  • Appendix K. Survey and Manage Species Persistence Evaluation
    Appendix K. Survey and Manage Species Persistence Evaluation Establishment of the 95-foot wide construction corridor and TEWAs would likely remove individuals of H. caeruleus and modify microclimate conditions around individuals that are not removed. The removal of forests and host trees and disturbance to soil could negatively affect H. caeruleus in adjacent areas by removing its habitat, disturbing the roots of host trees, and affecting its mycorrhizal association with the trees, potentially affecting site persistence. Restored portions of the corridor and TEWAs would be dominated by early seral vegetation for approximately 30 years, which would result in long-term changes to habitat conditions. A 30-foot wide portion of the corridor would be maintained in low-growing vegetation for pipeline maintenance and would not provide habitat for the species during the life of the project. Hygrophorus caeruleus is not likely to persist at one of the sites in the project area because of the extent of impacts and the proximity of the recorded observation to the corridor. Hygrophorus caeruleus is likely to persist at the remaining three sites in the project area (MP 168.8 and MP 172.4 (north), and MP 172.5-172.7) because the majority of observations within the sites are more than 90 feet from the corridor, where direct effects are not anticipated and indirect effects are unlikely. The site at MP 168.8 is in a forested area on an east-facing slope, and a paved road occurs through the southeast part of the site. Four out of five observations are more than 90 feet southwest of the corridor and are not likely to be directly or indirectly affected by the PCGP Project based on the distance from the corridor, extent of forests surrounding the observations, and proximity to an existing open corridor (the road), indicating the species is likely resilient to edge- related effects at the site.

  • 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).

Abstract: The polypore Bridgeoporus nobilissimus produces large perennial basidiocarps on large diameter Abies stumps, snags and trees in coniferous forests of the Pacific Northwest. Despite the size and persistence of the basidiocarps, they are rarely observed, making the conservation of this species a concern. We determined that a genetic marker for this fungus could be detected in DNA extracted from wood cores taken from trees hosting basidiocarps. We then tested 105 trees and stumps that did not host B. nobilissimus basidiocarps in plots surrounding B. nobilissimus conks, and 291 trees and stumps in randomly located plots in four stands that contained at least one B. nobilissimus basidiocarp. We found that trees of all sizes throughout all of the stands hosted B.

Lam. – a new rising opportunity for biomedicine. Pharmacia 67(4): 317–323. https://doi.org/10.3897/pharmacia.67. e56112 Abstract Amanita muscaria, commonly known as fly agaric, is a basidiomycete. Its main psychoactive constituents are ibotenic acid and mus- cimol, both involved in ‘pantherina-muscaria’ poisoning syndrome. The rising pharmacological and toxicological interest based on lots of contradictive opinions concerning the use of Amanita muscaria extracts’ neuroprotective role against some neurodegenerative diseases such as Parkinson’s and Alzheimer’s, its potent role in the treatment of cerebral ischaemia and other socially significant health conditions gave the basis for this review. Facts about Amanita muscaria’s morphology, chemical content, toxicological and pharmacological characteristics and usage from ancient times to present-day’s opportunities in modern medicine are presented.

Its common name suggests MR Lee Abstract that it had been used to kill flies, until superseded by arsenic. The bioactive 112 Polwarth Terrace compounds occurring in the mushroom remained a mystery for long Merchiston periods of time, but eventually four hallucinogens were isolated from the Edinburgh EH11 1NN fungus: muscarine, muscimol, muscazone and ibotenic acid. UK The shamans of Eastern Siberia used the mushroom as an inebriant and a hallucinogen. In 1912, Henry Dale suggested that muscarine (or a closely related substance) was the transmitter at the parasympathetic nerve endings, where it would produce lacrimation, salivation, sweating, bronchoconstriction and increased intestinal motility. He and Otto Loewi eventually isolated the transmitter and showed that it was not muscarine but acetylcholine. The receptor is now known variously as cholinergic or muscarinic. From this basic knowledge, drugs such as pilocarpine (cholinergic) and ipratropium (anticholinergic) have been shown to be of value in glaucoma and diseases of the lungs, respectively.

