    A new species of Chionoloma (Pottiaceae) from Central and South America with a key to Neotropical species of the genus
    (BioOne Digital Library, 2017-09-05) Alonso García, Marta; Jiménez, Juan A.; Cano, María J.; Biología Vegetal
    A new species of Chionoloma Dixon, C. fractum M.Alonso, M.J.Cano & J.A.Jiménez, is described from Central and South America (Argentina, Belize, Bolivia, Brazil, Colombia, Ecuador, Panama, Peru and Venezuela). The species is distinguished morphologically by lanceolate or linear leaves, with apices usually broken, leaf margins strongly sinuous, basal marginal cells forming a V-shaped pattern, dorsal surface cells of the costa quadrate-round and papillose toward apex, costa percurrent or excurrent in a short mucro and central strand present. Drawings and light microscope photographs of the new species are provided. Moreover, the principal distinctive characters that separate it from the nearest species of Chionoloma are discussed and a key to Neotropical species of the genus is provided.

    Fissidens eremicus (Fissidentaceae), a new pseudocryptic African–European species with dimorphic stems
    (Taylor and Francis Group, 2021-05-14) Guerra, Juan; Jiménez, Juan A.; Martínez, Mónica; Cano, María J.; Biología Vegetal
    Within Fissidens subgenus Fissidens, several species are distinguished in Europe. Some of them are easily identifiable by their morphological characters, and others by a combination of these characters and their sexual reproduction structures. The discovery in the south of the Iberian Peninsula of collections similar to F. viridulus (Sw.) Wahlenb. but with dimorphic fronds (male and female plants) like those of F. sublimbatus Grout suggests that an undescribed taxon exists in this region. Nuclear ITS sequences of four samples of this hypothetical new species from southern Spain and 28 specimens of other species of the subgenera Fissidens and Pachyfissidens were studied. Relationships between specimens were explored with maximum likelihood and Bayesian inference analysis. A morphological study comparing the material to F. sublimbatus was also made. Molecular data showed high support for the recognition of a new species that also presents some morphological differences from Fissidens sublimbatus. Consequently, F. eremicus J.Guerra & J.A.Jiménez has been here described as a new species that can be considered as pseudocryptic and is readily confused with F. sublimbatus. This new taxon is known from the Canary Islands, North Africa and south-southeast Spain, colonising loamy-calcareous soils in ravines of places that are generally neither arid nor subject to much rain.

    Integrative taxonomy reveals hidden diversity in the Aloina catillum Complex (Pottiaceae, Bryophyta)
    (MDPI, 2024-02-02) Cano, María J.; Jiménez, Juan A.; Martínez, Mónica; Hedenäs, Lars; Gallego, M. Teresa; Rodríguez, Omar; Guerra, Juan; Biología Vegetal
    Aloina catillum is a variable moss typical of xerophytic environments in the Neotropics, characterized against other closely allied Aloina species with well-differentiated leaf border by its setae twisted to the left throughout. In order to clarify its variability and its relationships with the allied species with differentiated leaf border A. brevirostris, A. obliquifolia, and A. rigida, we performed an integrative study including sequence data from four markers (nuclear ITS, plastid atpB-rbcL, trnG, trnL-F), morphometry, and species assembling by automatic partitioning (ASAP) algorithm. Our data suggest that A. catillum consists of at least three species: A. calceolifolia (an earlier name for A. catillum), and two species described here as a new, A. bracteata sp. nov. and A. limbata sp. nov. This latter species includes the specimens previously identified as A. obliquifolia from South America. Additionally, some morphological and molecular variability was also detected in A. limbata, but was not consistent enough to be recognized taxonomically. The study supports the presence of A. brevirostris in the Neotropics and A. rigida is tentatively excluded from South America. Full descriptions of the A. catillum s.l. species and a diagnostic key to this complex in South America are provided.

