The lichen family Teloschistaceae is one of the larger families lichenized fungi. Currently it includes very large heterogenous genus, Caloplaca , with some 1000 or more species a vast variation in morphology, anatomy and chemistry. rest split into 10–15 smaller genera, each 20 fewer species. There no modern classification based on molecular data. Here we attempt first phylogenetic evaluation part family, including total 337 Of these, 162 were used combined analysis ribosomal RNA sequence...
The number of undescribed species lichenized fungi has been estimated at roughly 10,000. Describing and cataloging these would take the existing taxonomists several decades; however, support for taxonomy is in decline worldwide. In this paper we emphasize dire need taxonomic expertise lichenology. We bring together 103 colleagues from institutions worldwide to describe a total 100 new fungi, representing wide geographic range. newly described are: Acarospora flavisparsa, A. janae,...
Abstract A new taxonomy of the Caloplaca citrina group in Black Sea region is presented. It based on nrDNA ITS molecular data, chemistry (anthraquinone contents) and 20 morphological characters. Six species previously known are accepted: arcis , C. calcitrapa dichroa flavocitrina geleverjae limonia . Five described: arcisproxima austrocitrina communis confusa nigromarina Seven further species, britannica marina maritima microthallina ora phlogina also treated briefly. Some maritime from...
Abstract Background In light of the biodiversity crisis and our limited ability to explain variation in biodiversity, tools quantify spatial temporal its underlying drivers are critically needed. Inspired by recently published ecospace framework, we developed tested a sampling design for environmental biotic mapping. We selected 130 study sites (40 × 40 m) across Denmark using stratified random along major gradients variation. Using standardized methods, collected site species data on...

Abstract Gyalolechia fruticum , a new epiphytic species with Mediterranean-Macaronesian distribution, is described. It differs in molecular data and ecology from two closely related calcicolous species, G. luteococcinea marmorata both formerly called Caloplaca subochracea auct. The grows on coastal shrubs (rarely wood), accompanied by species-rich communities of maritime lichens. typical habitat undisturbed sand dunes, under dry conditions frequent spells humid air the sea. so far known...
Abstract Using ITS nrDNA sequence data, the Caloplaca cerina group ( Teloschistaceae ) is defined here as a monophyletic, but internally richly branched lineage. The also characterized by combination of morphological and anatomical characters. Its internal lineages are supported phenotypic characters in addition to ecology distribution. Within large C. group, we have found at least 20 phylospecies temperate zone Northern Hemisphere. Two species complexes do not produce any vegetative...
Abstract Two surveys of the lichen and bryophyte flora growing on oak twigs from a Welsh Danish locality were compared with additional data bark pH % nitrogen in thalli Hypogymnia physodes . Despite differences climate flora, both sites showed shift communities sensitive (nitrophobe) to tolerant (nitrophile) species, which was correlated increasing an increase total H. The floristic survey Wales repetition study eight years earlier (Wolseley & Pryor 1999) now showing loss nitrophobes all...
Abstract A new genus, Catenarina ( Teloschistaceae , Ascomycota), with three species is described from the Southern Hemisphere, supported by molecular data. All contain secondary metabolite 7-chlorocatenarin, previously unknown in lichens. desolata a non-littoral, lichenicolous found on volcanic and soft sedimentary rock at 190–300 m near steppes southernmost Chile subantarctic island, Kerguelen. vivasiana grows maritime rocks outcrops lowland Nothofagus forests, but has also been altitudes...
Abstract Based on a combined three locus analysis two new genera, Charcotiana and Amundsenia, are proposed in the lichen family Teloschistaceae , subfamily Xanthorioideae . includes species C. antarctica which is known only from continental Antarctica. The bipolar genus Amundsenia A. austrocontinentalis also Antarctica, Arctic Caloplaca approximata here into genus. genera phylogenetically distinct, but poor morphological characters; consist mainly of minute apothecia cracks rocks located...
23 species of the lichen genus Caloplaca from Svalbard are described and/or discussed. The descriptions natural language based on characters for each coded into LIAS (Global Information System Lichenized and Non-Lichenized Ascomycetes). A total 37 listed Svalbard, which two species: C. elvebakkiana scabrosa as new to science. alaskensis is recorded first time Svalbard. key known provided.
Abstract Blastenia is a widely distributed lichen genus in Teloschistaceae. We reconstructed its phylogeny order to test species delimitation and find evolutionary drivers forming recent diversity. The origin of dated the early Tertiary period, but later diversification events are distinctly younger. recognized 24 (plus 2 subspecies) within 6 infrageneric groups. Each strongly prefers single type substrate (17 occur on organic substrates, 7 siliceous rock), most groups also show clear...
Abstract: The xanthorioid taxa Xanthomendoza borealis and Xanthoria mawsonii are revised using morphological, anatomical, secondary chemical, molecular characters. We conclude that most specimens determined as X . from the Antarctic conspecific with labelled Northern Hemisphere. Some named wrongly of candelaria (L.) Th. Fr, including holotype C. W. Dodge. Accordingly, Dodge is a synonym to Fr. only available correct name for bipolar species, which comprises material previously X. , distinct...
The lichen family Teloschistaceae from the Galapagos is revised. Most of species belong to Caloplacoideae, two Teloschistoideae and a few Xanthorioideae, three subfamilies not validly published, which remedied here. Four different datasets were analyzed using Bayesian inference. For bulk species, combined dataset nrITS, nrLSU mrSSU was analyzed. Additionally, analyses performed nrITS further investigate phylogenetic relationships within between in each subfamily, genera Xanthomendoza...
Abstract Aim The homogenisation of historically isolated gene pools has been recognised as one the most serious conservation problems in Antarctic. Lichens are dominant components terrestrial biotas Antarctic and high mountain ranges southern South America. We study effects dispersal strategy migration history on their genetic structure to better understand importance these processes interplay shaping population well relevance for conservation.

The phylogenetic relationships of the lichen genus Placopsis and related genera in Agyriales were analyzed using molecular data. We obtained a total 66 new sequences from nuclear ITS, LSU mitochondrial SSU rDNA. Phylogenetic analyses conducted Bayesian maximum-parsimony framework.

A morphological character supporting Placopsis-Orceolina clade non-amyloid ascus. section Aspiciliopsis as defined by sunken fruiting...
The recently invalidly published name Teloschistaceae subfam. Teloschistoideae Arup, Søchting & Frödén nov. is validated here by providing a diagnosis for the taxon (ICN Art. 38).
