High Diversity of Fungi Recovered from the Roots of Mature Tanoak (Lithocarpus Densiflorus) in Northern California
1380 High diversity of fungi recovered from the roots of mature tanoak (Lithocarpus densiflorus)in northern California S.E. Bergemann and M. Garbelotto Abstract: We collected mature tanoak (Lithocarpus densiflorus (Hook. & Arn.) Rehder) roots from five stands to charac- terize the relative abundance and taxonomic richness of root-associated fungi. Fungi were identified using polymerase chain reaction (PCR), cloning, and sequencing of internal transcribed spacer (ITS) and 28S rDNA. A total of 382 cloned PCR inserts were successfully sequenced and then classified into 119 taxa. Of these taxa, 82 were basidiomycetes, 33 were ascomycetes, and 4 were zygomycetes. Thirty-one of the ascomycete sequences were identified as Cenococcum geo- philum Fr. with overall richness of 22 ITS types. Other ascomycetes that form mycorrhizal associations were identified in- cluding Wilcoxina and Tuber as well as endophytes such as Lachnum, Cadophora, Phialophora, and Phialocephela. The most abundant mycorrhizal groups were Russulaceae (Lactarius, Macowanites, Russula) and species in the Thelephorales (Bankera, Boletopsis, Hydnellum, Tomentella). Our study demonstrates that tanoak supports a high diversity of ectomycor- rhizal fungi with comparable species richness to that observed in Quercus root communities. Key words: Cenoccocum geophilum, community, dark septate endophytes, ectomycorrhiza, species richness. Re´sume´ : Les auteurs ont pre´leve´ des racines de Lithocarpus densiflorus (Hook. & Arn.)

New Powdery Mildew on Tomatoes
NEW POWDERY MILDEW ON TOMATOES Heather Scheck, Plant Pathologist Ag Commissioner’s Office, Santa Barbara County POWDERY MILDEW BIOLOGY Powdery mildew fungi are obligate, biotrophic parasites of the phylum Ascomycota of the Kingdom Fungi. The diseases they cause are common, widespread, and easily recognizable Individual species of powdery mildew fungi typically have a narrow host range, but the ones that infect Tomato are exceptionally large. Photo from APS Net POWDERY MILDEW BIOLOGY Unlike most fungal pathogens, powdery mildew fungi tend to grow superficially, or epiphytically, on plant surfaces. During the growing season, hyphae and spores are produced in large colonies that can coalesce Infections can also occur on stems, flowers, or fruit (but not tomato fruit) Our climate allows easy overwintering of inoculum and perfect summer temperatures for epidemics POWDERY MILDEW BIOLOGY Specialized absorption cells, termed haustoria, extend into the plant epidermal cells to obtain nutrition.

