The Largest Type Study of <I>Agaricales</I
Persoonia 33, 2014: 98–140 www.ingentaconnect.com/content/nhn/pimj RESEARCH ARTICLE http://dx.doi.org/10.3767/003158514X684681 The largest type study of Agaricales species to date: bringing identification and nomenclature of Phlegmacium (Cortinarius) into the DNA era K. Liimatainen1, T. Niskanen1, B. Dima!, I. Kytövuori2, J.F. Ammirati3, T.G. Frøslev4 Key words Abstract Cortinarius is a species-rich and morphologically challenging genus with a cosmopolitan distribution. Many names have not been used consistently and in some instances the same species has been described two or Basidiomycota more times under separate names. This study focuses on subg. Phlegmacium as traditionally defined and includes diversity species from boreal and temperate areas of the northern hemisphere. Our goals for this project were to: i) study DNA barcoding type material to determine which species already have been described; ii) stabilize the use of Friesian and other ITS older names by choosing a neo- or epitype; iii) describe new species that were discovered during the process of taxonomy studying specimens; and iv) establish an accurate ITS barcoding database for Phlegmacium species. A total of 236 typification types representing 154 species were studied. Of these 114 species are described only once whereas 40 species had one ore more synonyms. Of the names studied only 61 were currently represented in GenBank. Neotypes are proposed for 21 species, and epitypes are designated for three species. In addition, 20 new species are described and six new combinations made. As a consequence ITS barcodes for 175 Cortinarius species are released.

An Updated Infrageneric Classification of the North American Oaks
Article An Updated Infrageneric Classification of the North American Oaks (Quercus Subgenus Quercus): Review of the Contribution of Phylogenomic Data to Biogeography and Species Diversity Paul S. Manos 1,* and Andrew L. Hipp 2 1 Department of Biology, Duke University, 330 Bio Sci Bldg, Durham, NC 27708, USA 2 The Morton Arboretum, Center for Tree Science, 4100 Illinois 53, Lisle, IL 60532, USA; [email protected] * Correspondence: [email protected] Abstract: The oak flora of North America north of Mexico is both phylogenetically diverse and species-rich, including 92 species placed in five sections of subgenus Quercus, the oak clade centered on the Americas. Despite phylogenetic and taxonomic progress on the genus over the past 45 years, classification of species at the subsectional level remains unchanged since the early treatments by WL Trelease, AA Camus, and CH Muller. In recent work, we used a RAD-seq based phylogeny including 250 species sampled from throughout the Americas and Eurasia to reconstruct the timing and biogeography of the North American oak radiation. This work demonstrates that the North American oak flora comprises mostly regional species radiations with limited phylogenetic affinities to Mexican clades, and two sister group connections to Eurasia. Using this framework, we describe the regional patterns of oak diversity within North America and formally classify 62 species into nine major North American subsections within sections Lobatae (the red oaks) and Quercus (the Citation: Manos, P.S.; Hipp, A.L. An Quercus Updated Infrageneric Classification white oaks), the two largest sections of subgenus . We also distill emerging evolutionary and of the North American Oaks (Quercus biogeographic patterns based on the impact of phylogenomic data on the systematics of multiple Subgenus Quercus): Review of the species complexes and instances of hybridization. -

Plants of Hot Springs Valley and Grover Hot Springs State Park Alpine County, California
Plants of Hot Springs Valley and Grover Hot Springs State Park Alpine County, California Compiled by Tim Messick and Ellen Dean This is a checklist of vascular plants that occur in Hot Springs Valley, including most of Grover Hot Springs State Park, in Alpine County, California. Approximately 310 taxa (distinct species, subspecies, and varieties) have been found in this area. How to Use this List Plants are listed alphabetically, by family, within major groups, according to their scientific names. This is standard practice for plant lists, but isn’t the most user-friendly for people who haven’t made a study of plant taxonomy. Identifying species in some of the larger families (e.g. the Sunflowers, Grasses, and Sedges) can become very technical, requiring examination of many plant characteristics under high magnification. But not to despair—many genera and even species of plants in this list become easy to recognize in the field with only a modest level of study or help from knowledgeable friends. Persistence will be rewarded with wonder at the diversity of plant life around us. Those wishing to pursue plant identification a bit further are encouraged to explore books on plants of the Sierra Nevada, and visit CalPhotos (calphotos.berkeley.edu), the Jepson eFlora (ucjeps.berkeley.edu/eflora), and CalFlora (www.calflora.org). The California Native Plant Society (www.cnps.org) promotes conservation of plants and their habitats throughout California and is a great resource for learning and for connecting with other native plant enthusiasts. The Nevada Native Plant Society nvnps.org( ) provides a similar focus on native plants of Nevada. -

Brashares, Co-Chair Professor Stephanie M. Carlson, Co-Chair Human populations are growing and exert an increasing pressure on remaining wild habitats. Development and encroachment into wild habitats often create a wildland-urban interface. Understanding how and which species are able to persist or even flourish in these shared habitats, is important for conservation purposes and reducing human-wildlife conflict. Human- wildlife conflict may be of particular concern when it involves larger carnivores. -
