    Abstract AbstractNon-coding RNA (ncRNA) genes play important, but incompletely understood, roles in various cellular processes, notably translation and gene regulation. A recent report on the detection of the ncRNA Signal Recognition Particle gene in the nuclear ribosomal internal transcribed spacer region of several species of three genera of ectomycorrhizal basidiomycetes prompted a more thorough bioinformatics search for additional ncRNA genes in the full fungal ribosomal operon. This study reports on the detection of three ncRNA genes hitherto not known from the fungal ribosomal region: nuclear RNase P RNA, RNase MRP RNA, and a possible snoRNA U14 in a total of five species of Auricularia and Inocybe. We verified their presence through resequencing of independent specimens. Two completed Auricularia genomes were found to lack these ncRNAs elsewhere than in the ribosomal operon, suggesting that these are functional genes. It seems clear that ncRNA genes play a larger role in fungal ribosomal genetics than hitherto thought.

    Abstract Inocybe (Inocybaceae) is one of the most diverse ectomycorrhizal genera in arctic and alpine habitats where the primary hosts are Salix, Betula, and Dryas. Subgenus Inocybe is common in these habitats and typically characterized by the presence of thick-walled pleurocystidia. Here, we focus on species that have angular or nodulose spores. Historically, over 30 taxa from this group have been reported from arctic and alpine habitats. Many names have been synonymized, whereas molecular analysis has revealed new species. Nuc rDNA internal transcribed spacer ITS1-5.8S-ITS2 (ITS) sequence data of 26 type specimens in this group now allow for further taxonomic clarification and comparison across continents of disjunct populations. Here, we compare ITS sequence data and the D1–D2 portion of nuc 28S rDNA (28S) from Rocky Mountain specimens with those of types and European reference material. We report 10 species from the Rocky Mountain alpine zone, all of which are conspecific with known European boreal, montane, or alpine species, and four are described as new; all have intercontinental distributions. Nodulose-spored Inocybe taxa that occur in the Rocky Mountain alpine zone include I. alpinomarginata, sp. nov., I. arctica, I. giacomi, I. leonina, I. murina, sp. nov., I. occulta, I. paragiacomi, sp. nov., I. phaeocystidiosa, I. purpureobadia, and I. subgiacomi, sp. nov. Remarkably, these species occur at elevations up to 4000 m and at latitudes as low as 36°N, hundreds of miles from the Arctic, the European alpine, and original type localities. Distributions are explained in part by host distributions and historical glaciation patterns. A key and full descriptions for Rocky mountain species are provided to promote species recognition.

    Abstract Sequence data from a broad geographical region and different habitats show that the Inocybe praetervisa clade is comprised of four closely related species. These species of section Marginatae are characterized by having nodulose spores and a stipe that is abundantly pruinose only in the upper half. Inocybe praetervisa occurs in Southern Europe in mountainous mixed coniferous forests, and is not confirmed from Northern Europe. Inocybe rivularis occurs in northern boreal forests up to the lower alpine zone, associated with Betula in moist habitats, and is not confirmed from Southern Europe. Inocybe taxocystis is confirmed as a later synonym of I. favrei. The species has a wide geographical distribution range in Europe, mainly restricted to the alpine zone and moist soils, associated with Salix herbacea. Inocybe arctica is here described as a new species. It occurs in the arctic and higher alpine zones, associated with Dryas octopetala, Salix polaris, S. reticulata and S. herbacea. All species except I. arctica are shown to have an intercontinental distribution range and are confirmed from North America. Sequence data suggest the occurrence of one additional species in the alpine zone of China. A key to the species in the I. praetervisa group is provided.