  • Revised Taxonomy and Phylogeny of an Avian-Dispersed Neotropical Rhizomorph-Forming Fungus
    Mycological Progress https://doi.org/10.1007/s11557-018-1411-8 ORIGINAL ARTICLE Tying up loose threads: revised taxonomy and phylogeny of an avian-dispersed Neotropical rhizomorph-forming fungus Rachel A. Koch1 & D. Jean Lodge2,3 & Susanne Sourell4 & Karen Nakasone5 & Austin G. McCoy1,6 & M. Catherine Aime1 Received: 4 March 2018 /Revised: 21 May 2018 /Accepted: 24 May 2018 # This is a U.S. Government work and not under copyright protection in the US; foreign copyright protection may apply 2018 Abstract Rhizomorpha corynecarpos Kunze was originally described from wet forests in Suriname. This unusual fungus forms white, sterile rhizomorphs bearing abundant club-shaped branches. Its evolutionary origins are unknown because reproductive struc- tures have never been found. Recent collections and observations of R. corynecarpos were made from Belize, Brazil, Ecuador, Guyana, and Peru. Phylogenetic analyses of three nuclear rDNA regions (internal transcribed spacer, large ribosomal subunit, and small ribosomal subunit) were conducted to resolve the phylogenetic relationship of R. corynecarpos. Results show that this fungus is sister to Brunneocorticium bisporum—a widely distributed, tropical crust fungus. These two taxa along with Neocampanella blastanos form a clade within the primarily mushroom-forming Marasmiaceae. Based on phylogenetic evidence and micromorphological similarities, we propose the new combination, Brunneocorticium corynecarpon, to accommodate this species. Brunneocorticium corynecarpon is a pathogen, infecting the crowns of trees and shrubs in the Neotropics; the long, dangling rhizomorphs with lateral prongs probably colonize neighboring trees. Longer-distance dispersal can be accomplished by birds as it is used as construction material in nests of various avian species. Keywords Agaricales . Fungal systematics .

  • Paddy Straw Mushroom (433)
    Pacific Pests, Pathogens and Weeds - Online edition Paddy straw mushroom (433) Common Name Paddy straw mushroom, straw mushroom, Chinese mushroom. Scientific Name Volvariella volvacea Distribution It is cultivated widely in East and Southeast Asia, and introduced in many other regions, including Africa, North America and Australia. It is recorded from Solomon Islands. Use & Appearance The paddy straw mushroom is grown on rice straw beds and picked immature, during the button or egg phase and before the veil ruptures (Photo 1). It is found in woodchips, rich garden Photo 1. Button stage of the paddy straw soil, compost piles and, in the Pacific, on decaying trunks of fallen sago palm and empty fruit mushroom, Volvariella volvacea, showing bunches of oil palm. They are often available fresh in Asia, but are more frequently found canned many still enclosed in the veil, and others or dried in countries where they are not cultivated. where the veil has broken. Methods of cultivation are here: http://www.fao.org/3/ca4450en/ca4450en.pdf. Young stages are formed under a greyish-brown veil (‘universal veil’), which surrounds the mushroom at the ‘button stage’ (Photo 2). It breaks to allow the stem and cap to expand leaving a dark brown cup-shaped structure (the ‘volva’) at the base (Photo 2). The cap is 5-12 cm diameter, first ovoid, then cone-like and finally broadly convex or bell- shaped, dark grey in the centre, becoming silvery-white or brownish-grey towards the margins, radially streaked with soft hairs (Photo 3). The cap tends to split at the edges.

  • Poisonous Mushrooms
    POISONOUS MUSHROOMS DR. SURANJANA SARKAR ASSISTANT PROFESSOR IN BOTANY, SURENDRANATH COLLEGE, KOLKATA Dr. Suranjana Sarkar, SNC INTRODUCTION It was difficult not to since eating wild mushrooms and mushroom poisoning seem to be closely related subjects. This is a rather important topic since mushrooms have apparently been gathered for eating throughout the world, for thousands of years, and it is also likely that during that time many people became ill or died when they inadvertently consumed poisonous mushrooms. Because some mushrooms were known to cause death when consumed, they were also known to be used by assassins. Dr. Suranjana Sarkar, SNC Used as Poison in Assassinations and Murders The most famous of all planned murders was that of Emperor Claudius by his fourth wife, Agrippina, The Younger (also his niece!). The story behind this assassination, as well as the political intrigue that was present during this period of the Roman Empire would have made a great mini series or soap opera. Claudius became emperor, in 41 A.D., following the assassination of his nephew Caligula, and married Agrippina, his fourth wife, after disposing of Messalina, his third wife, for adultery. Agrippina came into the marriage with Nero, a son from a previous marriage and wanted him to follow Claudius as emperor. Agrippina persuaded him to adopt her son so that Nero would be in line to become emperor. Once Nero was adopted, Agrippina plotted to kill Claudius, which involved a number of people. Although ClaudiusDr. Suranjana Sarkar,had SNCa son, Brittanicus, by Messalina, and should have succeeded him as emperor, Claudius shielded him from the responsibilities as heir to the throne and promoted Nero as his successor.
