A revision of the genus Absconditella in the Netherlands resulted in the discovery of a new species—A. rubra. A formal description is given as well as notes on other Absconditella species mainly from the Netherlands. It is the first known real epiphytic species of the genus Absconditella s.l. in Europe. A key to the ten known Absconditella species in Europe is provided. © 2015 Magnolia Press. Source

Fungal Biology

Lichenicolous fungi are obligately lichen-associated organisms that have evolved many times throughout the Ascomycota and Basidiomycota. Approximately 20. % of lichenicolous ascomycetes are recognized only from asexual (anamorphic) characteristics, so the phylogenetic position of many groups has never been resolved. Here we present the first molecular phylogeny of Lichenoconium, a genus of strictly asexual, obligately lichenicolous species with broad geographic distributions and diverse host ecologies. We obtained nuclear and mitochondrial rDNA sequences from fungal cultures isolated from four species in the genus, including a new species, Lichenoconium aeruginosum sp. nov., collected in France, Luxembourg and Netherlands. Our multilocus phylogeny supports the monophyly of fungi in the genus Lichenoconium, and places the genus in the Dothideomycetes, an ascomycete class made up mainly of saprobes and plant-associated endophytes and pathogens. There are only a few recognized groups of lichen-formers in the Dothideomycetes, but Lichenoconium is not supported as being closely related to any of these, nor to any other recognized order within the Dothideomycetes. Given that Lichenoconium is but one of over 100 genera of anamorphic lichenicolous fungi, most of which have never been studied phylogenetically, we suggest that asexual lichenicolous fungi may represent novel and evolutionarily significant phylogenetic groups in the Kingdom Fungi. © 2010 The British Mycological Society.

The taxonomic position of several European corticolous lichen species with conspicuous pycnidia and chlorococcoid photobiont is currently unsatisfactory and is here examined with maximum parsimony, maximum likelihood and Bayesian inferences using mtSSU sequences. Lecidea doliiformis is resolved as a member of the Micarea assimilata-group and Catillaria alba as sister to the recently described Biatora ligni-mollis. Therefore, L. doliiformis is transferred to Micarea M. doliiformis (Coppins & P. James) Coppins & Srus. comb. nov., and a new name is introduced for the transfer of C. alba into Biatora (B. veteranorum Coppins & Srus. nom. nov.). Biatora ligni-mollis, recently described from primary forests in British Columbia (Canada), is shown to be a rare but widespread species in Western Europe (Belgium, France, Germany, Poland and Scotland) where it is not confined to undisturbed forests. © 2010 The American Bryological and Lichenological Society, Inc.

Detailed anatomical and chemical studies conducted on recent collections made in almost all suitable habitats on Réunion, a small remote tropical island in the Indian Ocean, yielded a surprising diversity in the widespread lichen genus Micarea (Pilocarpaceae, Lecanorales). Twenty-one species are recognized, including 13 described here as new to science. They are: Micarea alectorialica, M. bebourensis, M. borbonica, M. boryana, M. cilaoensis, M. hyalinoxanthonica, M. isidiosa, M. melanoprasina, M. pseudocoppinsii, M. pseudolignaria, M. sublithinella, M. takamakae and M. tenuispora. Notes on local ecology and important biogeographical features are also given and a key to the species is provided. Isidiiform areolae are reported for the first time in the genus (M. isidiosa and M. tenuispora), as well as the production of protolichesterinic and confluentic acids (M. sublithinella and M. takamakae, respectively). Two groups within the genus are species-rich on the island: the M. peliocarpa group with possibly 5 species, including 3 new to science, and the M. prasina group with 4 species, including 2 new to science. Micarea levicula is reported here for the first time since its description, and the status of the material that can be referred to M. micrococca s. lat. needs further study. © British Lichen Society 2014.

Lecania chlorotiza and L. falcata, described here as new from Spain/Navarra, the Canary Islands and the Azores, do not belong to Lecania s. str. They belong to a strongly supported clade comprising Bacidia, Bacidina, Scutula and Toninia when examined with maximum parsimony, maximum likelihood and Bayesian inferences using mtSSU, nuLSU and nuITS sequences. This clade represents the Bacidiaceae and is included in the Ramalinaceae s. lat. Most genera included in that family need further work before a new genus can possibly be described for Lecania chlorotiza and L. falcata. Copyright © British Lichen Society 2012. Source
