“…In the present study, yet another new genus, Emmanuelia, is erected to accommodate a group of lobarioid lichens that cannot be placed in any of the existing genera. The species of interest belong to a lineage mostly restricted to the Neotropics and the southeastern United States, and were previously treated as members of the genus Lobaria and subsequently considered part of Ricasolia (Moncada et al 2013;Käffer et al 2016;Lehnen et al 2017;Etayo et al 2018). Yoshimura (1998) treated the South American taxa as L. quercizans group, also implying a close relationship to Ricasolia.…”

The former family Lobariaceae, now included in Peltigeraceae as subfamily Lobarioideae, has undergone substantial changes in its generic classification in recent years, based on phylogenetic inferences highlighting the polyphyly of the speciose genera Lobaria, Pseudocyphellaria and Sticta. Here we introduce the new genus Emmanuelia, named in honor of Prof. Emmanuël Sérusiaux for his extensive work on the Peltigerales. Emmanuelia currently comprises twelve species. It is superficially similar to the lobarioid genus Ricasolia, but differs by its apothecia, rimmed by overarching and often crenulate to lobulate margins, with the parathecium (proper excipulum) and the amphithecium (thalline excipulum formed by the thallus cortex) apically separated and of a different structure. Also, ascospore dimensions and shape differ between the two genera, with the ascospores of Emmanuelia being longer and narrower. Molecular phylogenetic analyses using DNA nucleotide sequences of the internal transcribed spacer region (ITS) and the small subunit of mitochondrial ribosomal DNA (mtSSU) confirm that Emmanuelia belongs to the Lobaria s.lat. clade and forms a monophyletic group sister to the lineage consisting of Dendriscosticta, Lobariella and Yoshimuriella. None of the available generic names of lobarioid lichens can be applied to this group, and consequently a new name is proposed for this new genus, which is typified with E. ravenelii comb. nov. Eleven other species are transferred to Emmanuelia: E. americana comb. nov., E. conformis comb. nov., E. cuprea comb. nov., E. elaeodes comb. nov., E. erosa comb. nov., E. excisa comb. nov., E. lobulifera comb. nov., E. ornata comb. nov., E. patinifera comb. nov., E. pseudolivacea comb. nov. and E. tenuis comb. nov. The genus is represented in North America by three species, including E. lobulifera, which is resurrected from synonymy with E. (Lobaria) tenuis, a South American species, and E. ornata, whose populations were previously treated under E. (Lobaria) ravenelii.

“…Desde o século XIX os liquens são utilizados como indicadores ambientais, originando diversas pesquisas visando o monitoramento ambiental, seja por meio de estudos para avaliar a qualidade do ar em ambientes urbano/ industriais (Le Blanc & De Sloover 1970, Martins et al 2008, Käff er et al 2012) ou em áreas fl orestais (Hauck et al 2013, Käff er & Martins 2014, Käff er et al 2015, 2016a.…”

RESUMO -O objetivo do estudo foi analisar a composição e estrutura da comunidade de liquens foliosos e fruticosos corticícolas em área urbana e rural do município de Novo Hamburgo, RS. Foram analisados dez forófi tos em cada área e o mapeamento das espécies realizado pelo método do acetato. Foram analisados os parâmetros: riqueza, frequência, cobertura e valor de importância em cada área. No total foram identifi cadas 55 espécies para as duas áreas. A riqueza foi similar entre as áreas: urbana (33) e rural (32). As espécies mais frequentes foram Dirinaria picta (Sw.) Clem. & Shear e Parmotrema reticulatum (Nyl.) Hale, enquanto Canoparmelia texana (Tuck.) Elix & Hale e Parmotrema tinctorum (Nyl.) Hale obtiveram os maiores valores de importância. A área rural apresentou melhores condições para o desenvolvimento dos liquens. Este trabalho contribui para o conhecimento da micobiota na região, podendo ser utilizado em futuros estudos de monitoramento ambiental.

In this paper we analyzed the composition and the corticolous lichen community structure of foliose and fruticose species in urban and rural areas in the municipality of Novo Hamburgo, RS. We analyzed ten phorophytes in each area and mapped species by using the acetate method. The parameters analyzed in each area were: richness, frequency, coverage and importance value. A total of 55 lichen species were identifi ed for both areas. Richness was similar among areas: urban (33) and rural (32). The most common species were Dirinaria picta (Sw.) Clem. & Shear and Parmotrema reticulatum (Nyl.) Hale, while Canoparmelia texana (Tuck.) Elix & Hale and Parmotrema tinctorum (Nyl.) Hale, had the highest importance values. The rural area had better conditions for lichen development. This work contributes to the knowledge of the mycobiota in the region and may be used for future studies on environmental monitoring.
