New to Macaronesia are Aneura pseudopinguis, Didymodon brachyphyllus, Diplophyllum obtusifolium, Distichium capillaceum, and Schizymenium pontevedrense.First archipelago reports concern Brachythecium albicans (Canary Islands), Bryum dichotomum (Cape Verde), B. kunzei (Canary Islands), Homalothecium aureum (Cape Verde), Hydrogonium bolleanum (Madeira), Isopterygiopsis pulchella (Canary Islands), Pohlia cruda (Madeira), Pterygoneurum ovatum (Canary Islands), Schistidium flaccidum (Madeira), and Tortella fasciculata (Madeira). First single island reports are given for 42 species. Africa /Azores /Canary Islands /Cape Verde /Distribution data /Europe /Liverworts / Madeira /Mosses INTRODUCTION Macaronesia, in awide sense, consists of five archipelagos, including Cape Verde, Canary Islands, Selvagens, Madeira, and Azores. The islands have avolcanic origin and are situated in the Atlantic Ocean, offthe coasts of Southwestern Europe and Western Africa, between 15 and 30o N(Vanderpoorten et al.,2011). Macaronesia as awhole is recognizedasacentre of plant diversity (Myers et al.,2000). *Corresponding author: [email protected] doi/10.7872/cryb/v39.iss1.2018.61 62 G. M. Dirkse et al. The bryophyte flora of Macaronesia has been studied for about 200 years and has been summarizedtwo times (Geheeb &Herzog, 1910; Eggers, 1982). The bryophyte flora of separate Macaronesian archipelagos has been actualized recently as follows: Azores by Sjögren (2001) and Gabriel et al. (2010); Canary Islands by Dirkse et al. (1993), González-Mancebo et al. (2008), and Losada-Lima et al. (2010); Cape Verde by Frahm et al. (1996) and Patiño-Llorente &González- Mancebo (2005); and Madeira (Selvagens included) by Sérgio et al. (2006, 2008). Latest novelties have been added by González-Mancebo et al. (2009), Sérgio & González-Mancebo (2009), Ellis et al. (2010, 2011, 2012a, 2012b, 2013a, 2013b, 2015a, 2015b), Heinrichs et al. (2010), Dirkse &Losada-Lima(2011), Sérgio & Sim-Sim (2012), Draper et al. (2015), and Dirkse et al. (2016). The Mediterranean checklists of hepatics and anthocerotes (Ros et al.,2007) and mosses (Ros et al., 2013) also contain global data of separate Macaronesian archipelagos except for Cape Verde (and the Azores in the case of hepatics and anthocerotes). The growing interest of botanists in Macaronesia has lead to many new finds of bryophytes. Up till now,most finds have been kept in herbaria and remained un-published. The lack of up-to-date data on the regional distribution of bryophytes (Vanderpoorten et al.,2011) encouraged us to put our novelties together.Weaim at providing data on the distribution and taxonomy of noteworthy species, found during field work in Macaronesia. MATERIAL AND METHODS The novelties have accumulated from different projects, including: the Macaronesian and regional Canarian studies carried out by ALL, JMGM, JP,RHH, and ARR (Universidad de La Laguna); the on-going systematic investigation of the Canarian bryophyte flora by GMD (Natuurmuseum Nijmegen); collecting in Macaronesia for molecular studies by JMGM, AV, and JP (University of Liège, Universidade dos Açores); hollyday collecting in the Canary Islands and Madeira by AS and JAWN; and collections sent to us (GMD, ALL, AV)byothers. The collections have been made between 1988 and 2012. Of these, 60% was collected after 2004. The species accounts are presented in three categories: new to Macaronesia (5), new to an archipelago (10), new to one or more individual islands (42). Within these groups, the species are presented in alphabetical order.For each species the following information is given: archipelago, island, locality, Universal Transverse Mercator projection (UTM), altitude, habitat, collector(s), year of collecting, and herbarium voucher number.Distribution data are given as follows: for species new to Macaronesia at global scale; for those new to an archipelago at Macaronesian level; and for species new to individual islands, both at Macaronesian level and at island scale within the archipelago for which it is reported. In some cases taxonomical and/or morphological notes are added. UTM grid squares have been read from astandard12-channelGPS receiver. In the Canary Islands, the geographical positions, in particular altitudeswere taken from the 1:25.000MapaTopográfico Nacional de España(MTN25). Positions are given for the lower left-hand corner of 5×5kmUTM squares in wich collecting sites are located. The collections are kept in private or institutional herbaria as indicated in the text and are available for loan. References to institutional herbariaare abbreviated according to Index Herbariorum.Private herbaria are referred to by the family name of the owner. New bryophyte records from Macaronesia 63 Unless stated otherwise, nomenclature follows Ros et al. (2013) for Bryophyta and Ros et al. (2007) or Söderström et al. (2016) for Anthocerotophyta and Marchantiophyta. The names of vascular plants follow Borges et al. (2008) or Arechavaleta et al. (2010).

Aneura pseudopinguis was described from Brazil as Riccardia pseudopinguis (Herzog, 1942). Pócs placed it in Aneura (Gradstein et al.,1983). Although not accepted by Söderström et al. (2016), we follow here Sérgio &Garcia (2009) who amply discuss its taxonomy.Until recently it was considered atropical species, confined to tropical Africa and S. America (Meenks &Pócs, 1985; Wigginton, 2004). Sérgio &Garcia (2009) discovered it from Portugal and. Casas et al. (2009) found it in Spain, and later,Brugués et al. (2011) confirmed the record.
