ISSN (print) 0093-4666 © 2012. Mycotaxon, Ltd. ISSN (online) 2154-8889 MYCOTAXON http://dx.doi.org/10.5248/121.393 Volume 121, pp. 393–403 July–September 2012 Laccariopsis, a new genus for Hydropus mediterraneus (Basidiomycota, Agaricales) Alfredo Vizzini*, Enrico Ercole & Samuele Voyron Dipartimento di Scienze della Vita e Biologia dei Sistemi - Università degli Studi di Torino, Viale Mattioli 25, I-10125, Torino, Italy *Correspondence to: [email protected] Abstract — Laccariopsis (Agaricales) is a new monotypic genus established for Hydropus mediterraneus, an arenicolous species earlier often placed in Flammulina, Oudemansiella, or Xerula. Laccariopsis is morphologically close to these genera but distinguished by a unique combination of features: a Laccaria-like habit (distant, thick, subdecurrent lamellae), viscid pileus and upper stipe, glabrous stipe with a long pseudorhiza connecting with Ammophila and Juniperus roots and incorporating plant debris and sand particles, pileipellis consisting of a loose ixohymeniderm with slender pileocystidia, large and thin- to thick-walled spores and basidia, thin- to slightly thick-walled hymenial cystidia and caulocystidia, and monomitic stipe tissue. Phylogenetic analyses based on a combined ITS-LSU sequence dataset place Laccariopsis close to Gloiocephala and Rhizomarasmius. Key words — Agaricomycetes, Physalacriaceae, /gloiocephala clade, phylogeny, taxonomy Introduction Hydropus mediterraneus was originally described by Pacioni & Lalli (1985) based on collections from Mediterranean dune ecosystems in Central Italy, Sardinia, and Tunisia. Previous collections were misidentified as Laccaria maritima (Theodor.) Singer ex Huhtinen (Dal Savio 1984) due to their laccarioid habit. The generic attribution to Hydropus Kühner ex Singer by Pacioni & Lalli (1985) was due mainly to the presence of reddish watery droplets on young lamellae and sarcodimitic tissue in the stipe (Corner 1966, Singer 1982). -
Effects of Land Use on the Diversity of Macrofungi in Kereita Forest Kikuyu Escarpment, Kenya

Current Research in Environmental & Applied Mycology (Journal of Fungal Biology) 8(2), 254–281, Doi 10.5943/cream/8/2/10 Abstract Tropical forests are a haven of biodiversity hosting the richest macrofungi in the World. However, the rate of forest loss greatly exceeds the rate of species documentation and this increases the risk of losing macrofungi diversity to extinction. A field study was carried out in Kereita, Kikuyu Escarpment Forest, southern part of Aberdare range forest to determine effect of indigenous forest conversion to plantation forest on diversity of macrofungi. Macrofungi diversity was assessed in a 22 year old Pinus patula (Pine) plantation and a pristine indigenous forest during dry (short rains, December, 2014) and wet (long rains, May, 2015) seasons. -

Hebelomina (Agaricales) Revisited and Abandoned
Plant Ecology and Evolution 151 (1): 96–109, 2018 https://doi.org/10.5091/plecevo.2018.1361 REGULAR PAPER Hebelomina (Agaricales) revisited and abandoned Ursula Eberhardt1,*, Nicole Schütz1, Cornelia Krause1 & Henry J.

Since that time a further five species have been ascribed to the genus and one similar species within the genus Hebeloma. In total, we have studied seventeen collections that have been assigned to these seven species of Hebelomina. We provide a synopsis of the available knowledge on Hebelomina species and Hebelomina-like collections and their taxonomic placement. Methods – Hebelomina-like collections and type collections of Hebelomina species were examined morphologically and molecularly. Ribosomal RNA sequence data were used to clarify the taxonomic placement of species and collections. Key results – Hebelomina is shown to be polyphyletic and members belong to four different genera (Gymnopilus, Hebeloma, Tubaria and incertae sedis), all members of different families and clades. All but one of the species are pigment-deviant forms of normally brown-spored taxa. The type of the genus had been transferred to Hebeloma, and Vesterholt and co-workers proposed that Hebelomina be given status as a subsection of Hebeloma. -

