Bryophyte Diversity and Evolution

***Schistidium foraminis-martini* sp. nov. (Grimmiaceae), a high mountain calcicole from the European Alps molecularly related to *S. agassizii***

2021-07-13T13:27:27+12:00

Schistidium foraminis-martini is described as a new species from the Austrian and Swiss Alps. The taxon is characterized by a warm brown coloration, ovate, concave and muticous leaves with rounded apices, ellipsoid capsules, constricted at mouth, the presence of stomata and a reduced, truncate peristome. Based on sequences of the ITS region the new species is phylogenetically rather isolated, exhibiting the closest relationship to S. agassizii which shares the muticous leaves but differs in having narrowly lingulate-lanceolate, almost flat leaves, cyathiform capsules and a perfect peristome. Schistidium foraminis-martini grows on moist calcareous rocks in the alpine and nival belt.

**Two new species of Ceratolejeunea (Lejeuneaceae) and five noteworthy records for Brazil**

The Brazilian state of Amazonas harbors an exceptionally high number of bryophyte species for its size, yet many taxa remain to be discovered. Herein, we continue by further describing and illustrating two new species, as well as by providing evidence for substantial geographical extensions of another five taxa. Two new species, Ceratolejeunea ocirii and Ceratolejeunea semicornua are herein described. Cololejeunea appressa is newly recorded for Brazil, and Cheilolejeunea savannae, Cololejeunea clavatopapillata, Prionolejeunea galliotii and Plagiochila eggersii are new records for the state of Amazonas, Brazil.

Diversity of mosses in some underexplored regions of Manipur, Northeast India

2021-12-23T11:41:09+13:00

The present paper deals with the investigation of moss taxa of some underexplored regions of Manipur, Northeast India. During the assessment of moss diversity in various localities of Manipur a total 126 species of mosses belonging to 84 genera in 34 families have been investigated and enumerated. Ten species, namely Amblystegium serpens,Entodontopsis leucostega, Entodontopsis tavoyensis, Homalia trichomanoides, Lindbergia duthiei, Philonotis mollis, Philonotis thwaitesii, Taxiphyllum giraldii,Tortella humilis and Thuidium sparsifolium are new additions to Eastern Himalaya, while 92 species of mosses have been reported for the first time from Manipur. Ten Indian endemic taxa have also been identified from the explored sites. The majority of the taxa were recorded from epiphytic habitats.

**Phylogenetic study of the genus Pohlia (Mielichhoferiaceae, Bryophyta) based on chloroplast DNA sequences**

The phylogenetic circumscription and taxonomic status of the genus Pohlia in the Mniaceae sensu lato was investigated based on chloroplast DNA sequences (rbcL, rps4, and trnL-F), with a focus on species occurring in Japan. The maximum likelihood and Bayesian inference analyses of sequences obtained from 34 species of Mniaceae s.l., including 13 Pohlia species, suggested that the genus Pohlia and the family Mielichhoferiaceae are not monophyletic in their present circumscription, but confirmed that the family Mniaceae is monophyletic in its traditional sense. These results are congruent with previous molecular phylogenetic studies. Three distinct clades were recognized in the Mielichhoferiaceae, almost corresponding to three sections of Pohlia (Pohlia, Cacodon and Apalodictyon). One of them branched off first within the Mniaceae s.l., and the other two were sister to the remainder of the Mniaceae s.l. The single included Schizymenium formed a monophyletic group with Pohlia sect. Pohlia and Epipterygium with Pohlia sect. Apalodictyon, confirming the results of previous studies. The results indicate that the taxonomic status of the genus Pohlia and family Mielichhoferiaceae are in need of revision. Phylogenetic analyses nested the accessions of P. camptotrachela within P. annotina and P. flexuosa clades, highlighting the need for taxonomic revision of Japanese propaguliferous Pohlia species.
