including E. crispa and E. intermedia). Draper et al. (2011)included the recently described Neckera baetica Guerra in the genus Exsertotheca asE. baetica (Guerra) Draper, González-Mancebo, O.Werner, J. Patiño & Ros, anddemonstrated that the European species Neckera cephalonica and N. pumila should beincluded in Neckera s.s. The only species for which the generic placement remainsuntested by molecular data is Neckera oligocarpa (known in the study area only fromItaly) but Draper et al. (2011) suggested its possible inclusion in Neckera s.s., due to itsmorphological proximity to N. pennata.[3] The combination Anomobryum bavaricum was published by Holyoak & Köckinger(2010). According to these authors this species has often been confused withA. concinnatum.[4] Atrichum androgynum was reported as new to the European flora (including mainlandPortugal, Madeira and the Azores) by Sérgio et al. (2010).[5] Barbula semilimbata Dixon & Luisier, previously considered a Madeiran endemic, hasbeen synonymised with Ceratodon purpureus by Sérgio et al. (2006).Ceratodon purpureus var. rotundifolius Berggr. has been reported from Italy and thisname is considered at present a synonym of Ceratodon heterophyllus Kindb. Accordingto Hill et al. (2006) European records of C. heterophyllus are based on plants that lackcapsules and according to the account of Burley & Pritchard (1990) are not reliable.Consequently Ceratodon heterophyllus should also be excluded from theMediterranean area.[6] Barbula arcuata was reported from Egypt by Shabbara (2006). This is the onlyMediterranean report of this species widely distributed in Central and South Americaas well as in Asia, but not known from any other adjacent territory in Europe andAfrica. A similar case is that of the American and Asian taxon Didymodon tectorum.It was reported from Egypt by Imam & Ghabbour (1972), and is the only report fromthe Mediterranean. Both reports require verification.[7] Brachymenium exile is a widely distributed species, but is absent in the European partof the Mediterranean basin.[8] Brachythecium ehrenbergii Lorenz was described from Syria, but its identity has notbeen revised since.[9] Düll (1984, 1985) reported several species from Northern Africa without any indicationof individual countries or supporting data concerning localities and, as previouslystated by Ros et al. (1999), no further report from these countries has been found in theliterature consulted for this paper. Therefore, these species – Brachytheciummildeanum, Didymodon ferrugineus, D. sinuosus, Grimmia donniana, Hennediellaheimii, Leucobryum glaucum, Neckera pennata and Zygodon conoideus – should beexcluded from the flora of the African part of the Mediterranean.[10] The generic classification proposed by Holyoak & Pedersen (2007) for the Bryaceaehas been followed in this checklist. These authors have taxonomically resolved somecomplexes on the basis of available molecular data, but several species are stillunresolved and are therefore retained in Bryum s. l. However, some exceptions havebeen made: Bryum mildeanum has been included in the genus Imbribryum based on
