However, species diversity of Leucoagaricus in Asia remains poorlyknown, especially in the mountains of southwestern China, a hot spot for biodiversity. Based on morphological characters and moleculardata, four new species are described, La. asiaticus, La. subcrystallifer, La. subpurpureolilacinus and La. truncatus. Detailed morphologicaldescriptions, drawings of microstructures for novel taxa and comparisons with closely allied taxa are provided. Phylogenetic analysesinferred from internal transcribed spacer (ITS) and region 6-7 of the gene for the second largest subunit of RNA polymerase II (rpb2)sequences show that the novel taxa are nested within a well-supported clade jointly formed by members of Leucoagaricus sectionRubrotincti and subgenus Sericeomyces.Leucoagaricus4http://www.mycologia.org/content/early/2015/06/26/14-351.abstractURLDaikinrin Daily Document AlertD AlertCreated byAtsushi Nakajima (@Ats_Nakajima)CC BY 4.0#17- the latest mycological papers from Google ScholarSearch DateKeywords(auto-indexed)Related taxa (extracted from title and abstract/summary)Abstract/SummaryBibliographic informationComment (brief comment in Japanese)20150811-2Revisiting the morphology and phylogeny of Lactifluus with three new lineages fromsouthern ChinaX Wang, B Buyck, A Verbeken, K Hansen - Mycologia, 2015 - Mycol Soc America/Russulaceae, /China, /new species2015/08/11Abstract As a recent group mainly defined by molecular data the genus Lactifluus is in need of further study to provide insight into themorphological and molecular variation within the genus, species limits and relationships. Phylogenetic analyses of nuc rDNA ITS1-5.8S-ITS2(ITS), D1 and D2 domains of nuc 28S rDNA (28S), and part of the second largest subunit of the RNA polymerase II (rpb2) (6-7 region)sequences of 28 samples from southern China revealed three new lineages of Lactifluus. Two of them are nested in a major clade thatincludes the type of Lactifluus and here is treated as two new sections: L. sect. Ambicystidiati and L. sect. Tenuicystidiati. Lactifluusambicystidiatus, described here as a new species (= sect. Ambicystidiati), has both lamprocystidia and macrocystidia in the hymenium, aunique combination of features within Russulaceae. Furthermore, only remnants of lactiferous hyphae are present in L. ambicystidiatus andour results suggest that the ability to form a lactiferous system has been lost in this lineage. Lactifluus sect. Tenuicystidiati forms a stronglysupported monophyletic group as a sister lineage to L. sect. Lactifluus. We recognize it based on the thin-walled macrocystidia and smallerellipsoid spores with an incomplete reticulum compared with L. sect. Lactifluus. The former placement of L. tenuicystidiatus in the African L.sect. Pseudogymnocarpi is not supported. Using genealogical concordance we recognize five phylogenetic species within L. sect.Tenuicystidiati and describe two of these as new, L. subpruinosus and L. tropicosinicus. The third lineage, represented by L. leoninus, formsa sister group to L. subg. Lactariopsis sensu stricto. The three lineages provide further evidence for morphological features in Lactifluusbeing homoplasious. Some sections and species complexes are likely to be composed of more species and merit further investigations.Lactifluus3http://www.mycologia.org/content/early/2015/06/26/13-393.abstractURLDaikinrin Daily Document AlertD AlertCreated byAtsushi Nakajima (@Ats_Nakajima)CC BY 4.0#17- the latest mycological papers from Google ScholarSearch DateKeywords(auto-indexed)Related taxa (extracted from title and abstract/summary)Abstract/SummaryBibliographic informationComment (brief comment in Japanese)20150811-3Perichaena longipes, a new myxomycete from the NeotropicsLM Walker, D Leontyev, SL Stephenson - Mycologia, 2015 - Mycol Soc America/Costa Rica, /Panama, /Brazil, /new species2015/08/11Abstract A new species of myxomycete, Perichaena longipes, is described from 56 specimens of fruiting bodies that appeared in moistchamber cultures prepared with samples of decaying plant materials collected in Panama, Costa Rica and Brazil. This new species isdistinguished from the morphologically similar species P. pedata on the basis of the much longer stipe, lighter peridium and the uniqueornamentation of the capillitium. The nuc 18S ribosomal DNA sequences obtained from four specimens of P. longipes support the distinctionof this new taxon and its separation from P. pedata. Furthermore, maximum likelihood phylogeny supports earlier evidence that speciescurrently within the genus Perichaena do not form a monophyletic clade. Instead they appear to form three separate branches within thebright-spored clade. The first clade includes P. longipes together with several species of Trichia and Metatrichia, the second includes