    The Mycological Society of San Francisco • March 2013, vol. 64:07 March 19 MycoDigest: General Meeting Speaker Clitocybe Sclerotoidea A Most Wonderful Parasite of Helvella Vespertina Nhu Nguyen love parasites. They are just some of the neatest things; except when I’m forced to play host. Parasites come in all sorts of shapes and sizes and it is thought that Ievery species on earth has a parasite of some sort. Animals have parasites, plants have parasites, and fungi too have parasites. I can talk about parasites all day (yes, that parasitology class in college right before lunch three times a week left quite the impression), but I will focus on just one this time. Mycoparasites are fungi that parasitize other fungi and they commonly occur in the mushroom world. Typically the more colorful or pronounced ones get more noticed. Examples of col- orful parasites would be Hypomyces chrysosporium, a common parasite on boletes on the west coast with golden Nhu Nguyen spores.

  • Amanita Muscaria (Fly Agaric)
    J R Coll Physicians Edinb 2018; 48: 85–91 | doi: 10.4997/JRCPE.2018.119 PAPER Amanita muscaria (fly agaric): from a shamanistic hallucinogen to the search for acetylcholine HistoryMR Lee1, E Dukan2, I Milne3 & Humanities The mushroom Amanita muscaria (fly agaric) is widely distributed Correspondence to: throughout continental Europe and the UK. Its common name suggests MR Lee Abstract that it had been used to kill flies, until superseded by arsenic.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. Keywords acetylcholine, atropine, choline, Dale, hyoscine, ipratropium, Loewi, muscarine, pilocarpine, physostigmine Declaration of interests No conflicts of interest declared Introduction recorded by the Swedish-American ethnologist Waldemar Jochelson, who lived with the tribes in the early part of the Amanita muscaria is probably the most easily recognised 20th century.

Accepted 11 November, 2011 A new genus of Agaricales, Leucocalocybe was erected for a species Tricholoma mongolicum in this study. Leucocalocybe was distinguished from the other genera by a unique combination of macro- and micro-morphological characters, including a tricholomatoid habit, thick and short stem, minutely spiny spores and white spore print. The assignment of the new genus was supported by phylogenetic analyses based on the LSU sequences. The results of molecular analyses demonstrated that the species was clustered in tricholomatoid clade, which formed a distinct lineage. Key words: Agaricales, taxonomy, Tricholoma, tricholomatoid clade. INTRODUCTION The genus Tricholoma (Fr.) Staude is typified by having were re-described. Based on morphological and mole- distinctly emarginate-sinuate lamellae, white or very pale cular analyses, T. mongolicum appears to be aberrant cream spore print, producing smooth thin-walled within Tricholoma and un-subsumable into any of the basidiospores, lacking clamp connections, cheilocystidia extant genera. Accordingly, we proposed to erect a new and pleurocystidia (Singer, 1986). Most species of this genus, Leucocalocybe, to circumscribe the unique genus form obligate ectomycorrhizal associations with combination of features characterizing this fungus and a forest trees, only a few species in the subgenus necessary new combination.

  • 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.

Bot. Fennici 40: 213–218. Agaricus nebularis Batsch : Fr. is approved as the lectotype of the genus Clitocybe (Fr.) Staude (Agaricales: Tricholomataceae). Lepista (Fr.) W.G. Smith is a younger taxonomic synonym. Diagnostic characters of Clitocybe are discussed; among the less known ones are: (i) a proportion of the detached spores adhere in tetrads in microscopic mounts, (ii) the spore wall is cyanophilic, and (iii) the mycelium is capable of reducing nitrate. Three new nomenclatural combinations in Clitocybe are made. The new genus Infundibulicybe Harmaja, with Agaricus gibbus Pers. : Fr. as the type, is segregated for the core group of those species of Clitocybe s. lato that do not fi t to the genus as defi ned here. Infundibulicybe mainly differs from Clitocybe in that: (i) the spores do not adhere in tetrads, (ii) all or a proportion of the spores have confl uent bases, (iii) all or most of the spores are lacrymoid in shape, (iv) the spore wall is cyanophobic, and (v) the mycelium is incapable of reducing nitrate. Thirteen new nomenclatural combinations in Infundibulicybe are made. Two new nomenclatural combinations are made in Ampulloclitocybe Redhead, Lutzoni, Moncalvo & Vilgalys (syn.
