title: Two independent genetic markers support separation of the myxomycete <i>Lycogala epidendrum</i> into numerous biological species

description: <i>Lycogala epidendrum</i> is one of the most widely known myxomycete species and the first-ever discovered representative of this group. Using 687 original DNA sequences from 330 herbarium specimens from Europe, Asia, North and Central America, and Australia, we constructed the first detailed phylogenies of the genus <i>Lycogala</i>, based on two independently inherited genetic markers, the ribosome small subunit 18S rRNA nuclear gene (18S rDNA) and the mitochondrial cytochrome oxidase subunit I gene (COI). In both phylogenies, <i>L. epidendrum</i> appeared to be a polyphyletic group, represented by numerous clades. The four other recognized species of the genus (<i>L. confusum, L. conicum, L. exiguum</i>, and <i>L. flavofuscum</i>) are scattered between branches corresponding to <i>L. epidendrum</i>. A barcode gap analysis revealed 60 18S rDNA phylogroups of <i>L. epidendrum</i>, which are distant from each other not less than from other species of the genus <i>Lycogala</i>. For 18 of these phylogroups with both 18S rDNA and COI sequences available, recombination patterns were analyzed to test for reproductive isolation. In contrast to the results of a simulation assuming panmixis, no crossing between ribosomal and mitochondrial phylogroups was found, thus allowing the conclusion that all tested phylogroups represent biospecies. More than one third (39.6%) of the studied specimens share a single 18S rDNA phylogroup, which we consider to be <i>L. epidendrum</i> s. str. This group displays the broadest geographic distribution and the highest intraspecific genetic variability. Nearly all (93.3%) of the remaining non-singleton 18S rDNA phylogroups are restricted to certain continents or even regions. At the same time, various reproductively isolated phylogroups occur sympatric at a given location.

title: Along the footpath of <i>Penicillium</i> discovery: Six new species from the Woodville Big Tree Forest Trail

description: In this study, we studied the diversity of <i>Penicillium</i> occurring in soil collected along the Woodville Big Tree Forest Trail situated close to the coastal town of Wilderness in South Africa. Strains were accessioned into a collection and then identified to species based on β-tubulin DNA sequences, which is the recommended DNA barcode for the genus. The 74 strains were found to represent 18 species, including six we consider undescribed. Here, we introduce them as <i>Penicillium claroviride, P. kalander, P. mattheeae, P. outeniquaense, P. subfuscum</i>, and <i>P. umkhoba</i>. Phylogenetic comparisons were made, and genealogical concordance was demonstrated for these new species using DNA sequences from nuc rDNA internal transcribed spacer region ITS1-5.8S-ITS2 (ITS barcode), β-tubulin, calmodulin, and RNA polymerase II second largest subunit. Notes on morphological characters distinguishing the new species from their close relatives are provided.

title: Neotropical <i>Clavulina</i>: Two new species from Mexico and a re-evaluation of <i>Clavulina floridana</i>

description: <i>Clavulina</i> comprises ca. 90 described species distributed worldwide in both tropical and temperate regions. However, only one species (<i>C. floridana</i>) has been described so far from tropical North America. We used morphological and molecular data from three DNA loci (nuc rDNA internal transcribed spacer region ITS1-5.8S-ITS2 [ITS], a portion of nuc 28S rDNA [28S], and a fragment of DNA-directed RNA polymerase II second largest subunit [<i>RPB2</i>]) from basidiomata and ectomycorrhizas collected in tropical ecosystems from three biogeographic provinces of Mexico and one tropical province in the USA to investigate the phylogenetic and taxonomic diversity of <i>Clavulina</i> in the region. Nine new species-level clades were discovered, two of which are proposed as new species (<i>C. arboreiparva</i> and <i>C. tuxtlasana</i>). Specimens of <i>C. floridana</i> recently collected in Florida were included in our analyses, for which a modern description is provided. In addition, <i>C. floridana</i> is a new record for Mexico. The diversity of <i>Clavulina</i> in tropical North America is comparable to that found in lowland tropical South America. However, some of the species found in tropical deciduous forests produce small, rare, and inconspicuous basidiomata, which easily go unnoticed, and therefore are poorly represented in collections. Many species remain undescribed in tropical regions of North America.

title: New reports, new species, and high diversity of <i>Cantharellus</i> in the southern Appalachians

description: Chanterelles (genus <i>Cantharellus</i>) are among the most popular wild edible mushrooms worldwide. Efforts to understand chanterelle diversity have yielded numerous new species in recent years, particularly in eastern North America. We constructed a multilocus phylogeny including all described temperate species of <i>Cantharellus</i> and newly collected specimens from the eastern United States with an emphasis on southern Appalachia. We describe a new species, <i>Cantharellus vicinus</i>, an oak-associated chanterelle known only from lower-elevation areas in east Tennessee, based on phylogenetic and morphological data. <i>Cantharellus vicinus</i> is characterized by a compact stature, bright yellow hymenophore that turns salmon when mature, white stipe, and pale yellow pileus with a whitish bloom. The southeastern <i>Cantharellus minor</i> f. <i>intensissimus</i> is elevated to species level based on morphological and molecular evidence. The taxon is epitypified due to the sterile state of the holotype and ambiguity concerning application of the name. Evaluation of genetic diversity and gene conflict within <i>Cantharellus camphoratus</i> shows that it is a widespread species with populations in Atlantic Canada, the southeastern United States, and Japan. Similarly, <i>C. cibarius</i> and <i>C. tenuithrix</i> form complexes and may be more geographically widespread than previously thought. Additionally, we report the first known instances of <i>Cantharellus betularum, C. corallinus</i>, and <i>C. altipes</i> from the southern Appalachian Mountains.

