SPOROCAONTOGENYRP IN PANUS(BASIDIOMYCOTINA): EVOLUTION AND CLASSIFICATION ' DAVIDS . HIBBETTSHIGEYUKI,~ MURAKAMI, AN D AKIHIKOTSUNEDA Tottori Mycological Institute, 21 1 Kokoge, Tottori 689-1 1 Japan Ontogenies of cultured Panus conchatus, P. rudis, and P. fulvus sporocarps were observed macroscopically and with scanning electron microscopy. Hymenophore differentiation in Panus involves periclinal growth of context hyphae below a closed surface palisade of hymenial elements, resulting in a cantharelloid appearance and radiate trama. This pattern is qualitatively different from that in Lentinus s. str., which suggests that lamellae of Panus and Lentinus are not homologous. Panus conchatus and P. rudis sporocarps have short stipes, develop directly from the mycelium, and mature in 5-10 d. Panus fulvus sporocarps have an elongate stipe, develop from a pseudosclerotium, and mature in about 3 wk, the first approximately 15 d of which involve apical elongation of a stipelike primordium that is able to dedifferentiate and regenerate cut apices. Panus conchatus and P. rudis sporocarps lacked regeneration ability. Panus conchatus sporocarps developed an ephemeral partial veil that was obliterated during sporocarp expansion. Outgroup comparison suggests that evolutionary changes in developmental programs in Panus have included: 1) delay in offset of primordium growth, with a corresponding increase in primordium size and time to maturation (hypermorphosis); 2) insertion of the pseudosclerotial stage in ontogeny; 3) gain of ability for dedifferentiation and regeneration; and 4) nonterminal gain or loss of veil tissue.

    Belowground Microbial Processes Underpin Forest Productivity By C. Y. LI1) & E. STRZELCZYK2) Key words : Microbial processes, ecological functions, microbial interactions. Summary LI C. Y. & STRZELCZYK E. 2000. Belowground microbial processes underpin forest pro- ductivity. - Phyton (Horn, Austria) 40 (4): (129) - (134). Nitrogen-fixing bacteria associated with mycorrhizal fungi and mycorrhizas can be dem- onstrated with microaerophilic procedures. The chemical substrates in mycorrhizal fungi or mycorrhizas often stimulate the growth and nitrogenase activity of the associated N2 fixers. In addition, the associ- ated N2 fixers are producers of plant-growth-promoting substances and B-group vitamins. Combined inoculation of mycorrhizal fungi with N2 fixers enhances mycorrhiza formation. Other microbes in the mycorrhizosphere have capacities to breakdown primary minerals, thereby releasing nutrients available for uptake by plants. Thus, land restoration can be achieved by planting trees with nitrogen-fixing and rock weathering capacities, such as alders and some pines. The treatment can enhance nutrient availability and increase soil organic matter that provides organic substrate for nutri- ent release, maintain soil structure and enhance water-holding capacity. Also changes in tree species compositions on the site are likely to alter belowground processes through changes in functional processes of organisms that constitute ecosystems. Introduction Soil microbial populations are metabolically active in the mycorrhizosphere, where a continuous

    PLP427R/527R 11-1-05 NAME: QUIZ # 3 1. Described the common features of the organisms placed in the Deuteromycota, and how the classes and orders within this phylum are based on form? Explain why this phylum is decreasing in size even though more fungal species are being identified. The organisms in the phylum Deuteromycota are those higher fungi that only have an anamorphic (asexual) stage. They lack a known sexual (teleomorphic) stage. The Deuteromycota is often referred to as a Form-phylum because the organisms are grouped based on form, and may not be the most closely related. As such, groupings are polyphyletic. The classes are defined based on first whether they produce hyphae (Coelomycetes and Hyphomycetes) or are yeast-like (Blastomycetes), and if they do produce hyphae, whether the conidiophores and conidia occur in structures (pycnidia and acervuli) (the Coelomycetes) or not the Hyphomycetes). Orders are based on the type of structure for one class (the Coelomycetes), and on whether or not they produce conidia, or only hyphae for the class lacking asexual spore-bearing structures (the Hyphomycetes). The phylum is decreasing in size primarily because organisms are being re- classified into the Ascomycetes, or some into the Basidiomycetes, based on their molecular phylogenetic relatedness to other species already in those phyla. Some already do not recognize this group as a separate phylum (eg. Kendrick, author of the Fifth Kingdom).. 2.

