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.

Checklist of Argentine Agaricales 4
Checklist of the Argentine Agaricales 4. Tricholomataceae and Polyporaceae 1 2* N. NIVEIRO & E. ALBERTÓ 1Instituto de Botánica del Nordeste (UNNE-CONICET). Sargento Cabral 2131, CC 209 Corrientes Capital, CP 3400, Argentina 2Instituto de Investigaciones Biotecnológicas (UNSAM-CONICET) Intendente Marino Km 8.200, Chascomús, Buenos Aires, CP 7130, Argentina CORRESPONDENCE TO *: [email protected] ABSTRACT— A species checklist of 86 genera and 709 species belonging to the families Tricholomataceae and Polyporaceae occurring in Argentina, and including all the species previously published up to year 2011 is presented. KEY WORDS—Agaricomycetes, Marasmius, Mycena, Collybia, Clitocybe Introduction The aim of the Checklist of the Argentinean Agaricales is to establish a baseline of knowledge on the diversity of mushrooms species described in the literature from Argentina up to 2011. The families Amanitaceae, Pluteaceae, Hygrophoraceae, Coprinaceae, Strophariaceae, Bolbitaceae and Crepidotaceae were previoulsy compiled (Niveiro & Albertó 2012a-c). In this contribution, the families Tricholomataceae and Polyporaceae are presented. Materials & Methods Nomenclature and classification systems This checklist compiled data from the available literature on Tricholomataceae and Polyporaceae recorded for Argentina up to the year 2011. Nomenclature and classification systems followed Singer (1986) for families. The genera Pleurotus, Panus, Lentinus, and Schyzophyllum are included in the family Polyporaceae. The Tribe Polyporae (including the genera Polyporus, Pseudofavolus, and Mycobonia) is excluded. There were important rearrangements in the families Tricholomataceae and Polyporaceae according to Singer (1986) over time to present. Tricholomataceae was distributed in six families: Tricholomataceae, Marasmiaceae, Physalacriaceae, Lyophyllaceae, Mycenaceae, and Hydnaginaceae. Some genera belonging to this family were transferred to other orders, i.e. Rickenella (Rickenellaceae, Hymenochaetales), and Lentinellus (Auriscalpiaceae, Russulales). -

Mushroom Root Rot Republished for the Internet April 2008
FOREST AND SHADE TREE PESTS Leaflet Number 11 Published Feb 1994 Mushroom Root Rot Republished for the Internet April 2008 SIGNIFICANCE Mushroom Root Rot, caused by the fungus Armillaria tabescens (syn. Clitocybe tabescens and Armillariella tabescens), is a common and widespread disease affecting both conifers and hardwoods in Florida. This disease occurs statewide and has been reported on more than 200 species of trees and shrubs. RECOGNITION Affected plants can show one or more of a variety of symptoms, including: thinning of the crown, yellowing of foliage, premature defoliation, branch dieback, decaying roots, Fig. 1. Typical cluster of mushrooms of Armillaria tabescens. At right, cluster windthrow, and lesions at excavated and displayed to show common base and spore-producing gills under mushroom caps. the root collar. Some host plants show symptoms of decline for several years before dying. Others die rapidly without any obvious prior symptoms. Mushroom root rot can often be identified without laboratory diagnosis. Conspicuous clusters of mushrooms, (Fig. 1.) which sometimes appear near the base of infected trees, are the most easily recognized diagnostic indicators of the disease. These mushrooms are usually produced in the fall, but they can occur at other times as well. When fresh they are tan to brown, fleshy, with gills beneath the cap, and lacking a ring (annulus) around the stem. While the presence of the characteristic mushrooms is a sure indicator of mushroom root rot, the lack of these fruiting bodies does not indicate the absence of disease. Mushrooms are not formed every year and they decay rapidly when they do appear. -

This comprises the largest and highest area of montane habitat in Britain, much of which is in a relatively pristine condition. It contains the main summits and plateaux with their associated corries, rocky cliffs, crags, boulder fields, scree slopes and the higher parts of some glens and passes. The vegeta- tion is influenced by factors such as exposure, snow cover and soil type. The main zone is considered to be one of the most spectacular mountain areas in Britain and is recognised nationally and internationally for the quality of its geology, geomorphology and topographic features, and associated soils and biodiversity. c14.5% of the Cairngorms Partnership area (75,000ha) is land above 600m asl. Upland heathland is the most extensive habitat type in the Cairngorms Partnership area, covering c41% of the area, frequently in mosaics with blanket bog. -

School of Biology, Chemistry, and Forestry, Syracuse, New York 13210 SUMMARY Laetisaria arvalis, a soil-inhabiting basidiomycete, is described from culture as a new species. Descriptions and illustrations of the basidiocarps and cultures are provided and the relationship of L. arvalis to Phanero chaete as well as its potential importance as a biological control agent are discussed. About 1960, M. G. Boosalis isolated a fungus with clamp connections from soil planted to sugar beets (Beta vulgaris L.) for more than 50 yr near Scottsbluff, Scotts Bluff County, Neb. His early studies of this isolate indicated that it might be used as a biological control agent against Thanatephorus cucumerus (Frank) Donk (anamorph : Rhizo ctonia solani Kuhn) the cause of a root rot of sugar beets.

