    Didymodon edentulus (Bryophyta, Pottiaceae), a new Andean species from the Cordillera Occidental in Peru
    (Schweizerbart Science Publishers, 2015-05-01) Alonso García, Marta; Cano Bernabé, María Jesús; Guerra Montes, Juan; Jiménez Fernández, Juan Antonio; Biología Vegetal
    Didymodon edentulus J.A. Jiménez & M.J. Cano, is described and illustrated as a new Andean species from the Cordillera Occidental in north-central Peruvian departments of Ancash, La Libertad and Lima. It is characterized mainly by its appressed leaves when dry, plane margins above midleaf, smooth laminal cells, oblate and transversely thick-walled marginal basal cells, differentiated perichaetial leaves and gymnostomous capsules. Its distinction from, and relationships with some closely related species within the genus are discussed.

    Erythrophyllopsis perlaticosta M.J.Cano & J.A.Jiménez (Pottiaceae) a new species from the Peruvian Andes
    (Taylor and Francis Group, 2019-02-15) Alonso García, Marta; Cano Bernabé, María Jesús; Guerra Montes, Juan; Jiménez Fernández, Juan Antonio; Biología Vegetal
    Introduction. Over the last years we have been engaged in studies of the South American Pottiaceae. Among the bryophyte specimens collected by us in central and northern Peru, some samples of a puzzling Pottiaceae were found. In this paper, we present our arguments for recognising these plants as a new species and its inclusion in Erythrophyllopsis Broth. Key Results. It differs most saliently from other species of Erythrophyllopsis by the combination of its oblong-ovate to ovate-lanceolate leaves, with usually fragile apex, leaf margins papillose-crenulate from apex to lower third, sometimes erose or crenate, lamina unistratose, occasionally bistratose in patches, costa broad, usually ending below the apex, without dorsal stereids near the apex where they are replaced by cells similar to those of the lamina, and short and straight peristome teeth. Conclusions. A new moss species, Erythrophyllopsis perlaticosta M.J.Cano & J.A.Jiménez, is described and illustrated from the Andean highlands in central and northern Peru. A revised identification key for the species of Erythrophyllopsis is also provided. This species grows in crevices or fissures of calcareous rocks or banks between 3050 and 4700 m. The principal distinctive characters that separate it from the nearest species of Erythrophyllopsis and related genera such as Bryoerythrophyllum P.C.Chen and Mironia R.H.Zander are discussed.

    Herzog Vindicated: Integrative Taxonomy Reveals That Trichostomum brachydontium (Pottiaceae, Bryophyta) Comprises Several Species
    (2022-01-21) Porley, Ron D.; Ros Espín, Rosa María; Werner, Olaf; Biología Vegetal
    The morphologically variable moss Trichostomum brachydontium is very common in south and west Europe, particularly under Mediterranean and Atlantic climates. A morphological study was conducted alongside a molecular phylogenetic study based on nr ITS and cp-rbcL regions in order to assess if T. brachydontium is an exceptionally polymorphic species as evidenced by the number of described infraspecific taxa in the last century or, alternatively, if it includes more than one species, and if so, to find the valid name for them. Phylogenetic analyses of both nuclear and chloroplast datasets show that there are four well-supported clades. While the ITS-based tree is in good agreement with the morphological data, there are a few inconsistencies with reference to the rbcL tree; this may be explained by incomplete lineage sorting by hybridization or by the persistence of isolated ancestral molecular races. The morphological survey revealed well-defined discriminate differences between the four phylogenetic lineages. The taxonomic conclusions include the recognition of four species: T. brachydontium s.s., T. herzogii (a new name proposed for var. cuspidatum), T. littorale, and T. meridionale (a new name proposed for var. densum). Lectotypes are designated for T. brachydontium and T. littorale. Our results underline the ongoing need of integrative studies to examine further the underestimated diversity of the T. brachydontium complex in other regions.

    Hymenostylium chapadense M.J.Cano & J.A.Jiménez (Pottiaceae), a new species from Brazil and its phylogenetic position based on molecular data
    (Taylor and Francis Group, 2022-03-18) Martínez, Mónica; Cano Bernabé, María Jesús; Guerra Montes, Juan; Jiménez Fernández, Juan Antonio; Biología Vegetal
    In the context of a taxonomic revision of the tribe Pleuroweisieae in South America, we studied a specimen of Hymenostylium that did not match any previously known species of this genus in America. Here we present our arguments for recognising this moss as a new species.The morphology of the potential new species was compared with that of the species of Hymenostylium presently recognised. A phylogenetic analysis based on the nuclear ITS and plastid rps4 regions was performed to investigate relationships between the new species and closely related taxa. Based on morphological and molecular data, we describe this new species from Brazil, Hymenostylium chapadense M.J.Cano & J.A.Jiménez. The species is strikingly distinguished by a stem with central strand and hyalodermis, oblong-ligulate to oblong-elliptical leaves that are when dry slightly crisped in the upper part and usually constricted just above the base and recurved on one side in the lower third, with uni- to bistratose margins, obtuse apex, costa wide and ending below the apex or percurrent with ventral and dorsal surface cells of the costa differentiated as an epidermis, and middle laminal cells usually with a simple, coarse, central papilla. Our molecular study placed H. chapadense as sister to H. hildebrandtii (Müll.Hal.) R.H.Zander. Possible confusion with the latter species and other closely related taxa is discussed. A key to the South American species of Hymenostylium is provided.

    Taxonomic revision of Chiololoma (Pottiaceae, Bryophyta)
    (Missouri Botanical Garden Press, 2019-11-18) Alonso García, Marta; Cano Bernabé, María Jesús; Jiménez Fernández, Juan Antonio; Biología Vegetal
    A worldwide taxonomic revision of the species belonging to the moss genus Chionoloma Dixon (Pottiaceae) is here presented. Our work is based on the morphological analysis of more than 2600 specimens deposited in different herbaria or collected during field trips. A total of 131 names were found and their nomenclatural types were examined, resulting in the lectotypification of 45 names. It is concluded that Chionoloma is composed of 22 species and one variety, seven of them are here newly combined (C. circinatum (Besch.) M. Alonso, M.J. Cano & J.A. Jiménez; C. cylindrotheca (Mitt.) M. Alonso, M.J. Cano & J.A. Jiménez; C. hyalinoblastum (Broth.) M. Alonso, M.J. Cano & J.A. Jiménez; C. melanostomum (Mitt.) M. Alonso, M.J. Cano & J.A. Jiménez; C. orthodontum (Müll. Hal.) M. Alonso, M.J. Cano & J.A. Jiménez; C. sarawakense (Dixon) M. Alonso, M.J. Cano & J.A. Jiménez; and C. stenocarpum (Thér.) M. Alonso, M.J. Cano & J.A. Jiménez). Moreover, 42 names are newly synonymized and a total of 74 new records for various countries are reported. Keys, descriptions, illustrations, photographs, and distribution data of each species are provided.