    New bryological data for the Balearic Islands. III.
    (Universidad de Murcia. Servicio de Publicaciones, 2021) Sáez, Llorenç; Pinya, Samuel; Lara, Francisco
    Se aportan datos corológicos para 27 briófitos de las Islas Baleares. La mayoría de las citas de esta contribución corresponden a especies relativamente raras de áreas montañosas de las Islas Baleares (principalmente de Mallorca), para las cuales, la información sobre su distribución en el archipiélago es escasa y poco actualizada. Se cita por primera vez la presencia en el archipiélago balear de Hypnum resupinatum, Lewinskya fastigiata y Ptychostomum kunzei. Por otro lado, Epipterygium tozeri constituye novedad para Mallorca. Son destacables las nuevas localidades en Mallorca de Plagiochasma appendiculatum, una especie amenazada en Europa.

    New chorological data on Hedwigia striata (Bruch & Schimp.) Bosw., (Hedwigiaceae, Musci) in Spain, and remarks on its morphological characters
    (Servicios de Publicaciones Universidad de Murcia, 2014) Gallego Morales, María Teresa; Cano Bernabé, María Jesús; Guerra Montes, Juan
    Hedwigia striata (Bruch & Schimp.) Bosw., a neglected species known in Spain only from a single and old collection of the early 20th century in Cáceres, is newly reported from Ávila, Burgos, Ciudad Real, La Coruña, León, Lugo, Orense, Salamanca, Teruel and Zamora. With these new localities, its distribution range in the Iberian Peninsula it expanded, since it was recorded mainly from Portugal. Diagnostic characters and differentiation from closely related European taxa are discussed. The species is illustrated.

    New synonyms and typifications in Chionoloma tenuirostre (Pottiaceae, Bryophyta)
    (Magnolia Press, 2018-10-24) Alonso García, Marta; Jiménez, Juan A.; Cano, María J.; Biología Vegetal
    Names within Chionoloma tenuirostre are evaluated for proper taxonomic position. A total of 20 names are treated as synonyms, among them, 10 are here synonymised for the first time (Hyophila acutiuscula, Leptodontium subintegrum, Oxystegus cylindricus var. filifer, Trichostomum angustifolium, T. fallax, T. fallax f. minutum, T. fragilifolium, T. prionodon, T. siamense and T. uncinifolium) and three names are excluded from the synonymy (Barbula wollei, Tortula cylindrotheca and Trichostomum burmense). In order to maintain nomenclatural stability, the typification of 12 names is discussed and lectotypes are designated.

    The complete mitochondrial genome of the moss Oxystegus tenuirostris (Hook. & Taylor) A.J.E. Sm. (Pottiaceae, Bryophyta)
    (Taylor and Francis Group, 2015-09-11) Alonso García, Marta; Medina, Rafael; Cano, María Jesús; Jiménez, Juan Antonio; Goffinet, Bernard; Biología Vegetal
    The mitochondrial genome of mosses is characterized by a highly conserved structure and genic content. This is confirmed here through the assembly and annotation of the mt genome of the moss Oxystegus tenuirostris, family Pottiaceae, for which it is assembled. A phylogenetic tree is inferred from the whole genome of 16 species of mosses to validate the sequence of O. tenuirostris by confirming its shared ancestry with Syntrichia. The genome is 105 001 bp long, with a GC content of 39.2%, comprising 40 protein coding, 24 tRNA, and 3 rRNA genes. All introns reported from the mt genome of all but one peristomate moss are present, whereas no region of 50 bp or more is repeated within the genome. The genic content and order is identical to that of most mosses, highlighting that the mt genome is static not only across the phylogenetic depth but also breadth of the moss tree of life.

    Untangling Pseudocrossidium crinitum s. l. (Pottiaceae, Bryophyta) through molecular and morphometric analysis
    (Schweizerbart Science Publishers, 2016-02-01) Cano, María J.; Jiménez, Juan F.; Alonso García, Marta; Jiménez, Juan A.; Biología Vegetal
    Pseudocrossidium crinitum, a dioicous moss distributed mainly in the Southern Hemisphere, has been treated as a single species, in spite of its phenotypical variability. Morphometric methods (PCA; DA) based on quantitative characters and molecular variation using plastid regions trnL-F and trnG of this species, as presently circumscribed, were analyzed. The results suggest that this putative taxon consists of at least five different species, which could belong to different lineages in Pottiaceae. They are Pseudocrossidium crinitum, the neglected P. carinatum, and Barbula santiagensis and two names resurrected from synonymy, Barbula arenicola, and B. flagellaris var. denticulata, which are here combined in Pseudocrossidium.
