title: A field-based investigation of simple phenol variation in Australian <i>Agaricus xanthodermus</i>

description: <i>Agaricus xanthodermus</i> and other species of the yellow-staining section <i>Xanthodermatei</i> are responsible for mushroom-related poisoning cases that require treatment. However, longstanding anecdotal evidence indicates that this species appears to exhibit considerable variation in toxicity, resulting in gastrointestinal irritation of varying severity in most cases. We quantified the amount of phenol, hydroquinone, and catechol in mushrooms using a novel protocol for gas chromatography–mass spectrometry (GC-MS) and investigated their levels in different basidiomatal structures, different developmental stages, and on different nutritional substrates. Phenol concentration was greater in the pileus than the stipe, in mature compared with immature basidiomata, and in basidiomata occurring in woody mulch versus lawns. Variation in toxicity is suggested to be due in part to variation in phenol concentration, developmental stage and tissue type consumed, and substrate. Variation in human sensitivity to simple phenols may also play a role but was not formally investigated in this study.

title: <i>Verrucoccum</i> (Dothideomycetes, Dictyosporiaceae), a new genus of lichenicolous fungi on <i>Lobaria</i> s. lat. for the <i>Dothidea hymeniicola</i> species complex

description: Two lichenicolous fungi, one growing on the thallus of <i>Lobaria pulmonaria</i> in the United Kingdom (Scotland) and the other in apothecia of <i>Lobaria linita</i> and <i>L. oregana</i> in northwestern North America (Alaska and British Columbia) and northeast Asia (Russian Far East, Khabarovsk Krai), show similarities to the species originally described as <i>Dothidea hymeniicola</i> (later transferred to <i>Polycoccum</i> s. lat and <i>Endococcus</i>) from a <i>Lobaria</i> s. lat. species in Central America. Critical morphological comparison showed that, despite the superficial resemblance between Alaskan, Canadian, Russian, and Scottish collections and the holotype of <i>Dothidea hymeniicola</i>, they can be distinguished by detailed microscopic analyses. Using three molecular markers, sequences of the nuc 18S, 28S, and internal transcribed spacer (ITS) rDNA regions of the recent Scottish and Alaskan collections were obtained. Phylogenetic analyses confirmed separation of the species and revealed them as a new lineage in Pleosporales, for which the new generic name <i>Verrucoccum</i> is introduced for the three species: <i>V. coppinsii</i>, sp. nov., <i>V. hymeniicola</i>, comb. nov. (syn. <i>Dothidea hymeniicola</i>), and <i>V. spribillei</i>, sp. nov.

title: Species and genera in Aleurodiscus sensu lato as viewed from the Southern Hemisphere

description: Phylogenetic relationships of 12 species in <i>Aleurodiscus</i> sensu lato (Stereaceae, Russulales) described from the Patagonian forests of Chile and Argentina were investigated based on sequences of nuc rDNA internal transcribed spacer region ITS1-5.8S-ITS2 (ITS) and the D1–D2 domains of nuc 28S rDNA (28S). A new genus and a new species are presented, and 10 new combinations proposed. The genus <i>Gloeosoma</i> is shown to be phylogenetically well supported and morphologically circumscribed; it includes <i>G. vitellinum</i> (type species), <i>G. mirabile</i>, comb. nov., <i>G. zealandicum</i>, comb. nov., and <i>Gloeosoma decorticans</i>, sp. nov., which is newly described from Chile. The new genus <i>Stereodiscus</i> is proposed to accommodate a group of taxa characterized by an austral distribution and morphologically by smooth, thin-walled, amyloid basidiospores and a lack of gloeocystidia and acanthocystidia; three species develop <i>Stereum</i>-like basidiomata and two species present discoid ones. The new genus includes the species formerly known as <i>Aleurodiscus antarcticus, A. limonisporus, A. parmuliformis, A. patagonicus</i>, and <i>A. triviale</i>. Specimens of <i>Stereodiscus parmuliformis</i> (<i>A. parmuliformis</i>) from New Zealand (where it was originally described) and southern Chile are shown to be phylogenetically conspecific, which confirms its presence in Patagonia. <i>Gloeosoma</i> and <i>Stereodiscus</i> are shown to be distantly related to <i>Aleurodiscus</i> s. str. and other genera in Stereaceae. The new combinations <i>Aleurocystidiellum bernicchiae, Aleurocystidiellum hallenbergii</i>, and <i>Acanthobasidium quilae</i> are proposed based on morphology and phylogenetic analyses, and <i>Aleurodiscus cerussatus</i> is shown to be a cryptic species complex.

