Calymperes boulayi Besch. is reported from Hahajima Island, the Ogasawara (Bonin) Islands, Tokyo, Japan. This report is a new addition to the Japanese bryophyte flora. The locality of Hahajima Island is considered to be the northern limit of the species distribution. Based on the Japanese materials, a description, figures and notes of this species are given.

  Chenia leptophylla (Müll.Hal.) R.H.Zander (Pottiaceae), a cosmopolitan moss species is reported here as a new genus and species record for Thailand. It occurs on soils near the Bhu Ping Palace, Doi Suthep-Pui National Park, Chiang Mai Province, Northern Thailand. A brief description and photographs are provided.

  The recent collections of Drepanolejeunea laciniata Qiong He & R.L.Zhu from the type locality, Doi Inthanon National Park, Chom Thong District, Chiang Mai Province, Thailand, revealed male plants and asexual reproductive organs for the first time. The species is described and illustrated in detail, and geographical distribution are briefly discussed. A review of androecia and asexual reproduction in all the Thai Drepanolejeunea species is included.

  We investigate two species of Cyathodium Kunze ex Lehm. (Cyathodiaceae) found in Malaysia, namely C. cavernarum Kunze ex Lehm. and C. foetidissimum Schiffn. We document the discovery of C. cavernarum in five new localities across Peninsular Malaysia, all within limestone caves, along with a distribution map. Additionally, we provide a key to the species of complex thalloid liverworts (Marchantiopsida) in Malaysia. The discussion includes the distribution and habitat of each species and the morphological variations among them and their related species.

  The authors collected more than 1,000 bryophyte specimens for the project: The Role of Nature for Human Well-being in the Kilimanjaro Social-Ecological System (Kili-SES), all of which were identified by T. Pócs. Thirty-five taxa are new to the Kilimanjaro area, and nine of these are even new to the bryoflora of Tanzania: Bazzania decrescens subsp. molleri (Steph.) E.W.Jones, Bryum rhypariocaulon Müll.Hal., Fissidens angustifolius Sull., F. weirii Mitt., Grimmia trichophylla Grev., Leucoloma schelpei P.de la Varde, Plaubelia involuta (Magill) R.H.Zander, Tortula atrovirens (Sm.) Lindb. and Trachypodopsis laxoalaris Broth.

  Eleven Mio–Pliocene bryophyte fossils found in Japan were examined. Nine of them had been previously reported as Hepaticites sp. (Marchantiophyta) or Muscites sp. (Bryophyta), and the other two were examined in this study for the first time. After detailed morphological observations of the nine specimens, a species of the lycophyte spikemoss genus Selaginella (Tracheophyta), a species of Lophocoleaceae (Marchantiophyta), and a species of Hypnales (Bryophyta) were identified. A species of Mniaceae (Bryophyta) and a species of Jungermanniales (Marchantiophyta) have been reported on the basis of these two additional specimens.
