“…str. : it is made of two different foliose thalli, fixed one to the other or not; the one associated with Nostoc most usually has a typically strongly maculate upper cortex (Magain et al 2012a;Moncada et al 2013b). Dedicated structures including Nostoc colonies (named cephalodia) on the surface of or inside a green thallus do not occur in the genus.…”

“…It is subcosmopolitan, being well-developed and diverse in humid, cool-to warmtemperate environments. It is thus most conspicuous, together with other genera in the Peltigerales such as Lobaria, Peltigera, and Pseudocyphellaria, and representatives of the families Collemataceae and Pannariaceae, in temperate humid coastal areas (northwestern coast of North America, southern Chili, Tasmania, and New Zealand) and in tropical montane forests, with an impressive diversity in the northern Andes in Colombia (Moncada and Lücking 2012;Moncada et al 2013bMoncada et al , c, 2014aSuárez and Lücking 2013). It occurs at low elevation as well, including in tropical areas, with less diversity and biomass, and is completely absent in desert habitats and dry forests.…”

In the framework of a worldwide project on the phylogeny of the lichen genus Sticta, dedicated sampling was performed in four regions of Western Europe, roughly along an east-west line between N 48°02′ E 07°01′ and N 52°01′ W 09°30′, ranging from France/Vosges to Ireland/ Kerry. Five clearly distinct ITS haplotypes were detected for isidia-producing species where only two were expected. Subtle anatomical and morphological characters, together with a strongly supported 4-loci molecular phylogeny, permit distinguishing, besides the easily recognized S. canariensis and S. limbata: 1) the two well-known S. fuliginosa and S. sylvatica, whose type collections have been carefully reassessed; the former is widespread in both hemispheres, while the latter is correctly identified only from continental Europe and the Andes in Colombia. The barcode ITS of S. fuliginosa differs by a single substitution from S. limbata (with a single exception), and the 4-loci phylogenetic tree does not resolve them as distinct lineages, most probably highlighting a very recent divergence and incomplete lineage sorting. 2) Three species that were formely included in S. fuliginosa: the resurrected S. ciliata Taylor, belonging to a complex group yet to be disentangled and occurring in the Neotropics, Africa, Macaronesia, and Western Europe, and two species described as new to science, S. fuliginoides, found in continental Europe, the Canary Islands, eastern North America, and Colombia, and S. atlantica only known from Ireland and the Azores archipelago. Molecular inferences demonstrate active divergence and dispersion within S. ciliata that may require recognition of further species. Fresh material can be identified with a morphological and anatomical preliminary key provided here. We propose that the taxonomy of all lichen species be urgently reviewed in the light of molecular data in an evolutionary context, particularly those used as bioindicators of environmental change and woodland management.

“…Sticta jaguirreana es probablemente el cianomorfo de una especie fotosimbiodémica, ya que presenta las características típicas de los cianomorfos de fotosimbiodemas que se han encontrado en Colombia (Moncada, et al, 2013c). Podría llegar a confundirse con S. phyllidiofuliginosa (ver abajo), de la que se separa por la presencia de tomento secundario y las cifelas grandes con el margen involuto a recto.…”

Traditional taxonomic studies provide only a limited understanding of species richness within a group. Their usefulness for assessing species diversity could also be limited as many lack sufficient sampling and/or fail to integrate different data types for assessing species boundaries. To explore the challenges and limitations of estimating species richness in lichens, we employed an integrative taxonomic approach to elucidate diversification patterns of the genus Sticta (Peltigeraceae) in Puerto Rico. Specimens were collected throughout the island, and a six‐locus dataset was generated to infer phylogenetic relationships among Puerto Rican Sticta and their continental counterparts. Phylogenetic analysis was combined with species delimitation methods and analysis of morpho‐anatomical characters to assess diversity patterns and clarify species‐level taxonomy. We found that Sticta is represented by 16 species in Puerto Rico and that at least 11 (69%) of them are potentially endemic to the island. We describe eight of these in this work: S. borinquensis sp. nov., S. corymbosa sp. nov., S. densiphyllidiata sp. nov., S. guilartensis sp. nov., S. harrisii sp. nov., S. parvilobata sp. nov., S. riparia sp. nov., and S. tainorum sp. nov. These species do not cluster in a monophyletic assemblage but are scattered over the broader Sticta phylogeny, indicating at least eight separate dispersal events. Putative endemic species were found to have close allies occurring in South America. Careful re‐examination of material revealed phenotypical characters that separate most species, suggesting low levels of cryptic diversity. We highlight that integrating molecular methods and other sources of information in species discovery along with comprehensive sampling efforts can greatly enhance our knowledge about diversity patterns in poorly studied groups and regions. Furthermore, species and ecosystems in the Caribbean are being threatened by substantial human‐driven changes (e.g., deforestation, climate change). Consequences of these impacts include reduction in already restricted habitats and potential extinction. We argue that studies analyzing species diversity within a phylogenetic framework could better inform conservation efforts aimed at addressing these challenges.
