Relationship Between the Conformation of the Cyclopeptides Isolated from the Fungus Amanita Phalloides (Vaill. Ex Fr.) Secr. and Its Toxicity
Molecules 2000, 5 489 Relationship Between the Conformation of the Cyclopeptides Isolated from the Fungus Amanita Phalloides (Vaill. Ex Fr.) Secr. and Its Toxicity M.E. Battista, A.A. Vitale and A.B. Pomilio PROPLAME-CONICET, Departamento de Química Orgánica, Facultad de Ciencias Exactas y Natu- rales, Universidad de Buenos Aires, Pabellón 2, Ciudad Universitaria, 1428 Buenos Aires, Argentina E-mail: [email protected] Abstract: The electronic structures and conformational studies of the cyclopeptides, O- methyl-α-amanitin, phalloidin and antamanide, were obtained from molecular parameters on the basis of semiempiric and ab initio methods. Introduction During this century Amanita phalloides - the most toxic fungus known up to now - has been studied from different points of view. This basidiomycete biosynthesizes mono- and bicyclic peptides com- posed of rare amino acids. In order to determine the structure/activity relationships chemical modifica- tions were carried out and the properties of these compounds were evaluated. These results were con- firmed by studying the conformations of three selected compounds representative of the major groups of the macroconstituents of this fungus. Experimental Hyperchem package (HyperCube, version 5.2) was used for semiempirical studies, the molecular geometry being optimized by STO-631G. Net charges were calculated with HyperCube PM3 and the Polack-Ribiere algoritm. GAUSSIAN 98 was used for ab initio studies. Results and Discussion We were interested in obtaining information on the conformations that the cyclic peptides may adopt and about the potential energy maps in order to locate the regions related to the binding to pro- tein molecules, such as F-actin and RNA-polymerase. -
Diversity and Phylogeny of Suillus (Suillaceae; Boletales; Basidiomycota) from Coniferous Forests of Pakistan
INTERNATIONAL JOURNAL OF AGRICULTURE & BIOLOGY ISSN Print: 1560–8530; ISSN Online: 1814–9596 13–870/2014/16–3–489–497 http://www.fspublishers.org Full Length Article Diversity and Phylogeny of Suillus (Suillaceae; Boletales; Basidiomycota) from Coniferous Forests of Pakistan Samina Sarwar * and Abdul Nasir Khalid Department of Botany, University of the Punjab, Quaid-e-Azam Campus, Lahore, 54950, Pakistan *For correspondence: [email protected] Abstract Suillus (Boletales; Basidiomycota) is an ectomycorrhizal genus, generally associated with Pinaceae. Coniferous forests of Pakistan are rich in mycodiversity and Suillus species are found as early appearing fungi in the vicinity of conifers. This study reports the diversity of Suillus collected during a period of three (3) years (2008-2011). From 32 basidiomata of Suillus collected, 12 species of this genus were identified. These basidiomata were characterized morphologically, and phylogenetically by amplifying and sequencing the ITS region of rDNA. © 2014 Friends Science Publishers Keywords: Moist temperate forests; PCR; rDNA; Ectomycorrhizae Introduction adequate temperature make the environment suitable for the growth of mushrooms in these forests. Suillus (Suillaceae, Basidiomycota, Boletales ) forms This paper described the diversity of Suillus (Boletes, ectomycorrhizal associations mostly with members of the Fungi) with the help of the anatomical, morphological and Pinaceae and is characterized by having slimy caps, genetic analyses as little knowledge is available from forests glandular dots on the stipe, large pore openings that are in Pakistan. often arranged radially and a partial veil that leaves a ring or tissue hanging from the cap margin (Kuo, 2004). This genus Materials and Methods is mostly distributed in northern temperate locations, although some species have been reported in the southern Sporocarp Collection hemisphere as well (Kirk et al ., 2008). -