title: Expanding the <i>Trichoderma harzianum</i> species complex: Three new species from Argentine natural and cultivated ecosystems

description: A study was performed on a collection of 84 isolates from decaying plant tissues and soils in Argentina previously identified as <i>Trichoderma harzianum</i>. Based on multiple phenotypic characters and multilocus phylogenetic analyses, 10 species were distinguished, three of which are described as new species: <i>T. austroindianum, T. hortense</i>, and <i>T. syagri</i>. Among the remaining seven identified species, the following five can be added to the Argentine mycobiota: <i>T. afarasin, T. afroharzianum, T. endophyticum, T. guizhouense</i>, and <i>T. neotropicale. Trichoderma afroharzianum</i> and <i>T. endophyticum</i> were the most frequent species found in the samples. In addition, a collection of isolates previously identified as <i>T. harzianum</i> with antagonistic abilities were reidentified as <i>T. afroharzianum</i>, thus highlighting the importance of correct identification of biocontrol species.

title: Seasonal variation and potential roles of dark septate fungi in an arid grassland

description: High temperatures and extended drought in temperate and tropical arid ecosystems promote the colonization of diverse microenvironments by dark septate fungi (DSF). These fungi contribute to soil nutrient cycling, soil stabilization, and plant survival, but the roles of individual DSF species, their distributions, and their community diversity are poorly understood. The objective of this study was to evaluate the distribution, seasonal variation, and potential roles of DSF on plant growth. We collected biocrust (lichen-, moss-, and cyanobacterium-dominated biocrusts) soils at different depths and rhizosphere soils from two grasses, <i>Bromus tectorum</i> and <i>Pleuraphis jamesii</i>, in an arid grassland near Moab, Utah, USA. Seasonal variation of DSF was evaluated using culture-based approaches and compared with fungal community profiles from next-generation sequencing (NGS). Culturing showed that DSF were 30% more abundant in biocrusts compared with the focal rhizospheres. The abundance of DSF varied seasonally in belowground samples (rhizosphere and below-biocrust), with a significant increase during the summer months. Pleosporales was the dominant order (35%) in both biocrust and rhizosphere soils out of 817 isolated fungi. Dominant DSF genera in culture included <i>Alternaria, Preussia, Cladosporium, Phoma</i>, and an unknown Pleosporales. Similar results were observed in biocrust and rhizosphere soils NGS. Further, seed germination experiments using dominant taxa were conducted to determine their potential roles on germination and seedling growth using maize as a model plant. <i>Cladosporium</i> and unknown Pleosporales isolates showed plant growth–promoting ability. The variation in abundance of DSF, their differential occurrence in different microenvironments, and their ability to grow in a xerotolerant medium reflect adaptations to summer environmental conditions and to changes in the abundance of organic matter, as well as a potential increase in plant investment in these fungi when heat and drought stresses are more severe.

title: Eight Mile Lake Research Watershed, Carbon in Permafrost Experimental Heating Research (CiPEHR): physical and chemical properties of soils, 2009-2013

description: The Carbon in Permafrost Experimental Heating Research (CiPEHR) project addresses the following questions: 1) Does ecosystem warming cause a net release of C from the ecosystem to the atmosphere?, 2) Does the decomposition of old C, that comprises the bulk of the soil C pool, influence ecosystem C loss?, and 3) How do winter and summer warming alone, and in combination, affect ecosystem C exchange? We are answering these questions using a combination of field and laboratory experiments to measure ecosystem carbon balance and radiocarbon isotope ratios at a warming experiment located in an upland tundra field site near Healy, Alaska in the foothills of the Alaska Range. This data set includes measurements of moisture, bulk density, ash, carbon, and nitrogen concentrations, and carbon and nitrogen stable isotope composition (?13C and ?15N) at depth increments in soil cores collected in 2009, 2010, 2011, and 2013 from warming and control treatment plots.

title: Eight Mile Lake Research Watershed, Carbon in Permafrost Experimental Heating and Drying Research (DryPEHR): Peak growing season aboveground biomass 2011-2017.

description: This drying and warming experiment addresses the following questions: 1) Does ecosystem drying, warming and permafrost thaw cause a net release or uptake of C from the ecosystem to the atmosphere?, 2) Does the decomposition of old C that comprises the bulk of the soil C pool influence ecosystem C loss? 3) How do drying and warmign affect plant communities and ecosystem properties? We are answering these questions using a combined warming and drying experiment (DryPEHR), which is situated with the Carbon in Permafrost Experimental Heating Research (CiPEHR) project and located in an upland tundra field site near Healy, Alaska in the foothills of the Alaska Range. Warming treatment here refers to growing season air temperature warming (~1C) using open top chambers (OTC) combined with soil 'warming' using snow fences during the snow covered months. Drying is achieve using an automated pumping system that lowers the water table in the dry plots. Soil warming began in 2008; OTCs and drying in 2011. Above ground plant biomass was surveyed non-destructively using a point-intercept method for all vascular and moss species at peak growing season.
