Species of <i>Xerampelinae</i> are recognized by their fishy or shrimp odor, browning context, and a green reaction to iron sulfate. However, species delimitation has traditionally relied on morphology and analysis of limited molecular data. Prior taxonomic work in <i>Xerampelinae</i> has led to the description of as many as 59 taxa in Europe and 19 in North America. Here we provide the first multilocus phylogeny of European and North American members based on two nrDNA loci and two protein-coding genes. The resulting phylogeny supports the recognition of 17 species-rank <i>Xerampelinae</i> clades; however, higher species richness (~23) is suggested by a more inclusive nuclear rDNA internal transcribed spacer region ITS1-5.8S-ITS2 (ITS barcode) analysis. Phylogenetic and morphological analyses support three new species with restricted geographic distributions: <i>R. lapponica, R. neopascua</i>, and <i>R. olympiana</i>. We confirm that the European species <i>R. subrubens</i> is present in North America and the North American species <i>R. serissima</i> (previously known as <i>R. favrei</i>) is present in Europe. Most other <i>Xerampelinae</i> appear restricted to either North America or Eurasia, which indicates a high degree of regional endemism; this includes <i>R. xerampelina</i>, a name widely applied to North American taxa, but a species restricted to Eurasia.</p>","PeriodicalId":18779,"journal":{"name":"Mycologia","volume":" ","pages":"322-349"},"PeriodicalIF":2.8,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139741444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since 1913, <i>C. luteorostrata</i> has been reported from various plant feeding Hemiptera in the southeastern United States, but comprehensive morphological and phylogenetic studies of U.S. populations are lacking. The recovery of multiple strains of <i>C. luteorostrata</i> from mycosed EHS in North Carolina provided an opportunity to conduct pathogenicity assays and morphological and phylogenetic studies to investigate genus- and species-level boundaries among the Clavicipitaceae. Pathogenicity assays confirmed that <i>C. luteorostrata</i> causes mortality of EHS crawlers, an essential first step in developing this fungus as a biocontrol. Morphological studies revealed that conidia aligned with previous measurements of the <i>Paecilomyces</i>-like asexual state of <i>C. luteorostrata</i>, with conidiophore morphology consistent with historical observations. Additionally, a <i>Hirsutella</i>-like synanamorph was observed in select <i>C. luteorostrata</i> strains.

Due to the paucity of <i>RPB1</i> and <i>RPB2</i> sequence data, <i>EF1-α</i> provided superior delimitation of intraspecies groupings for <i>Conoideocrella</i> and should be used in future studies.

Some of them are considered as old-growth forest and/or long ecological continuity indicators. To evaluate general links between the narrow ecological range and physiological traits, two distinct sets of model lichens, i.e., old-growth forest (<i>Cetrelia cetrarioides</i> (Duby) W.L. Culb. & C.F. Culb., <i>Lobaria pulmonaria</i> (L.) Hoffm., <i>Menegazzia terebrata</i> (Hoffm.) A. Massal.), and generalist (<i>Flavoparmelia caperata</i> (L.) Hale, <i>Hypogymnia physodes</i> (L.) Nyl., <i>Parmelia sulcata</i> Taylor) ones, were examined in terms of sensitivity to long-term desiccation stress (1-, 2-, and 3-month) and photosynthesis activation rate upon rehydration. Desiccation tolerance and response rate to rehydration are specific to a given ecological set of lichens rather than to a particular species. Noticeable delayed and prompt recovery of high photosynthetic activity of photosystem II (PSII) characterize these sets, respectively. At the same time, although a decrease in the potential quantum yield of PSII in lichen thalli with a relative water content (RWC) at the level of 25% was observed, the efficiency remained at a very high level for all species, regardless of habitat preferences. Among the examined lichens, the fluorescence emission parameters for <i>F. caperata</i> were the fastest toward equilibrium upon rehydration, both after a shorter and a longer period of desiccation stress. In contrast to generalist lichens, retrieving of photosynthesis after 3-month desiccation failed in old-growth forest lichens. In the long term, prolonged rainless periods and unfavorable water balance in the environment predicted in the future may have a severely limiting effect on hygrophilous lichens during growing season (also in the sense of species associations) and, at the same time, promote the development of generalists.</p>","PeriodicalId":18779,"journal":{"name":"Mycologia","volume":" ","pages":"31-43"},"PeriodicalIF":2.8,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138470519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