P.pedata and P. chrysosperma, and the third clade is composed of P. corticalis, P. depressa and P. luteola.Perichaena longipeshttp://www.mycologia.org/content/early/2015/06/26/14-330.abstractURLDaikinrin Daily Document AlertD AlertCreated byAtsushi Nakajima (@Ats_Nakajima)CC BY 4.0#17- the latest mycological papers from Google ScholarSearch DateKeywords(auto-indexed)Related taxa (extracted from title and abstract/summary)Abstract/SummaryBibliographic informationComment (brief comment in Japanese)20150811-4A critical revision of the Tubifera ferruginosa complexD Leontyev, M Schnittler, SL Stephenson - Mycologia, 2015 - Mycol Soc America/species complex, /ultrastructure2015/08/11Abstract Based on a combination of morphological and molecular investigations, a critical revision of the widely distributed myxomyceteTubifera ferruginosa is presented. A phylogeny of the morphospecies, based on partial 18S nuc rDNA sequences, displays several clearlydistinct clades, all differing by a genetic distance (p distance) of at least 0.15, with the distance within the clades below 0.11. Thesemolecular differences correlate with morphological characters, such as the shape of sporothecal tips, the color of immature fructificationsand the ultrastructure of the inner surface of the peridium. The combination of morphological and molecular data provides evidence that T.ferruginosa is actually a species complex, representing at least seven species. These are T. ferruginosa sensu stricto, T. applanata, T.corymbosa, T. dudkae, T. magna, T. montana and T. pseudomicrosperma. Among these T. applanata and T. dudkae (as Reticularia dudkae)were described recently based on morphological characters and the 18S nuc rDNA phylogeny confirmed their separation. Another fourspecies, T. corymbosa, T. magna, T. montana and T. pseudomicrosperma, are described here. We propose an epitype for T. ferruginosasensu stricto and recognize subsp. ferruginosa and subsp. acutissima within this species. All studied taxa of the T. ferruginosa complex areshown to lack a capillitium. Structures formerly described as capillitium represent the hyphae of fungi occurring within the fructifications.Tubifera ferruginosahttp://www.mycologia.org/content/early/2015/06/26/14-271.abstractURLDaikinrin Daily Document AlertD AlertCreated byAtsushi Nakajima (@Ats_Nakajima)CC BY 4.0#17- the latest mycological papers from Google ScholarSearch DateKeywords(auto-indexed)Related taxa (extracted from title and abstract/summary)Abstract/SummaryBibliographic informationComment (brief comment in Japanese)20150811-5Ceratocystis tiliae sp. nov., a wound pathogen on Tilia americanaL Oliveira, TC Harrington, R Freitas, D McNew - , 2015 - Mycol Soc America/Iowa, /Quercus, /Tilia, /Nebraska2015/08/11Abstract Species in the North American clade (NAC) of the Ceratocystis fimbriata complex are mostly weak pathogens that infect native treehosts through fresh wounds. Isolations from discolored tissue of wounded Tilia americana (basswood) in Iowa and Nebraska yielded aCeratocystis species that was similar to but distinct from isolates of C. variospora from other hosts. Sequences of 28S rDNA showed thatisolates from basswood did not differ from C. variospora, but there were minor differences in ITS rDNA sequences. The DNA sequences of aportion of the Cerato-platanin gene and TEF1 showed the basswood fungus to be a unique lineage. Cross inoculations in two experimentsshowed that the basswood isolates and C. variospora isolates from Quercus spp. were most aggressive to their respective hosts. Isolatesfrom basswood grew slower and were less pigmented than C. variospora isolates from Quercus spp. The basswood fungus thus isdistinguished from C. variospora based on phylogenetic analyses and phenotype and is herein described as C. tiliae sp. nov.Tilia americanaCeratocystis tiliaehttp://www.mycologia.org/content/early/2015/06/26/14-273.abstractURLDaikinrin Daily Document AlertD AlertCreated byAtsushi Nakajima (@Ats_Nakajima)CC BY 4.0#17- the latest mycological papers from Google ScholarSearch DateKeywords(auto-indexed)Related taxa (extracted from title and abstract/summary)Abstract/SummaryBibliographic informationComment (brief comment in Japanese)20150811-6Umbelopsis longicollis comb. nov. and the synonymy of U. roseonana and U.versiformis with U. nanaYN Wang, XY Liu, RY Zheng - Mycologia, 2015 - Mycol Soc America/new combination2015/08/11Abstract Based on maximum growth temperatures, morphological characteristics and multilocus phylogenies (partial 18S and 28S, internaltranscribed spacer regions of nuc rDNA and a fragment of an actin gene), Umbelopsis roseonana and U. versiformis are treated asheterotypic synonyms of U. nana, while the phylogenetically closely related U. dimorpha is retained as a separate species.

