“…However, the new revision of Trismegistia (Akiyama 2010) has distinguished the two names as distinct taxa. The identity of some earlier reported specimens of T. rigida from Vietnam have been verified by Akiyama (2010) and treated under T. calderensis var. rigida (Reinwardt & Hornschuch 1829: 731) H. Akiyama (2010: 11), a name not validly published, and should be corrected to T. calderensis var.…”

This study of recent collections of mosses in Vietnam and Laos yield 10 new records for Indochina, 15 new records for Vietnam, 2 new records for Laos, and 5 other noteworthy records, including significant range extension and validation of doubtful records. Acroporium rufum is an erroneous record and should be removed from the Vietnamese flora. A new combination Distichophyllum cuspidatum var. subcuspidatum is proposed, whereas Trichosteleum montanum is considered a new synonym of Papillidiopsis ramulina. The occurrence of Thuidium pristocalyx var. orientale, a name overlooked in previous moss checklists of Vietnam, is here supported with an authentic specimen. Trismegistia lancifolia and T. rigida (= T. calderensis var. convoluta), which have been recently resurrected from synonymy accepted in previous checklists, are both confirmed to occur in Vietnam from our collections.

“…The latter species may have Asian ancestors and has possibly colonised the Neotropics in rather recent times (Akiyama et al . 2015). It is a montane rather than a lowland species and occurs from Mexico southwards to Bolivia, in Brazil and in the Caribbean (Buck 1998).…”

A Caribbean epiphyte community preserved in Miocene Dominican amber

Fossil tree resins preserve a wide range of animals, plants, fungi and microorganisms in microscopic fidelity. Fossil organisms preserved in an individual piece of amber lived at the same time in earth history and mostly even in the same habitat, but they were not necessarily parts of the same interacting community. Here, we report an in situ preserved corticolous community from a piece of Miocene Dominican amber which is composed of a lichen, a moss, and three species of leafy liverworts. The lichen is assigned to the extant genus Phyllopsora (Parmeliaceae, Lecanoromycetes) and described as P. magna Kaasalainen, with open areas, and were rich in epiphytes (Grimaldi, 1996). Based on its animal and plant inclusions, the Dominican amber forest has been characterized as a moist tropical forest, which was not remarkably different from the modern Neotropical lowland rainforest (Grimaldi 1996; Poinar & Poinar 1999). Three species of lichens, 22 species of liverworts, and 29 species of mosses have so far been described from Dominican amber, of which the liverworts clearly represent extinct taxa (Poinar et al. 2000;Rikkinen & Poinar 2008; Heinrichs et al. 2015a). Also the fossil lichens have been described as representatives of extinct species, however, the absence of several important chemical and apothecial characters hinders a reliable differentiation between the fossil and morphologically similar extant species (Poinar et al. 2000;Rikkinen & Poinar 2008 DNA sequence variation of extant species provides certain likelihood for a species age that is in accordance with the age of the amber (Heinrichs et al. 2013b, Villarreal & Renner 2014 Heinrichs et al. 2015b;Váňa et al. 2015).Here, we present a piece of Dominican amber that provides a window on a Miocene Caribbean epiphyte community. The virtually in situ preserved cryptogamic community includes a new species of the extant lichen genus Phyllopsora, a moss that is similar but clearly distinguished from the modern genus Aptychella and therefore assigned to the new fossil genus Aptychellites, as well as three extinct species of the extant leafy liverwort genera Cheilolejeunea, Lejeunea, and Radula. The members of this community are distinct from extant Caribbean species, further substantiating the notion of a stasis in morphotype diversity but a certain turnover of species in the Caribbean since the early Miocene as recently suggested by Schneider et al. (2015). It is also in line with the hypothesis of Poinar and Poinar (1999) that many of the plants and animals preserved in the Miocene Dominican amber do not have immediate extant descendants. Material & MethodsThe fossilized epiphytes are preserved in a ca 3 cm x 2 cm x 0.8 cm sized piece of Dominican amber which is housed in the amber collection of the American Museum of Natural History in New York (AMNH DR-15-3). The amber specimen originated from the amber mines in the Cordillera of the Dominican Republic.The mines in the Northern, Eastern and Western parts of the Dominican Republic yield ambers with an...

“…Although the monophyly criterion is satisfied based on single‐gene phylogenies with limited taxon sampling, and morphological synapomorphy is also not observed, the Pylaisiadelphaceae have been widely accepted (e.g., Ramsay, 2012; Câmara & Shaw, 2013; Akiyama et al, 2015). Though the using of three genes ( rps4 , trnL , and nad5 ) for the Shimodaira–Hasegawa (SH) test could not reject the monophyly of the Pylaisiadelphaceae (Carvalho‐Silva et al, 2017), the family was resolved as paraphyletic in recent phylogenetic analyses (Cox et al, 2010; Akiyama et al, 2011; Carvalho‐Silva et al, 2014, 2017).…”

The Sematophyllaceae s.l. (Sematophyllaceae s.str. + Pylaisiadelphaceae) is one of the most diversified families of pleurocarpous mosses, distributed worldwide. The familial definition and subfamilial delimitation of the family have been controversial since their inception. Phylogenetic analyses were carried out using Bayesian inference, maximum likelihood, and maximum parsimony analyses. Our molecular phylogenetic analysis using five molecular markers (nad5, rbcL, rps4, trnL‐F, and 26S) from mitochondrial, chloroplast, and nuclear genomes revealed the paraphyly of the Pylaisiadelphaceae and the monophyly of Sematophyllaceae s.l. Based on the molecular and morphological evidence, the Sematophyllaceae s.l. were further divided into six subfamilies, Taxithelioideae, Isopterygoideae, Pylaisiadelphoideae, Aptychelloideae, Platygyrioideae, and Sematophylloideae. The Taxithelioideae is established to accommodate Taxithelium, Taxitheliella, and Vernieri, the Isopterygoideae is established to accommodate Isopterygium and Yakushimabryum, the Pylaisiadelphoideae is newly circumscribed to accommodate Brotherella, Pylaisiadelpha, and Orientobryum, the Aptychelloideae is established to accommodate Aptychella, the Platygyrioideae is temporarily established to accommodate Clastobryella, Clastobryum, Gammiella, Platygyrium, and Trachyphyllum, the Sematophylloideae is resurrected to accommodate the Sematophyllaceae s.str., and Isocladiella, Isocladiellopsis, Mastopoma, Heterophyllium, Pseudotrismegistia, Trismegistia, and Wijkia are transferred to the subfamily. A new classification for the Sematophyllaceae s.l. is then proposed.
