Tayloria rudolphiana (Garov.) Bruch et Schimp. was grown in axenic culture, from spores and gametophyte fragments to study its development patterns for the first time. It was grown for 16 months on Parker's growth media under a 14h light/16°C-10h dark/14°C cycle with daylight fluorescent lighting. The expansion of protonemata filaments and branch formation in T. rudolphiana followed the typical tip growth pattern seen in mosses. All types of protonemata cells were observed (chloronemata, caulonemata and rhizoids) in specific developmental sequences, depending on their origin. Protonemata (caulonema) derived brood cells were observed for the first time in T. rudolphiana. Brood cells formed at the ends of the caulonemal filaments as chains of short, relatively thick-walled, spherical cells, containing abundant chloroplasts and some lipid droplets. Brood cells developed after 4 months in culture on colonies initiated from spores.

Bucklandiella angustissima Bednarek-Ochyra et Ochyra is described as a new species. It is known in Australasia from the southern cool-temperate zone of the South Island of New Zealand and its offshore islands including the Auckland and Campbell Islands, as well as subantarctic Macquarie Island, and in South America from the northern Andes of Ecuador. The new species belongs to Bucklandiella Roiv. sect. Emersae (Bednarek-Ochyra) Bednarek-Ochyra et Ochyra and is allied to Australasian B. emersa (Müll. Hal.) Bednarek-Ochyra et Ochyra. It is a saxicole readily distinguished from all its congeners in having very small, subglobose to ovoid or obloid capsules, 0.5–0.8 mm long, on fairly stout and very short setae, only 0.8–1.2 mm. These are the smallest capsules and the shortest setae in the large genus Bucklandiella. Additionally, the species has very short peristome teeth, 200–220 µm long, and a very narrow costa, 40–60 µm wide, with only two enlarged adaxial epidermal cells throughout its entire length. The taxonomic status of Racomitrium crispipilum (Taylor) A. Jaeger var. brevifolium Thér., which is known only in sterile condition from a single altimontane site in Ecuador, is briefly assessed and this variety is considered to be identical to Bucklandiella angustissima. Five new combinations are made: Bucklandiella subsect. Andicola (Bednarek-Ochyra) Bednarek-Ochyra et Ochyra, B. subsect. Depressae (Bednarek-Ochyra) Bednarek-Ochyra et Ochyra, B. depressa (Lesq.) Bednarek-Ochyra et Ochyra, B. dichelymoides (Herzog) Bednarek-Ochyra et Ochyra, and B. subcrispipila (Müll. Hal.) Bednarek-Ochyra et Ochyra. The latter name is neotypified.

Campylopus joshii Broth. ex Pichonet et Bardat is described as a new species from Uganda and the Democratic Republic of Congo. The type specimen was initially named Dicranum joshii Broth, ex Thér. and Dicranum joshii var. latifolium Thér. et Naveau but these names have never been validly published. The new species resembles the groups of Campylopus species with ventral hyalocysts and a ridged costa on the dorsal side but differs by the incomplete band of ventral stereids and single-celled dorsal lamellae.

We provide first Canary Islands reports of Diphyscium foliosum (Hedw.) D. Mohr, Entosthodon longicolle (Trab.) Ros et M.J. Cano, Tortella alpicola Dixon and T. bambergeri (Schimp.) Broth., being the last three also new to Macaronesia. First individual island reports are given for Acaulon mediterraneum Limpr. (Gran Canaria, Tenerife), and Tortella limbata (Schiffn.) Geh. et Herzog (Tenerife). Brief taxonomic notes are added. Entosthodon fascicularis (Hedw.) Müll. Hal. is removed from the list of Fuerteventura and Tortella fragilis (Hook. Wilson) Limpr. from the list of the Canary Islands.

The major peatlands of Aubrac plateau have been bryofloristicaly investigated. A list of 141 taxa is provided, among which 32 taxa are considered of high conservation value. Emphasis is put on the most remarkable sites from the points of view of richness in overall bryophyte flora and in taxa of high conservation value.

Based on a floristic study of bryophytes from southern Ecuador, we report eight species new to the country (Mastigolejeunea auriculata, Metzgeria cylindra, M. saccata, Plagiochila martiana, Porella leiboldii, Riccia crassifrons, Sematophyllum steyermarkii, Zoopsidella caledonica), nine new to southern Ecuador and several new to the provinces of El Oro, Loja or Zamora Chinchipe. Metzgeria saccata and Zoopsidella caledonica are recorded for the first time in the New World. Fissidens hydropogon and Lepidopilum caviusculum, two rare rheophytic mosses collected by Richard Spruce in the province of Pastaza (río Bombanasa) in 1857 and never seen again since, are newly reported from the province of Zamora Chinchipe (río Nangaritza).

En un estudio floristico de briófitas del sur de Ecuador se registraron ocho especies nuevas para Ecuador (Mastigolejeunea auriculata, Metzgeria cylindra, M. saccata, Plagiochila martiana, Porella leiboldii, Riccia crassifrons, Sematophyllum steyermarkii, Zoopsidella caledonica), nueve nuevas para el sur del país y varias especies nuevas para las provincias de El Oro, Loja o Zamora Chinchipe. Metzgeria saccata y Zoopsidella caledonica son registradas por primera vez para el Nuevo Mundo. Fissidens hydropogon y Lepidopilum caviusculum, dos musgos semi-acuáticos raros colectados por Richard Spruce en 1857 en la provincia de Pastaza (río Bombanasa) y que no se habían encontrado desde entonces, son registrados nuevamente de la provincia de Zamora Chinchipe (río Nangaritza).

Some interesting mosses discovered at the Laga Mountains in the central Apennines are reported. Myurella sibirica, a very rare moss in Europe, is rediscovered in Italy after more than one century. Dicranella cerviculata and Dicranum flexicaule, only known from northern Italy, are reported for the first time from Central Italy. Finally, Dicranum polysetum and Pseudoleskea patens are reported as new for the Abruzzo region. Ecological and chorological remarks are given for each species.

The thalloid liverwort Riccia subbifurca Warnst, ex Croz. is reported for the first time from Turkey, bringing the total number of Riccia taxa known from Turkey to twenty two. The new hepatic was collected in Bafa Lake Natural Park, from western Turkey.
