The moss genus Andreaea Hedwig (1801:47) (Andreaeaceae Dumort., Bryophytina Engl.) is found growing on acid and neutral rocks in cool temperate to subpolar environments, as well as in the high altitude mountains of tropical and subtropical regions (Murray 1988). The genus include between 15 and 20 species in the Andean region (Churchill et al. 2020...
Platanus × acerifolia is used as an urban shade tree in many cities throughout Argentina. In late autumn and winter of 2023, leaves and fruits of P. × acerifolia showing typical symptoms of a powdery mildew were collected along the main streets of Tucumán, Argentina. Its morphology and comparison with published descriptions allowed us to identify t...

Background and aims: In the course of floristic dry forest sampling, specimens of Venturiella acrifolia were collected in Santiago del Estero and Santa Fe provinces. This record constitutes the first report in Argentina and the second in South America. M&M: Specimens collected in 2019 and 2023 were analyzed morphologically using conventional techni...
Divergence times based on molecular clock analyses often differ from those derived from total‐evidence dating (TED) approaches. For bryophytes, fossils have been excluded from previous assessments of divergence times, and thus, their utility in dating analyses remains unexplored. Here, we conduct the first TED analyses of the complex thalloid liver...
Octospora tucumanensis, a new bryophilous ascomycete infecting rhizoids of the pleurocarpous moss Dimerodontium balansae (Fabroniaceae), is described and illustrated based on collections from Argentina.

Liverworts are known for their large chemical diversity. Much of this diversity is synthesized and enclosed within the oil bodies (OB), a synapomorphy of the lineage. OB contain the biosynthetic enzymes to produce and store large quantities of sesquiterpenoids and other compounds while limiting their cytotoxicity. Recently, there were important bio...
PRESENTACIÓN
Buena parte de los tucumanos viven en lo que se conoce como el Gran San Miguel de Tucumán: Yerba Buena, Tafí Viejo, Lules, La Banda, El Manantial, Las Talitas y San Miguel de Tucumán, con alrededor de un millón de tucumanos, son vecinos de la Sierra de San Javier. Esa sierra fue durante siglos fuente de madera y de pastos verdes para...
Anaschisma, a new genus of Pottiaceae, is distinguished from both Tortella and Trichostomum by the caducous, cleistocarpous capsule, and from Aschisma by capsule dehiscence irregular, not circumscissle. It is similar to Aschisma in the denticulate, weakly bordered cauline leaves, broadest at the base, and tendency to secund leaf stance. Four specie...
In recent years, the use of extensive molecular and morphological datasets has clarified the phylogenetic relationships among the orders of complex thalloid liverworts (Marchantiidae). However, previous studies excluded extinct taxa; thereby, undersampling the actual taxonomic diversity of the group. Here, we conducted a total‐evidence analysis of...
Background and aims: The bryophyte flora of Argentina is currently under study, nevertheless, there are still extensive areas unexplored, such as Santiago del Estero with only three records of bryophytes to the entire region.

We describe the new species Notocynodontium parvulum, in the new genus Notocynodontium, to accommodate a distinct taxon recently found in two widely separated localities in central Chile and the Falkland Islands. Although morphologically reduced, preliminary molecular data indicate that the taxon belongs to the Rhabdoweisiaceae. The combination of...
Morphological data has gained renewed attention and has been shown to be crucial in clarifying the phylogenetic relationship in a wide range of taxa. In the last decades, phylogenetic analyses of sequence-level data have radically modified the systematic schemes within bryophytes (early non-vascular land plants) and have revealed a widespread patte...
Mosses are a dominant ground cover in a wide array of ecosystems, especially in those developing under cold-stressed environments such as arctic and alpine ice-melting glacial forelands. Consequently, mosses may influence the performance and distribution of other plants. Here, we assessed the nature of interactions between vascular plants and cushi...
During recent botanical surveys undertaken in South America (Uruguay and Paraguay) some of the samples collected were identified as Tortella fruchartii (Müll. Hal.) R. H. Zander and T. lilliputana (Müll. Hal. ex G. Roth) R. H. Zander, two autoicous species of the genus with distribution area restricted to the New World. The former is re-described b...

It remains hotly debated whether latitudinal diversity gradients are common across taxonomic groups and whether a single mechanism can explain such gradients. Investigating species richness (SR) patterns of European land plants, we determine whether SR increases with decreasing latitude, as predicted by theory, and whether the assembly mechanisms d...
As part of the revision of Philonotis in South America, a sample collected in Chile perfectly matched the type specimen of P. brevifolia Herzog. This species described from Chile was considered conspecific with P. krausei (Müll. Hal.)

Al igual que en otras regiones de América del sur, su flora briológica e...
El Noroeste Argentino (NOA) es una de
las regiones de mayor diversidad de especies
vegetales del país, exhibiendo una clara influencia
del Neotropico. Sin embargo, las hepáticas
(Marchantiophyta) no parecen coincidir con tales
patrones de diversidad. Así, el extremo austral