Current Research in Environmental & Applied Mycology 8(5), 501–555, Doi 10.5943/cream/8/5/3 Abstract Conventional taxonomy of mushrooms is often not very easy for amateur taxonomists and research scholars to initiate the research on taxonomy and diversity of mushrooms due to the complex morphological characteristics that is often very difficult to comprehend. We illustrate the external morphological characteristics of mushrooms through colorful photographs to facilitate the taxonomic characterization of mushrooms and to promote the research on mushrooms. In addition, a data sheet for morphological characteristics of agaric mushrooms is provided. Key words – agarics – basidiomycetes – fungi – morphology – mushrooms – polypores – taxonomy Introduction It is an endeavor to simplify the morphological characteristics of mushrooms and to make known to the amateur mycologists beyond a shadow of doubt for easy identification of mushrooms. Although, several materials and field guides in the form of drawings are available for illustrating the morphotaxonomy of mushrooms (Largent & Stuntz 1977, Singer 1986, Lodge et al. 2004), still amateur mushroom taxonomists feel it tiresome to take up initial research on mushrooms due to an array of mushroom characteristics to be recorded.

Singer (1947) compared Pleurocollybia to two morphologically similar genera, Callistosporium Singer and Podabrella Singer (now considered a synonym of Termitomyces, Frøslev et al. 2003), but separated Pleurocollybia from them by the eccentric stipe and very small basidiospores.

Podabrella (= Termitomyces) also produces siderophilous bodies in the basidia, while siderophilous bodies are not present in Pleurocollybia. Callistosporium has abundant brightly colored necropigments in the basidiospores, basidia and tramal hyphae, while these pigments are not present in Pleurocollybia.

The finest naturalists have always known that biology without romance, without poetry, is not only incomplete but very often hopelessly distorted" — Frank Graham Jr., 1983 AN ABSTRACT OF THE THESIS OF Daniel L. Luoma for the degree of Doctor of Philosophy in Geography presented on December 16. 1988. Title: Biomass and Community Structure of Sporocarps Formed by Hypogeous Ectomycorrhizal Fungi within Selected Forest Habitats of the H. J. Andrews Experimental Forest. Oregon Abstract approved: Robert E. Frenkel This study characterizes the production of hypogeous sporocarps (broadly referred to as truffles) by ectomycorrhizal fungi within Douglas-fir dominated forests that are considered typical of those found on the west slopes of the central Cascade mountains in Oregon. Three aspects of sporocarp production are addressed: 1) the distribution of total biomass and biomass of each species by season and habitat, 2) analysis of sporocarp biomass from the perspective of community structure, and 3) correlation of biomass production with sporocarp number and selected forest floor parameters. Sporocarps with an equivalent dry standing biomass of 1.3 kg/ha were harvested from ten Douglas-fir stands in and near the H. J. Andrews Experimental forest. The maximum single stand sample biomass was equivalent to 9.9 kg/ha.

    Bot 316 Mycology and Fungal Physiology

    BOT 316 MYCOLOGY AND FUNGAL PHYSIOLOGY Dr Osondu Akoma 2011 BOT 316 MYCOLOGY AND FUNGAL PHYSIOLOGY INTRODUCTION HISTORICAL BACKGROUND Mycology is a classical translation of the Greek word Mykes logos which means mushroom discussion, thus mycology is the study of fungi. In the past this area of science was limited to the study of mushrooms but as science developed, the scope of the subject widened far beyond the objects seen with the naked eyes with the discovery of microscopes. The development of mycology cannot be isolated from that of science. The ancestry of fungi is ancient, dating back to the Devonian and Precambrian eras. The history is also influenced by calamities and man has always kept record from time and as such the first record of fungi was not that of observing fungi directly but that of their harmful effects. The Romans and Greeks have a lot in their records. Even in the Holy Bible there are many references of the fungi and their effects; Leviticus 14: 4-48, 1Kings 8:37, Deuteronomy 28:22. The first indication that man saw fungi as food was a report of death at Icarius. The first book devoted to fungi is the Van Sterbeek’s “Theatrum Fungerium” in 1675 and this work distinguished the edible from the poisonous mushrooms. The discovery of the microscope led to the systematic study of the fungi. Robert Hooke was credited with the first illustration of micro fungi in 1667 in his work titled Micrographa . The Greeks and Romans regarded fungi as mysterious things. They were regarded as the “evil formats of the earth originating from the mouth of vipers”.

In an effort to under- Received 12 August 2015 stand the genetic basis of endophytism, we compared the genome contents of X. heveae Received in revised form and 36 other Ascomycota with diverse lifestyles and nutritional modes. We focused on 18 September 2015 genes that are known to be important in the hostefungus interaction interface and that Accepted 5 October 2015 presumably have a role in determining the lifestyle of a fungus. We used phylogenomic Available online 22 October 2015 data to infer the higher-level phylogenetic position of the Xylonomycetes, and mined ITS Corresponding Editor: sequences to explore its taxonomic and ecological diversity.