A Re-Evaluation of Neotropical Junghuhnia S.Lat. (Polyporales, Basidiomycota) Based on Morphological and Multigene Analyses
Persoonia 41, 2018: 130–141 ISSN (Online) 1878-9080 www.ingentaconnect.com/content/nhn/pimj RESEARCH ARTICLE https://doi.org/10.3767/persoonia.2018.41.07 A re-evaluation of Neotropical Junghuhnia s.lat. (Polyporales, Basidiomycota) based on morphological and multigene analyses M.C. Westphalen1,*, M. Rajchenberg2, M. Tomšovský3, A.M. Gugliotta1 Key words Abstract Junghuhnia is a genus of polypores traditionally characterised by a dimitic hyphal system with clamped generative hyphae and presence of encrusted skeletocystidia. However, recent molecular studies revealed that Mycodiversity Junghuhnia is polyphyletic and most of the species cluster with Steccherinum, a morphologically similar genus phylogeny separated only by a hydnoid hymenophore. In the Neotropics, very little is known about the evolutionary relation- Steccherinaceae ships of Junghuhnia s.lat. taxa and very few species have been included in molecular studies. In order to test the taxonomy proper phylogenetic placement of Neotropical species of this group, morphological and molecular analyses were carried out. Specimens were collected in Brazil and used for DNA sequence analyses of the internal transcribed spacer and the large subunit of the nuclear ribosomal RNA gene, the translation elongation factor 1-α gene, and the second largest subunit of RNA polymerase II gene. Herbarium collections, including type specimens, were studied for morphological comparison and to confirm the identity of collections. The molecular data obtained revealed that the studied species are placed in three different genera. Specimens of Junghuhnia carneola represent two distinct species that group in a lineage within the phlebioid clade, separated from Junghuhnia and Steccherinum, which belong to the residual polyporoid clade. -
Ascocarp Development in Anthracobia Melaloma
AN ABSTRACT OF THE THESIS OF HAROLD JULIUS LARSEN, JR. for the MASTER OF ARTS (Name) (Degree) in BOTANY presented on it (Major) (Date) Title: ASCOCA.RP DEVELOPMENT IN ANTHRACOBIA MELALOMA. Abstract approved:Redacted for privacy William C. Denison Cultural and developmental characteristics of a collection of Anthracobia melaloma with a brown hymeniurn and a barred exterior appearance were examined.It grows well in culture on CM and CMMY agar media and has a growth rate of 17 mm in 18 hours.It is heterothallic and produces asexual rnultinucleate arthrospores after incubation at 300C or above for several days in succession.These arthrospores germinate readily after transfer to fresh media. Antheridial hyphae and archicarps are produced by both mating types although the negative mating type isolates producemore abun- dant archicarps.Antheridia are indistinguishable from vegetative hyphae until just prior to plasmogamy when they become swollen. Septal pads arise on the septa separating the cells of the trichogyne and ascogonium subsequent to plasmogamy and persist throughout development. The paraphyses, the ectal and medullary excipulum, and the excipular hairs are all derived from the sheathing hyphae. Ascogenous hyphae and asci are derived from the largest cells of the ascogonium. A haploid chromosome number of four is confirmed for the species. Exposure to fluorescent light was unnecessary for apothecial induction, but did enhance apothecial maturation and the production of hyrnenial carotenoid pigments.Constant exposure to light inhibited -
Introduction Molds Are a Natural and Important Part of Our Environment
Introduction Molds are a natural and important part of our environment. They are ubiquitous and are found virtually everywhere. Molds produce tiny spores to reproduce. These spores can be found in both indoor and outdoor air and on indoor and outdoor surfaces. When mold spores land on a damp spot, they may begin growing and digesting whatever they are growing on in order to survive, leading to adverse conditions. In response to increasing public concern, a number of government authorities, including the United States EPA, California Department of Health Services and New York City Department of Health, have developed recommendations and guidelines for assessment and remediation of mold. Websites for these organizations can be found at the end of this report. While it is generally accepted that molds can be allergenic and can lead to adverse health conditions in susceptible people, unfortunately there are no widely accepted or regulated interpretive standards or numerical guidelines for the interpretation of microbial data. The absence of standards often makes interpretation of microbial data difficult and controversial. This report has been designed to provide some basic interpretive information using certain assumptions and facts that have been extracted from a number of peer reviewed texts, such as the American Conference of Governmental Industrial Hygienists (ACGIH). In the absence of standards, the user must determine the appropriateness and applicability of this report to any given situation. Identification of the presence of a particular fungus in an indoor environment does not necessarily mean that the building occupants are or are not being exposed to antigenic or toxic agents. -
9B Taxonomy to Genus
Fungus and Lichen Genera in the NEMF Database Taxonomic hierarchy: phyllum > class (-etes) > order (-ales) > family (-ceae) > genus. Total number of genera in the database: 526 Anamorphic fungi (see p. 4), which are disseminated by propagules not formed from cells where meiosis has occurred, are presently not grouped by class, order, etc. Most propagules can be referred to as "conidia," but some are derived from unspecialized vegetative mycelium. A significant number are correlated with fungal states that produce spores derived from cells where meiosis has, or is assumed to have, occurred. These are, where known, members of the ascomycetes or basidiomycetes. However, in many cases, they are still undescribed, unrecognized or poorly known. (Explanation paraphrased from "Dictionary of the Fungi, 9th Edition.") Principal authority for this taxonomy is the Dictionary of the Fungi and its online database, www.indexfungorum.org.

China * Correspondence to: [email protected] Abstract—A new, white-rot, poroid, wood-inhabiting fungal genus, Rhomboidia, typified by R. wuliangshanensis, is proposed based on morphological and molecular evidence. Collected from subtropical Yunnan Province in southwest China, Rhomboidia is characterized by annual, stipitate basidiomes with rhomboid pileus, a monomitic hyphal system with thick-walled generative hyphae bearing clamp connections, and broadly ellipsoid basidiospores with thin, hyaline, smooth walls. Phylogenetic analyses of ITS and LSU nuclear RNA gene regions showed that Rhomboidia is in Steccherinaceae and formed as distinct, monophyletic lineage within a subclade that includes Nigroporus, Trullella, and Flabellophora. Key words—Polyporales, residual polyporoid clade, taxonomy, wood-rotting fungi Introduction Polyporales Gäum. is one of the most intensively studied groups of fungi with many species of interest to fungal ecologists and applied scientists (Justo & al. 2017). Species of wood-inhabiting fungi in Polyporales are important as saprobes and pathogens in forest ecosystems and in their application in biomedical engineering and biodegradation systems (Dai & al. 2009, Levin & al. 2016). With roughly 1800 described species, Polyporales comprise about 1.5% of all known species of Fungi (Kirk & al. -

Karstenia 43: 37-44. 2003. Phellodon secretus Niemela & Kinnunen (Basidiomycota, Thelephorales) resembles Phellodon connatus (Schultz : Fr.) P. Karst., but differs in havi ng a thinner stipe, cottony soft pileus, and smaller and more globose spores. Its ecology is peculiar: it is found in dry, old-growth pine woodlands, growing in sheltered places under strongly decayed trunks or rootstocks of pine trees, where there is a gap of only a few centim eters between soil and wood. Basidiocarps emerge from humus as needle-like, ca. I mm thick, black stipes, and the pileus unfolds only after the stipe tip has contacted the overhanging wood. In its ecology and distribution the species resembles Hydnellum gracilipes (P. Karst.) P. Karst. It seems to be extremely rare, found in Northern boreal and Middle boreal vegetation zones, in areas with fairly continental climate.
