Molecular Phylogenetic Studies in the Genus Amanita
1170 Molecular phylogenetic studies in the genus Amanita I5ichael Weiß, Zhu-Liang Yang, and Franz Oberwinkler Abstracl A group of 49 Amanita species that had been thoroughly examined morphologically and amtomically was analyzed by DNA sequence compadson to estimate natural groups and phylogenetic rclationships within the genus. Nuclear DNA sequences coding for a part of the ribosomal large subunit were determined and evaluated using neighbor-joining with bootstrap analysis, parsimony analysis, conditional clustering, and maximum likelihood methods, Sections Amanita, Caesarea, Vaginatae, Validae, Phalloideae, and Amidella were substantially confirmed as monophyletic groups, while the monophyly of section Lepidell.t remained unclear. Branching topologies between and within sections could also pafiially be derived. Stbgenera Amanita an'd Lepidella were not supported. The Mappae group was included in section Validae. Grouping hypotheses obtained by DNA analyses are discussed in relation to the distribution of morphological and anatomical chamcters in the studied species. Key words: fungi, basidiomycetes phylogeny, Agarrcales, Amanita systematics, large subunit rDNA, 28S. R6sum6 : A partir d'un groupe de 49 esp,ces d'Amanita prdalablement examinees morphologiquement et anatomiquement, les auteurs ont utilisd la comparaison des s€quences d'ADN pour ddfinir les groupes naturels et les relations phylog6ndtiques de ce genre. Les sdquences de I'ADN nucl6aire codant pour une partie de la grande sous-unit6 ribosomale ont 6t6 ddterminEes et €valu6es en utilisant l'analyse par liaison en lacet avec le voisin (neighbor-joining with bootstrap), l'analyse en parcimonie, le rcgroupement conditionnel et les m€thodes de ressemblance maximale. Les rdsultats confirment substantiellement les sections Afiarira, Caesarea, Uaqinatae, Ualidae, Phalloideae et Amidella, comme groupes monophyldtiques, alors que la monophylie de la section Lepidella demerxe obscure. -

AMATOXIN MUSHROOM POISONING in NORTH AMERICA 2015-2016 by Michael W
VOLUME 57: 4 JULY-AUGUST 2017 www.namyco.org AMATOXIN MUSHROOM POISONING IN NORTH AMERICA 2015-2016 By Michael W. Beug: Chair, NAMA Toxicology Committee Assessing the degree of amatoxin mushroom poisoning in North America is very challenging. Understanding the potential for various treatment practices is even more daunting. Although I have been studying mushroom poisoning for 45 years now, my own views on potential best treatment practices are still evolving. While my training in enzyme kinetics helps me understand the literature about amatoxin poisoning treatments, my lack of medical training limits me. Fortunately, critical comments from six different medical doctors have been incorporated in this article. All six, each concerned about different aspects in early drafts, returned me to the peer reviewed scientific literature for additional reading. There remains no known specific antidote for amatoxin poisoning. There have not been any gold standard double-blind placebo controlled studies. There never can be. When dealing with a potentially deadly poisoning (where in many non-western countries the amatoxin fatality rate exceeds 50%) treating of half of all poisoning patients with a placebo would be unethical. Using amatoxins on large animals to test new treatments (theoretically a great alternative) has ethical constraints on the experimental design that would most likely obscure the answers researchers sought. We must thus make our best judgement based on analysis of past cases. Although that number is now large enough that we can make some good assumptions, differences of interpretation will continue. Nonetheless, we may be on the cusp of reaching some agreement. Towards that end, I have contacted several Poison Centers and NAMA will be working with the Centers for Disease Control (CDC). -

The Ectomycorrhizal Fungus Amanita Phalloides Was Introduced and Is

ADAMS,† HUGH B. CROSS* and THOMAS D. BRUNS‡ *Department of Organismic and Evolutionary Biology, Biological Laboratories, 16 Divinity Avenue, Harvard University, Cambridge, MA 02138, USA, †Department of Biological Sciences, Gilbert Hall, Stanford University, Stanford, CA 94305-5020, USA, ‡Department of Plant and Microbial Biology, 111 Koshland Hall, University of California, Berkeley, CA 94720, USA Abstract The deadly poisonous Amanita phalloides is common along the west coast of North America. Death cap mushrooms are especially abundant in habitats around the San Francisco Bay, California, but the species grows as far south as Los Angeles County and north to Vancouver Island, Canada. At different times, various authors have considered the species as either native or introduced, and the question of whether A. phalloides is an invasive species remains unanswered. We developed four novel loci and used these in combination with the EF1α and IGS loci to explore the phylogeography of the species. The data provide strong evidence for a European origin of North American populations. Genetic diversity is generally greater in European vs. North American populations, suggestive of a genetic bottleneck; polymorphic sites of at least two loci are only polymorphic within Europe although the number of individuals sampled from Europe was half the number sampled from North America. Endemic alleles are not a feature of North American populations, although alleles unique to different parts of Europe were common and were discovered in Scandinavian, mainland French, and Corsican individuals. -

Foraged Mushroom Toxicity Presenting to Urgent Care with Acute Kidney Injury
CME: This article is offered for AMA PRA Category 1 Credit.™ Visit Case Report https://www.urgentcarecme.com/bundles/jucm-cme for further details. Foraged Mushroom Toxicity Presenting to Urgent Care with Acute Kidney Injury Urgent message: Though it occurs relatively rarely, mushroom toxicity can result in irreversible organ damage and, in certain cases, death if not recognized quickly. Diagnosis can be difficult due to the facts that toxicity may present at different intervals from time of ingestion, de- pending on the species of mushroom, and initial symptoms are nonspecific and similar to those of benign gastrointestinal illnesses. Timely consultation with a poison control center may be life-saving. MICHELE L. STOWE, PA-C, MPAS and JOSHUA W. RUSSELL, MD, MSC, FAAEM, FACEP Introduction ushroom foraging is a popular activity in the U.S. MPacific Northwest (PNW). Based on cultural traditions, many Asian and European immigrants commonly forage for mushrooms, as well. A case of mush room misidentification may occur when a poisonous species in the U.S. is mistaken for an edible species in an indi- vidual’s country of origin, which occurs most commonly among species from Europe and Asia. There are also poi- sonous local native species which can be confused with edible species with similar appearances. Amanita smithi- ana is an example of a poisonous native PNW mush- room which is similar in appearance to, and grows in the same densely forested habitat as, an edible species: the pine mushroom (or matsutake as it is known in Asia), which is used in many traditional Asian dishes.1 Amanita smithiana is known to cause delayed renal failure when ingested, due to the nephrotoxic com- pound allenic norleucine.2 Gastrointestinal symptoms generally begin within 6 hours of ingestion, but renal toxicity does not manifest until 1 to 4 days after inges- ©AdobeStock.com tion; as such, it may not be evident on initial laboratory evaluation. -