title: Revising the taxonomic placement of <i>Laetiporus persicinus</i> within the Laetiporaceae

description: The fungus currently known as <i>Laetiporus persicinus</i> is a recognizable brown-rot decayer that is widespread on oak hosts in the southeastern United States. This species was first described as <i>Polyporus persicinus</i> in 1872 based on collections by Henry W. Ravenel from South Carolina. In this study, we elucidate the phylogenetic relationships of <i>Laetiporus persicinus</i> based on maximum likelihood and Bayesian inference analyses of a four-locus data set (18S, 28S, <i>rpb2</i>, and <i>tef1</i>) from taxa within the Fomitopsidaceae and Laetiporaceae. The internal transcribed spacer (ITS) region was analyzed separately because it was not possible to align this locus across a diverse data set that included taxa from multiple families. Our analysis and previous studies indicate that <i>Laetiporus persicinus</i> does not belong to <i>Laetiporus</i> sensu stricto, and we found a strongly supported relationship between <i>Laetiporus persicinus</i> and the African species <i>Kusaghiporia usambarensis</i>, despite the fact that the 28S phylogeny resolved a different (but unsupported) topology. Here, we propose <i>Kusaghiporia persicinus</i>, comb. nov., based on a combination of morphological and molecular data. <i>Laetiporus persicinus</i> shares many morphological features with <i>K. usambarensis</i> that are missing in other <i>Laetiporus</i> species, including centrally stipitate basidiomata, a brown to pinkish pileus surface, and a pore layer that bruises when touched. However, <i>K. usambarensis</i> and <i>L. persicinus</i> differ in basidiospore size and shape as well as their geographic distributions. We provide a revised taxonomic treatment for this common wood-decay fungus.

title: Russulaceae of the Pakaraima Mountains of Guyana. IV. New species forming a distinct lineage of <i>Lactarius</i> subg. <i>Plinthogalus</i>

description: The Neotropics have recently emerged as an important region for studies of tropical ectomycorrhizal (ECM) fungi. Specific neotropical areas with high ECM host tree densities have ECM fungal diversities rivaling those of higher-latitude forests. Some forests of the Guiana Shield are dominated by endemic ECM trees of the Fabaceae, including species of <i>Dicymbe</i> (subfam. Detarioideae), <i>Aldina</i> (subfam. Papilionoideae), and <i>Pakaraimaea</i> (Cistaceae). One of the most species-rich ECM fungal families present in each of these systems is Russulaceae. Long-term sampling in forests in Guyana’s Pakaraima Mountains has revealed a number of species of the Russulaceae genera <i>Lactarius, Lactifluus</i>, and <i>Russula</i>. In this study, we document a previously unknown, distinct lineage of <i>Lactarius</i> subg. <i>Plinthogalus</i> containing eight species from the Guiana Shield. Here, we describe five of these species from Guyana as new to science: <i>Lactarius humiphilus, Lactarius mycenoides, Lactarius guyanensis, Lactarius dicymbophilus</i>, and <i>Lactarius aurantiolamellatus</i>. Morphological descriptions, habit, habitat, and known distribution are provided for each new species. Sequence data for the barcode internal transcribed spacer (ITS) locus are provided for types and most other collections of the new taxa, and a molecular phylogenetic analysis based on the ITS, 28S, and <i>RPB2</i> (second-largest subunit of the RNA polymerase II) loci across the genus <i>Lactarius</i> corroborates their morphology-based infrageneric placement. The discovery of this lineage changes our insights into the biogeography and evolutionary history of <i>Lactarius</i> subg. <i>Plinthogalus</i>.

title: Multilocus molecular phylogenetic-led discovery and formal recognition of four novel root-colonizing <i>Fusarium</i> species from northern Kazakhstan and the phylogenetically divergent <i>Fusarium steppicola</i> lineage

description: In this study, DNA sequence data were used to characterize 290 <i>Fusarium</i> strains isolated during a survey of root-colonizing endophytic fungi of agricultural and nonagricultural plants in northern Kazakhstan. The <i>Fusarium</i> collection was screened for species identity using partial translation elongation factor 1-α (<i>TEF1</i>) gene sequences. Altogether, 16 different <i>Fusarium</i> species were identified, including eight known and four novel species, as well as the discovery of the phylogenetically divergent <i>F. steppicola</i> lineage. Isolates of the four putatively novel fusaria were further analyzed phylogenetically with a multilocus data set comprising partial sequences of <i>TEF1</i>, RNA polymerase II largest (<i>RPB1</i>) and second-largest (<i>RPB2</i>) subunits, and calmodulin (<i>CaM</i>) to assess their genealogical exclusivity. Based on the molecular phylogenetic and comprehensive morphological analyses, four new species are formally described herein: <i>F. campestre, F. kazakhstanicum, F. rhizicola</i>, and <i>F. steppicola</i>.