DNA sequencing of cultures derived from these specimens using the nuclear ribosomal 28S (nrLSU) and nuclear ribosomal ITS1-5.8S-ITS2 regions (nrITS) showed that they were neither Lentinus nor Phyllotopsis and were not related to other pleurotoid generaHohenbuehelia and Pleurotus. Subsequent investigation showed that the Russian fungus was the same as Pleurotus vetlinianus describedfrom Poland.

Three species, originating from the western edge of the Guineo-Congolian rainforest inGabon (central Africa), are described as new. Phylloporia afrospathulata sp. nov. forms seasonal, stipitate, solitary basidiomata emergingfrom soil, more likely connected to buried roots, and has broadly ellipsoid basidiospores. Phylloporia inonotoides sp. nov. forms seasonalsessile, soft basidiomata, solitary at the base of small-stemmed trees including Crotonogyne manniana (Euphorbiaceae) and Garcinia cf.smeathmannii (Clusiaceae). It has a homogeneous context, large pores (2-3 mm), and oblong-ellipsoid to suballantoid basidiospores.Phylloporia fulva sp. nov. forms sessile, conchate, mostly pendant, gregarious basidiomata emerging from the trunk of an unidentifiedsmall-stemmed tree and has small, subglobose basidiospores. This species is compared to Polyporus pullus and Phylloporia pulla comb. nov.and proposed based on the study of the type specimen. Phylogenetic inferences using partial nuc 28S DNA sequence data (region includingthe D1/D2/D3 domains) and the most exhaustive dataset available to date resolved these new morphospecies as three distinct terminallineages.

The recent discovery of species ofPhytophthora in marine habitats and of Halophytophthora in freshwater indicated that these genera are not only morphologically but alsoecologically poorly delineated. In addition, half of these genera are not monophyletic. They play key ecological roles by upgrading nutrientsto higher trophic levels through colonization of plant debris, which makes substrata more palatable for detritivores or through zoosporegrazing by zooplankton, although their role as saprotrophs is still largely neglected. Some species of Phytophthora can be aggressiveopportunistic pathogens of riverine forests in the presence of susceptible hosts and favourable environmental conditions and, as aconsequence, most studies have focused on their role as pathogens. Identification of species is challenging due to hybridization and speciescomplexes that harbour multiple cryptic species and, therefore, is not reliable without DNA sequencing tools.http://www.sciencedirect.com/science/article/pii/S1754504815000811URLDaikinrin Daily Document AlertD AlertCreated byAtsushi Nakajima (@Ats_Nakajima)CC BY 4.0#17- the latest mycological papers from Google ScholarSearch DateKeywords(auto-indexed)Related taxa (extracted from title and abstract/summary)Abstract/SummaryBibliographic informationComment (brief comment in Japanese)20150811-11One hundred million year old ergot: psychotropic compounds in the Cretaceous?G POINAR JR, S ALDERMAN, J WUNDERLICH - palaeodiversity.org/Poaceae, /Myanmar, /amber, /Cretaceous, /sclerotium, /ergot2015/08/11A fungal sclerotium similar to those of the genus Claviceps, commonly known as ergot, was discovered infect-ing a grass floret in EarlymidCretaceous Myanmar amber.

Two species of Pseudocercospora from spots on living leaves of ferns(Polypodiales) in Taiwan are newly described. One species found on Microlepia spp. (Dennstaedtiaceae) differs from Ps. lonchitidis, thesingle other species considered as occurring on members of the Dennstaedtiaceae, by narrower conidiophores and conidia. Another speciesfound on Tectaria harlandii (Tectariaceae) differs from the majority of Pseudocercospora species by the internal hyphae which are oftenthick-walled and/or covered by conspicuous incrustations, and from the single other species known from the same host family, Ps.helminthostachydis, by narrower conidiophores and conidia. Mycosphaerella gleicheniae, Periconiella lygodii, Ps. lygodii, and Zasmidiumdicranopteridis are recorded for the first time from mainland China and Ps. pteridicola from Taiwan.