Wood Decay Fungi in Landscape Trees
Pest Notes, Publication 74109 Revised August 2019 Integrated Pest Management for Home Gardeners and Landscape Professionals Wood Decay Fungi in Landscape Trees everal fungal diseases, sometimes called heart rots, Ssap rots, or canker rots, decay wood in tree trunks Figure 1. White rot of oak. and limbs (Figures 1 and 2). Under conditions favor- ing growth of specific rot fungi, extensive portions of the wood of living trees can decay in a relatively short time (i.e., months to years). Decay fungi reduce wood strength and may kill storage and conductive tissues in the sapwood. While most species of woody plants are subject to trunk and limb decay, older and weaker trees are most susceptible. DAMAGE Decay fungi destroy cell wall components; including cellulose, hemicellulose, and lignin, that make up the woody portion of a tree. Depending on the organism, decay fungi can destroy the living (sapwood) or the central core (heartwood) part of the tree. Decay isn’t always visible on the outside of the tree, except where the bark Figure 2. Heart brown rot in a conifer trunk. has been cut or injured, when a cavity is present, or when rot fungi produce reproductive structures. Wood decay can make trees hazardous, of wood weight can result in 70 to 90% as infected trunks and limbs become loss in wood strength. Many branches unable to support their own weight and that fall from trees appear sound, but fall, especially when stressed by wind, upon analysis, they were colonized by Authors: heavy rain, or other conditions.

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. -
A Preliminary Checklist of Arizona Macrofungi
A PRELIMINARY CHECKLIST OF ARIZONA MACROFUNGI Scott T. Bates School of Life Sciences Arizona State University PO Box 874601 Tempe, AZ 85287-4601 ABSTRACT A checklist of 1290 species of nonlichenized ascomycetaceous, basidiomycetaceous, and zygomycetaceous macrofungi is presented for the state of Arizona. The checklist was compiled from records of Arizona fungi in scientific publications or herbarium databases. Additional records were obtained from a physical search of herbarium specimens in the University of Arizona’s Robert L. Gilbertson Mycological Herbarium and of the author’s personal herbarium. This publication represents the first comprehensive checklist of macrofungi for Arizona. In all probability, the checklist is far from complete as new species await discovery and some of the species listed are in need of taxonomic revision. The data presented here serve as a baseline for future studies related to fungal biodiversity in Arizona and can contribute to state or national inventories of biota. INTRODUCTION Arizona is a state noted for the diversity of its biotic communities (Brown 1994). Boreal forests found at high altitudes, the ‘Sky Islands’ prevalent in the southern parts of the state, and ponderosa pine (Pinus ponderosa P.& C. Lawson) forests that are widespread in Arizona, all provide rich habitats that sustain numerous species of macrofungi. Even xeric biomes, such as desertscrub and semidesert- grasslands, support a unique mycota, which include rare species such as Itajahya galericulata A. Møller (Long & Stouffer 1943b, Fig. 2c). Although checklists for some groups of fungi present in the state have been published previously (e.g., Gilbertson & Budington 1970, Gilbertson et al. 1974, Gilbertson & Bigelow 1998, Fogel & States 2002), this checklist represents the first comprehensive listing of all macrofungi in the kingdom Eumycota (Fungi) that are known from Arizona. -
BASIDIOMYCOTINA and ITS CLASSIFICATION Dr
BASIDIOMYCOTINA AND ITS CLASSIFICATION Dr. Vishnupriya Sharma Department of Botany B.Sc sem II, paper 2,Course code 2BOT T2 Title of the Paper- Mycology and Phytopathology Basidiomycotina Diagnostic features of Basidiomycotina 1. Basidiomycotina comprise of about 550 genera 15,000 species 2.Many of them are saprophytes while others are parasitic. These includes mushrooms, toad stools, puff balls, stink horns, shelf fungi, bracket fungi, rusts, and smuts. 3.They have Septate mycelium ,non motile spores and are characterised by the production of a club-shaped structure, known as Basidium 4. Basidium is a cell in which karyogamy and meiosis occurs. However, the basidium produces usually four spores externally known as basidiospores Vegetative structure: The vegetative body is well developed mycelium which consists of septate, branched mass of hyphae which grow on or in the substratum obtaining nourishment from host. Sometimes, a number of hyphae become interwoven to form thick strands of mycelium which are called rhizomorphs. In parasitic species the hyphae are either intercellular, sending haustoria into the cells or intracellular. The colour of the hyphae varies according to the species through three stages before the completion of life cycle. Three stages of development of mycelium The three stages are the primary, the secondary and the tertiary mycelium. The primary mycelium consists of hyphae with uninucleate cells. It develops from the germinating basidiospore. When young, the primary mycelium is multinucleate, but later on, due to the formation of septa, it divides into uninucleate cells. The primary mycelium constitutes the haplophase and never forms basidia and basidiospores. The primary mycelium may produce oidia which are uninucleate spores, formed on oidiophores.