Mushroom Basics by Dan Gill, Ethno-Gastronomist
Mushroom Basics By Dan Gill, Ethno-Gastronomist Photos compliments of “Wildman” Steve Brill http://www.wildmanstevebrill.com The Good White Morel Morchella deliciosa I was working in the woods on a fine spring day several years ago, when I thought I smelled mushrooms. Looking around the mixed hardwood stand dominated by Tulip Poplars, I noticed a lot of Sweetgum balls. When I looked closer, I realized that many were actually morel mushrooms in camouflage. Once my eyes and brain adapted to the difference, I realized that I was surrounded by a stealthy delicacy, some six inches high. I ran for some brown paper bags and picked several pounds. Though I have found edible mushrooms in every month of the year, the season really begins, at least psychologically, in early spring with the emergence of morels, or “merkles” as they are known by many mushroomers. Start looking around apple blossom time when wild asparagus and May Apples are up and oak leaves are the size of squirrel’s ears, or about mid April. Morels are sometimes found in unusual places, such as mulch piles and lawns (especially near elm trees), but they often inhabit old apple orchards, Tulip Poplar stands and burned over woodlands. If you find more than you can use right away, call me – I will even help you pick them! Otherwise dry them. Morel flavor actually intensifies with drying. There are many excellent edibles, besides morels, that grow in abundance throughout Virginia and are easily identified, once you know what to look for. The differences and points of distinction are characteristic and quite obvious: Is the cap of a certain color, texture or feel? Does it have gills, pores or spikes underneath? What color are the gills and spore print? Does it grow on the ground or on trees, in the woods or on lawns? Once you have seen, touched, smelled and tasted a specific mushroom, it is like telling the difference between an apple and a tomato. -

The members, as well as the mushrooms, rose to the occasion, despite brutal conditions for collecting which included a sideways driving rain (which we photo by Pam Anderson thought had come too late), and even a thunderstorm, as we prepared to gather for the greatly anticipated sorting of our catch at the hallowed Bloedel Donovan Community Building.

Species of Hygrocybe Subgenus Cuphophyllus Hygrophorus Flavipes
PERS OONIA Published by the Rijksherbarium, Leiden 43-46 Volume 14, Part 1, pp. (1989) Notes on Hygrophoraceae — XI. Observations on some species of Hygrocybe subgenus Cuphophyllus Eef Arnolds Biological Station, Wijster (Drente), Netherlands* The nomenclature of the violaceous of grey species Hygrocybe subgenus Cuphophyllus and the taxonomic position of H. subradiata are discussed. One new species is described and onenew combination is made, viz. Hygrocybe radiata and H. flavipes. In Europe usually two species with a grey violaceous to lilac pileus are distinguished within Hygrocybe subgenus Cuphophyllus Donk (= Camarophyllus sensu auct.), named H. subvio- lacea (Peck) Orton & Watl. and H. lacmus (Schum.) Orton & Watl. The former species is characterized by an entirely white stipe and aromatic smell, whereas the latter species has a yellow base of stipe and no characteristic smell. Recently, Raid& Boertmann (1988) demonstrated that the name Agaricus lacmus Schum. has been since Schumacher did mention (1803: 333) currently misinterpreted not a yellow base of stipe in the original description and an unpublished, authentic plate by that author shows white lacmus Schum. is an entirely stipe. Consequently, Agaricus an earlier synonym ofHygrophorus subviolaceus Peck (1900: 82) and H. lacmus sensu auct. (with a yellow stipe base) should have a new name. According to Raid & Boertmann (1988) the oldest available name is Hygrophorus flavipes Britz. This epithet was not yet combinedin Hygrocybe and thereforethe following combina- tion is proposed: Hygrocybe flavipes (Britz.) Arnolds, comb. nov. — Basionym: Hygrophorus flavipes Britz., Hymenomyc. Stidbayern 8: 10, fig. 69. 1891. Some authors (Clemengon, 1982; Bon, 1984) distinguished two species with a yellow base of stipe, differing in spore size only: Camarophyllus lacmus sensu C16mengon with ellip- soid to lacrimiform of 6.5-8 x 4.5-6 and C. -
