“…The Dictyonema-Cora clade appears on a long branch emerging from the Arrhenia grade in our 4-gene backbone analyses and our ITS-LSU analysis. The analyses by Dal-Forno et al (2013) shows the most closely related groups that are basal to Dictyonema are Eonema and Cyphellostereum rather than the more distantly related Arrhenia included in our analyses. In the analysis by Lawrey et al, Acantholichen separates the Cora (D. sericeum-D. minus) and Dictyonema ss.…”

“…Similarly, the combined ITS-LSU-RPB2 analyses by Dal-Forno et al (2013), show Acantholichen as sister to Corella (91 % MLBS, 1.0 B.P. with 88 % MLBS and 1.0 BPP support for the branch that subtends both).…”

In the analyses by Dal-Forno et al (2013), Corella appears as a sister clade to Acantholichen with strong support in their combined ITS-LSU-RPB2 analysis (91 % MLBS; 0.98 BPP).…”

“…sericeum (Sw.) Berk.). Additional species included based on molecular phylogenies of Lücking et al (2009) andDal-Forno et al (2013) Comments While Dictyonema appears as a grade in most analyses, the combination of morphological and ecological characters set it apart, and topological tests cannot reject its potential monophyly. Resurrection of generic names Cora by Lawrey et al (2009) and Corella by Dal-Forno et al (2013) for the disjunct Dictyonema clades shown in Lawrey et al (2009) resolves the problem of polyphyly in this group.…”

Molecular phylogenies using 1-4 gene regions and information on ecology, morphology and pigment chemistry were used in a partial revision of the agaric family Hygrophoraceae. The phylogenetically supported genera we recognize here in the Hygrophoraceae based on these and previous analyses are: Acantholichen, Ampulloclitocybe, Arrhenia, Cantharellula, Cantharocybe, Chromosera, Chrysomphalina, Cora, Corella, Cuphophyllus, Cyphellostereum, Dictyonema, Eonema, Gliophorus, Haasiella, Humidicutis, Hygroaster, Hygrocybe, Hygrophorus, Lichenomphalia, Neohygrocybe, Porpolomopsis and Pseudoarmillariella. A new genus that is sister to Chromosera is described as Gloioxanthomyces. Revisions were made at the ranks of subfamily, tribe, genus, subgenus, section and subsection. We present three new subfamilies, eight tribes (five new), eight subgenera (one new, one new combination and one stat. nov.), 26 sections (five new and three new combinations and two stat. nov.) and 14 subsections (two new, two stat. nov.). Species of Chromosera, Gliophorus, Humidicutis, and Neohygrocybe are often treated within the genus Hygrocybe; we therefore provide valid names in both classification systems. We used a minimalist approach in transferring genera and creating new names and combinations. Consequently, we retain in the Hygrophoraceae the basal cuphophylloid grade comprising the genera Cuphophyllus, Ampulloclitocybe and Cantharocybe, despite weak phylogenetic support. We include Aeruginospora and Semiomphalina in Hygrophoraceae based on morphology though molecular data are lacking. The lower hygrophoroid clade is basal to Hygrophoraceae s.s., comprising the genera Aphroditeola, Macrotyphula, Phyllotopsis, Pleurocybella, Sarcomyxa, Tricholomopsis and Typhula.

Lichens are one of the most iconic and ubiquitous symbioses known, widely valued as indicators of environmental quality and, more recently, climate change. Our understanding of lichen responses to climate has greatly expanded in recent decades, but some biases and constraints have shaped our present knowledge. In this review we focus on lichen ecophysiology as a key to predicting responses to present and future climates, highlighting recent advances and remaining challenges. Lichen ecophysiology is best understood through complementary whole-thallus and within-thallus scales. Water content and form (vapor or liquid) are central to whole-thallus perspectives, making vapor pressure differential (VPD) a particularly informative environmental driver. Responses to water content are further modulated by photobiont physiology and wholethallus phenotype, providing clear links to a functional trait framework. However, this thallus-level perspective is incomplete without also considering within-thallus dynamics, such as changing proportions or even identities of symbionts in response to climate, nutrients, and other stressors. These changes provide pathways for acclimation, but their understanding is currently limited by large gaps in our understanding of carbon allocation and symbiont turnover in lichens. Lastly, the study of lichen physiology has mainly prioritized larger lichens at high latitudes, producing valuable insights but underrepresenting the range of lichenized lineages and ecologies. Key areas for future work include improving geographic and phylogenetic coverage, greater emphasis on VPD as a climatic factor, advances in the study of carbon allocation and symbiont turnover, and the incorporation of physiological theory and functional traits in our predictive models.
