Abstract Parmelioid lichens are a diverse and ubiquitous group of foliose lichens. Generic delimitation in parmelioid has been state flux since the late 1960s with segregation large, heterogeneous genus Parmelia into numerous smaller genera. Recent molecular phylogenetic studies have demonstrated that some these new genera were monophyletic, not, others, previously believed to be unrelated, fell within single monophyletic groups, indicating need for revision generic delimitations. This study...
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,...
Significance Macrolichens are considered to be well known, including the tropical montane basidiolichen fungus Dictyonema glabratum , also known as Cora pavonia an important component of threatened paramo ecosystems, where it acts a biological fertilizer due its ability fix atmospheric nitrogen. This lichen was long believed represent single species, but after revising this number 16 in two genera ( and Corella ), here we show that at least 126 phylogenetically morphologically distinct...
Fungal species are not immune to the threats facing animals and plants thus also prone extinction. Yet, until 2015, fungi were nearly absent on IUCN Red List. Recent efforts identify fungal under threat have significantly increased number of published assessments. The 597 in 2022-1 List update (21 July 2022) basis for first global review extinction risk they face. Nearly 50% assessed threatened, with 10% NT 9% DD. For regions a larger assessments (i.e., Europe, North America, South America),...
Phylogenetic diversity of lichen photobionts is low compared to that fungal counterparts. Most fungi are thought be associated with just four photobiont genera, among them the cyanobacteria Nostoc and Scytonema, two most important nitrogen fixers in humid ecosystems. Although many have been identified using isolated cultures sequences, identity Scytonema has never confirmed by culturing or sequencing. We investigated phylogenetic placement presumed unicellular morphotypes previously assigned...
This study elucidates the phylogenetic position of a unique taxon Graphidaceae occurring on rock in coastal desert areas, assessing its importance for our understanding evolution largest family tropical lichenized fungi. •We used maximum likelihood and Bayesian approaches to reconstruct three-gene phylogeny molecular clock approach estimate divergence dates major clades, as well ancestral ecogeography state analysis. •The new genus Redonographa represents subfamily, Redonographoideae, sister...
As part of a larger systematic and taxonomic revision, including molecular phylogenetic analysis, lichenized Basidiomycota in the Dictyonema clade, ten species are described as new from tropical America, seven foliose genus Cora three filamentous Dictyonema: arachnoidea J. E. Hern. & Lücking, sp. nov., C. aspera Wilk, Lücking Morales, byssoidea Moncada, cyphellifera Dal-Forno, Bungartz inversa squamiformis Yánez-Ayabaca, strigosa Paz L.

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 ),...
The anatomy of the endolithic, calcicolous lichen Verrucaria rubrocincta Breuss is described using optical and scanning electron microscopy. This locally abundant in caliche plates open desert pavements Sonoran Desert south-western Arizona. endolithic growth V. distinctly layered. upper layer a fine-grained calcite (micrite). sparsely penetrated by hyphae therefore cannot be interpreted as lithocortex sensu stricto . Beneath micrite photobiont layer. Below this form pseudomedulla penetrating...
ABSTRACT The “species pair” concept obscures both intra‐ and interspecific relationships should be abandoned, evolutionarily taxonomically. Based on our molecular phylogenetic work the genus Roccella we are able to show for first time that sexually vegetatively dispersed entities in an anticipated ( galapagoensis/R. lirellina ) actually form several distinct monophyletic genotypes, here interpreted as species which sexual reproduction has been repeatedly evolved. accepted based a hypothesis...
Usnea species with a red-orange cortical or subcortical pigmentation were studied in the tropical Andes (Venezuela, Colombia, Ecuador, Peru and Bolivia) Galapagos Islands. Sixteen are treated, 14 occurring six Galapagos. crocata, U. grandisora (endemic to Galapagos), rubricornuta subdasaea newly described. dorogawensis, michauxii, subcornuta subrubicunda new South America. Tri-terpenoids detected by thin layer chromatography play an important role taxonomy of this group species. Several...
Abstract Two new species, Placomaronea fruticosa and P. placoidea , are described. They were originally discovered in the southern Peruvian Andes at altitudes between 3000 4650 m. One specimen of was subsequently also found among herbarium material collected Argentina. is terricolous high altitude grasslands with rocky cliffs. It characterized by its fruticose to subfruticose thallus, which up 8 mm tall partially immersed substrate, branches bright deep yellow, flattened on substrate surface...
Abstract Based on morphological, anatomical, chemical, ecological and molecular evidence, Blarneya is synonymized here with Tylophoron . The phylogeny derived from sequences obtained sporodochia of places this genus, described to accommodate an anamorphic lichen white cushion-shaped sporodochia, within This conclusion further supported by the discovery -type ascomata emerging directly thalli producing identical hyaline conidia. In one specimen pycnidia were also observed. represents a...
As part of an ongoing species inventory for the Galapagos Archipelago, sterile leprose and leproid lichens have been revised. Differences between vs. growth forms are discussed in light significant recent advances taxonomy Lepraria.

Sticta is a subcosmopolitan genus most diverse in the tropics. Traditionally, many taxa were considered to be widespread and morphologically variable, following broadly circumscribed morphodemes. Among these S. weigelii morphodeme, characterized by cyanobacterial photobiont rather narrow, flabellate truncate or tapering lobes producing predominantly marginal isidia. Molecular phylogenetic analyses focusing on ITS fungal barcoding marker revealed that this morphodeme represents several...

Abstract: Ramalina species are among the most abundant lichens on Galapagos Isles. A total of fifteen have been distinguished, four which described as new here: darwiniana , R. fragilis furcellangulida and polyforma . These considered to be endemic whereas previous reports refer relatively common, more widely distributed species. Several other reported here for first time from Galapagos.