Control of this disease is complex and nowadays, lies in the use of physical and chemical methods, although none have proven to be fully effective. Detailed understanding of the molecular mechanisms underlying white root rot disease has the potential of aiding future developments in disease resistance and management. -
Entrophospora Colombiana, Glomus Manihotis Y Burkholderia Cepacia EN EL CONTROL DE Rosellinia Bunodes, AGENTE CAUSANTE DE LA LLAGA NEGRA DEL CAFETO
Entrophospora colombiana, Glomus manihotis Y Burkholderia cepacia EN EL CONTROL DE Rosellinia bunodes, AGENTE CAUSANTE DE LA LLAGA NEGRA DEL CAFETO Ángela María Castro-Toro*; Carlos Alberto Rivillas-Osorio** RESUMEN CASTRO T., A.M.; RIVILLAS O., C.A. Entrophospora colombiana, Glomus manihotis y Burkholderia cepacia en el control de Rosellinia bunodes, agente causante de la llaga negra del cafeto. Cenicafé 53(3): 193-218. 2002. Se evaluó el efecto de las micorrizas arbusculares en el control de la llaga negra del cafeto en condiciones de invernadero dispuesto con polisombra, bajo un diseño completamente al azar al interior de tres grupos de plantas. Grupo 1 (agentes biocontroladores), grupo 2 (agentes biocontroladores con alta presión del patógeno) grupo 3 (agentes biocontroladores con baja presión del patógeno). Hubo mayor crecimiento de las plantas de café y valores más altos en los niveles de colonización en aquellos tratamientos donde se inoculó G. manihotis solo y en asociación con E. colombiana, con 42 y 43% de colonización radical, respectivamente. Luego de inoculado el patógeno, el promedio de colonización fue de 63% para G. manihotis + R. bunodes y 56% para la mezcla de las 2 MA + R. bunodes. E. colombiana y B. cepacia inoculadas individualmente estimularon el crecimiento de las plantas. La persistencia de la bacteria fue alta sola y asociada con las dos especies de MA y R. bunodes. No hubo diferencias entre tratamientos para la actividad metabólica del micelio de las MA, que mostró un rango de actividad hifal entre 60 y 77% en cada una de las especies evaluadas en los tres grupos de plantas evaluadas. -
A Taxonomic and Phylogenetic Investigation of Conifer Endophytes
A Taxonomic and Phylogenetic Investigation of Conifer Endophytes of Eastern Canada by Joey B. Tanney A thesis submitted to the Faculty of Graduate and Postdoctoral Affairs in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Biology Carleton University Ottawa, Ontario © 2016 Abstract Research interest in endophytic fungi has increased substantially, yet is the current research paradigm capable of addressing fundamental taxonomic questions? More than half of the ca. 30,000 endophyte sequences accessioned into GenBank are unidentified to the family rank and this disparity grows every year. The problems with identifying endophytes are a lack of taxonomically informative morphological characters in vitro and a paucity of relevant DNA reference sequences. A study involving ca. 2,600 Picea endophyte cultures from the Acadian Forest Region in Eastern Canada sought to address these taxonomic issues with a combined approach involving molecular methods, classical taxonomy, and field work. It was hypothesized that foliar endophytes have complex life histories involving saprotrophic reproductive stages associated with the host foliage, alternative host substrates, or alternate hosts. Based on inferences from phylogenetic data, new field collections or herbarium specimens were sought to connect unidentifiable endophytes with identifiable material. Approximately 40 endophytes were connected with identifiable material, which resulted in the description of four novel genera and 21 novel species and substantial progress in endophyte taxonomy. Endophytes were connected with saprotrophs and exhibited reproductive stages on non-foliar tissues or different hosts. These results provide support for the foraging ascomycete hypothesis, postulating that for some fungi endophytism is a secondary life history strategy that facilitates persistence and dispersal in the absence of a primary host. -

Stadler, [email protected] Abstract: Rosellinia (Xylariaceae) is a large, cosmopolitan genus comprising over 130 species that have been defined based mainly on the morphology of their sexual morphs. The genus comprises both lignicolous and saprotrophic species that are frequently isolated as endophytes from healthy host plants, and important plant pathogens. In order to evaluate the utility of molecular phylogeny and secondary metabolite profiling to achieve a better basis for their classification, a set of strains was selected for a multi-locus phylogeny inferred from a combination of the sequences of the internal transcribed spacer region (ITS), the large subunit (LSU) of the nuclear rDNA, beta-tubulin (TUB2) and the second largest subunit of the RNA polymerase II (RPB2). Concurrently, various strains were surveyed for production of secondary metabolites. -

A Taxonomic Investigation of Mycena in California
A TAXONOMIC INVESTIGATION OF MYCENA IN CALIFORNIA A thesis submitted to the faculty of San Francisco State University In partial fulfillment of The requirements For the degree Master of Arts In Biology: Ecology and Systematic Biology by Brian Andrew Perry San Francisco, California November, 2002 Copyright by Brian Andrew Perry 2002 A Taxonomic Investigation of Mycena in California Mycena is a very large, cosmopolitan genus with members described from temperate and tropical regions of both the Northern and Southern Hemispheres. Although several monographic treatments of the genus have been published over the past 100 years, the genus remains largely undocumented for many regions worldwide. This study represents the first comprehensive taxonomic investigation of Mycena species found within California. The goal of the present research is to provide a resource for the identification of Mycena species within the state, and thereby serve as a basis for further investigation of taxonomic, evolutionary, and ecological relationships within the genus. Complete macro- and microscopic descriptions of the species occurring in California have been compiled based upon examination of fresh material and preserved herbarium collections. The present work recognizes a total of 61 Mycena species occurring within California, sixteen of which are new reports, and 3 of which represent previously undescribed taxa. I certify that this abstract is a correct representation of the content of this thesis. Dr. Dennis E. Desjardin (Chair, Thesis Committee) Date ACKNOWLEDGEMENTS I am deeply indebted to Dr. Dennis E. Desjardin for the role he has played as a teacher, mentor, advisor, and friend during my time at SFSU and beyond.
