Integrative taxonomy reveals hidden diversity in the Aloina catillum Complex (Pottiaceae, Bryophyta)
(MDPI, 2024-02-02) Martínez, Mónica; Hedenäs, Lars; Rodríguez, Omar; Cano Bernabé, María Jesús; Gallego Morales, María Teresa; Guerra Montes, Juan; Jiménez Fernández, Juan Antonio; 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.

A molecular approach to the phylogeny of the moss genus Pseudocrossidium (Pottiaceae, Bryopsida) and its taxonomic implications
(Wiley, 2022-08-12) Cano Bernabé, María Jesús; Gallego Morales, María Teresa; Guerra Montes, Juan; Jiménez Fernández, Juan Antonio; Biología Vegetal
Pseudocrossidium is a genus of 21 species belonging to the Pottiaceae with the highest concentration of taxa and morphological variation found in South America. To investigate the evolutionary relationships among the species of Pseudocrossidium and other members of the Pottioideae, molecular phylogenetic reconstructions, using the nuclear ITS1‐5.8S‐ITS2, and the plastid atpB‐rbcL, trnG, and trnL‐F, has been performed because this genus has only been partially tested using molecular markers. Bayesian and maximum likelihood topologies show that the genus, as presently circumscribed, is polyphyletic. Consequently, the circumscription of Pseudocrossidium is amended and numerous taxonomic changes resulting from the molecular, morphological, and nomenclatural studies are proposed. The phylogenetic and morphologically divergent Pseudocrossidium mendozense is renamed as Gertrudiella mendozensis. Pseudocrossidium linearifolium and P. porphyreoneurum are representatives of the new genera Barbulastrum and Helicobarbula, respectively. Pseudocrossidium carinatum and P. santiagense are accommodated in a new genus Austrobarbula. Aloinella, nested in a paraphyletic Pseudocrossidium, is maintained at generic rank, apparently derived from Pseudocrossidium. Barbula integrifolia, B. riograndensis, and Tortula jaffuelii are transferred to Pseudocrossidium. The remaining species of Pseudocrossidium are maintained in this genus, pending further studies. Conflicts of the trees observed could be evidence of interspecific or intergeneric gene flow in various lineages in the Pottioideae.

Bryophyte diversity in the Guadiamar river basin (SW of Spain)
(Murcia: Universidad de Murcia, Servicio de Publicaciones, 2002) Cano Bernabé, María Jesús; Gallego Morales, María Teresa; Guerra Montes, Juan; Jiménez Fernández, Juan Antonio; Ros Espín, Rosa María; Sin departamento asociado; Facultad de Biología
A study of the bryophyte flora of the Guadiamar river basin (southwes tern Spain) was carried out. Forty-one localities along this river and its main tributaries were sampled. A total of 123 taxa are mentioned, of which 93 are mosses, 27 liverworts and 3 hornworts. Scopelophila cataractae (Mitt.) Broth., which grows exclusively on soils rich in heavy metals, is the second record from the Iberian Peninsula

Schistidium convergens (Grimmiaceae, Bryophyta), a new species from southern Spain and Morocco
(Schweizerbart Science Publishers, 2019-04-25) Jiménez-Martínez, Juan F.; Alonso García, Marta; Cano Bernabé, María Jesús; Gallego Morales, María Teresa; Guerra Montes, Juan; Biología Vegetal
Schistidium convergens is described as a new species from southern Spain and northern Morocco, based on morphological and molecular data. The species is fully described and illustrated, its affinities are discussed in detail, and its current distribution mapped. The species is distinguished morphologically by its usually smooth leaf margins, sometimes with short papillae towards the leaf apex, recurved from the leaf base to the apex on both sides, rectangular basal leaf cells, quadrate to short-rectangular, subhyaline basal marginal cells with slightly thickened transverse walls, and irregular, isodiametric, quadrate to short rectangular, sometime oblate distal and medial exothecial cells. A table with characters to distinguish this species from S. apocarpum, the morphologically most similar species, and a phylogenetic analysis in order to detect relationships of the new species with nearby taxa based on the rDNA ITS region are provided. The new species is located in a clade with S. confertum, S. marginale and S. frigidum, among others.

Circumscription and phylogenetic position of two propagulose species of Syntrichia (Pottiaceae, Bryophyta) reveals minor realignments within the tribe Syntricheae
(MDPI, 2022-02-25) Cano Bernabé, María Jesús; Gallego Morales, María Teresa; Guerra Montes, Juan; Jiménez Fernández, Juan Antonio; Biología Vegetal
In the course of a worldwide revision of the genus Syntrichia, we identified problems in the circumscription of some species of the genus as well as among some allied genera grouped in the tribe Syntricheae. This is the case for the two propagulose Syntrichia amphidiacea and S. gemmascens, closely related to Streptopogon. We analyzed phylogenetic relationships between these species, based on nuclear (ITS) and two plastid (trnL-F and trnG) markers and morphological features. Species delimitation using molecular data was consistent with our preliminary morphological inference. Phylogenetic analyses were performed using maximum likelihood and Bayesian inference methods. Our results placed Syntrichia amphidiacea in the Streptopogon clade. Syntrichia gemmascens is also included in Streptopogon in spite of the discrepancy of the ITS and plastid relationships, which could be evidence of an exchange of genetic material between species in various lineages in the Pottioideae. Streptopogon is maintained as a separate genus on the basis of morphology characters, and we consider the differentiation of laminal papillae and the presence of a stem central strand as new characters in the genus. We accept Sagenotortula as distinct genus sister to Syntrichia. We consider the lack of costal dorsal epidermis and the differentiation of a crescent-shaped costal dorsal stereid band as distinctive generic characters in Syntrichia. Additionally, we include Syntrichia percarnosa as a new synonym for S. breviseta. Three names are lectotypified.

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) Cano Bernabé, María Jesús; Gallego Morales, María Teresa; 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.
