Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys biodiversity inventories. Atlantic Forest, most endangered ecosystems world, have high endemism radiated recently Pliocene. We aimed to (1) compile an extensive Forest data set on vascular, non-vascular plants (including hemiepiphytes), lichen epiphyte species occurrence abundance; (2) describe distribution order indicate future sampling efforts. Our work presents first with information abundance...
Abstract While the phylogenetic position of Trypetheliaceae has been subject recent molecular studies, relationships within this family have little studied. Here we construct a detailed genus‐level phylogeny family. We confirm previous morphology‐based findings suggesting that substantial proportion genera are not monophyletic, and an overemphasis placed on certain character state combinations which do strictly reflect relationships. Specifically, patterns ascospore septation, ostiole...
Abstract We provide an expanded and updated, 2-locus phylogeny (mtSSU, nuLSU) of the lichenized fungal family Trypetheliaceae , with a total 196 ingroup OTUs, in order to further refine generic delimitations species concepts this family. As result, following 15 clades are recognized as separate genera, including five newly established genera: Aptrootia Architrypethelium Astrothelium (including bulk corticate astrothelioid ascospores; synonyms: Campylothelium Cryptothelium Laurera ),...
Applying molecular methods to fungi establishing lichenized associations with green algae or cyanobacteria has repeatedly revealed the existence of numerous phylogenetic taxa overlooked by classical taxonomic approaches. Here, we report taxonomical conclusions based on multiple species delimitation and validation analyses performed an eight-locus dataset that includes world-wide representatives dolichorhizoid scabrosoid clades in section

Six species of Punctelia with black lower surface lacking vegetative propagules are taxonomically revised. Lectotypes designated for P. borrerina, microsticta and Parmelia borreri var. allophyla. involuta Canêz & Marcelli is described as new. allophyla Kremp. regarded a synonym borrerina (Nyl.) Krog, instead (Müll. Arg.) previously thought. jujensis Adler recorded the first time Brazil. All this group occur in
Parmotrema is a genus of major interest in the lichen flora Mato Grosso do Sul state, Brazil, since many its species are sources important bioactive compounds. screminiae Spielmann & Canez, novel species, noteworthy source norlobaridone (a depsidone), protolichesterinic acid and atranorin depside). Extract composition was determined by TLC NMR techniques ( 1 H, 13 C, DEPT-135). The acetone extract evaluated for antibiotic activity against Gram-negative Escherichia coli, ATCC 25922)...
The diversity of Leptogium has been underestimated in Mato Grosso do Sul, Brazil. Nine species are being reported for the first time to state, including L. microcarpum, as new record Brazil; and cyanizum, American continent. Furthermore, hondae, moluccanum var. denticulatum quilombensis proposed science. key is provided this region, which can also be used surrounding regions
A sensibilidade de Abelmoschus esculentus ao ozônio (O3) foi determinada em plantas expostas por quatro dias, seis horas/dia, ar filtrado (AF) e AF enriquecido com 80 ppb O3 (AF+O3), câmaras fumigação, analisando-se sintomas foliares visíveis alterações nas trocas gasosas antioxidantes. Avaliaram-se os diariamente as antioxidantes (ácido ascórbico superóxido dismutase) fim do experimento. Todas AF+O3 apresentaram foliares, caracterizados pontuações avermelhadas na superfície adaxial, entre...
Specimens of Leptogium collected in ten localities from the State Rio Grande do Sul were studied. Sixteen species found 28 records mentioned to state, which represents around 57% diversity known for Sul. exaratum is proposed as a new species. atlanticum, L. milligranum and vesiculosum are reported first time state. The lectotype javanicum here detailed descriptions provided examined specimens. An identification key showed with all Leptogium. It published taxonomic Sul, highest this genus Brazil.
Abstract Ephebe brasiliensis is a semi-aquatic fruticose cyanolichen that occurs in freshwater environments from Brazil (Minas Gerais and São Paulo states) Uruguay. Although this species may be locally abundant has "wide" distribution, it been poorly studied still misunderstood with respect to their distribution ecological characteristics. Herein, E. reported for the first time Southern Brazil.
The lichen family Parmeliaceae is among the best studied groups of lichens. Canoparmelia amazonica, Myelochroa lindmanii, and Parmelinella salacinifera are species that have yet to be in detail with molecular methods. This study used analyses ITS sequences examine phylogenetic position these three species. amazonica M. lindmanii were recovered within rather than genera which they currently assigned. While for P. we confirmed its genus. Chemical morphological descriptions provided, generic...
ABSTRACT Previously known only from the North and Central America, lichenized fungi Cladonia dimorphoclada Robbins is recorded for first time in South America. The specimens were found growing on soil, an open area at 1695 m alt., Southern Brazil. We present a distribution map, figures, comments.