    Abstract This study describes four gray or brown species of Cuphophyllus (Hygrophoraceae, Agaricales), two of them new species, restricted to arctic-alpine and northern boreal zones of North America, and relates them morphologically and phylogenetically using multigene and nuc rDNA internal transcribed spacer ITS1-5.8S-ITS (ITS barcode) analyses to their similar, known counterparts. Cuphophyllus cinerellus, epitypified here, is shown to be a pan-palearctic species with sequence-confirmed collections from Fennoscandia and easternmost Asia. Occupying a similar habitat in the Nearctic is its sister species, the morphologically similar but novel C. esteriae, so far known only from eastern North America, including Greenland. Sister to the C. cinerellus–C. esteriae lineage, and known only from boreal raised Sphagnum bogs in Newfoundland, is a new medium-sized light cinereous brown species, C. lamarum. It has a yellow stipe but is phylogenetically distant from the yellow-stiped European C. flavipes and its North American sister species, Hygrophorus pseudopallidus. As cryptic speciation was discovered within C. flavipes, we lecto- and epitypify the name and transfer H. pseudopallidus to Cuphophyllus based on ITS analysis of the holotype. We also transfer the small European Hygrocybe comosa to Cuphophyllus based on morphology. Cuphophyllus hygrocyboides is reported from North America with the first sequence-confirmed collections from arctic-alpine British Columbia and Greenland. In addition, sequencing the holotype of C. subviolaceus identifies it as the sister species to the putative C. lacmus. Both species seem to have an intercontinental distribution. In total, we add new sequences to GenBank from 37 Cuphophyllus collections, including the holotypes of C. hygrocyboides and C. subviolaceus, the two new epitypes, and the two novel species.

    Abstract DNA sequences from the nuclear LSU and ITS regions were used for phylogenetic analyses of Thelephorales with a focus on the stipitate hydnoid genera Hydnellum and Sarcodon. Analyses showed that Hydnellum and Sarcodon are distinct genera but that the current division, based on basidioma texture, makes Sarcodon paraphyletic with respect to Hydnellum. In order to make genera monophyletic several species are moved from Sarcodon to Hydnellum and the following new combinations are made: Hydnellum amygdaliolens, H. fennicum, H. fuligineoviolaceum, H. fuscoindicum, H. glaucopus, H. joeides, H. lepidum, H. lundellii, H. martioflavum, H. scabrosum, H. underwoodii, and H. versipelle. Basidiospore size seems to separate the genera in most cases. Hydnellum species have basidiospore lengths in the range 4.45−6.95 µm while the corresponding range for Sarcodon is 7.4−9 µm. S. quercinofibulatus deviates from this pattern with an average spore length around 6 µm. Neotropical Sarcodon species represent a separate evolutionary lineage.

    Abstract Based on traditional morphology, sequence data, and phylogenetic analyses, 18 new species are here described: Coprinellus christianopolitanus, Coprinopsis musae, C. udicola, Psathyrella arenosa, P. carminei, P. fennoscandica, P. ichnusae, P. lilliputana, P. lyckebodensis, P. madida, P. rybergii, P. sabuletorum, P. scanica, P. siccophila, P. stridvallii, P. sublatispora, P. vesterholtii, and Typhrasa nanispora. Psathyrella hololanigera and P. tenera are reported as new to Europe and P. parva as new to the Nordic countries. A four-gene dataset on Psathyrellaceae were analyzed by Maximum Parsimony, Maximum Likelihood, and Bayesian methods. Constraint analyses were performed to determine limits of /Psathyrella, and to evaluate whether the /Coprinellus, /cordisporus, and /gossypina clades could be regarded with confidence as monophyletic clades outside of the clade /Psathyrella. This was not unambiguously supported. Based on the phylogenetic results, Kauffmania is proposed as a monotypic genus for the species P. larga and Typhrasa for P. gossypina and the new described species T. nanispora. The genus Homophron is formally validated and three combinations are proposed: H. spadiceum, H. cernuum, and H. camptopodum. The genus Cystoagaricus Singer is emended and the following new combinations are proposed: C. hirtosquamulosus, C. squarrosiceps, C. olivaceogriseus, and C. silvestris. Neotypes have been selected for seven species described by Fries, and ITS sequence data for these were generated. The following new combinations are proposed: Coprinopsis canoceps, C. cineraria, C. melanthina, C. submicrospora, C. uliginicola, and Typhrasa gossypina. Brief comments are given to other species of interest. Psathyrella ornatispora were found not to belong in Psathyrellaceae. A key to 106 psathyrelloid species in Northern Europe is provided.
