1 Anthropogenic N Deposition Increases Soil C Storage By Anthropogenic N deposition increases soil C storage by reducing the relative abundance of lignolytic fungi. Elizabeth M. Entwistle, Donald R. Zak, and William A. Argiroff. Ecological Monographs. APPENDIX S4 Table S1. Top ten SIMPER results for each type of sample for each collection date. These ten operational taxonomic units (OTUs) had the highest dissimilarity scores between fungal communities under ambient and experimental N deposition, respectively. The low-lignin (LL), high-lignin (HL), and wood (W) substrates were collected after 7 and 18 months of decomposition, while forest floor (FF) and soil (S) were co-collected during the 7-month sampling date. For each OTU, we list its average dissimiliarity score, its dissimilarity over its standard deviation (SD), and its contribution (%) to total dissimilarity; we additionally list its average proportional abundance under ambient and experimental N deposition, as well the difference between treatments with declines in mean abundance under experimental N deposition denoted in bold. Furthermore, we list the top BLAST® match to an identified species with outdated nomenclatures retained in parentheses. Based on our knowledge of the biology of these taxa, we gave each OTU a functional assignment: white-rot and lignolytic litter decay (WRL), soft-rot and celluloytic/hemicelluloytic litter decay (SRCH), brown-rot (BR), weakly lignolytic (WL) and mycorrhizal/biotrophic (MB), with a question mark added (?) if the assignment was tentative. Taxa were assigned to the phyla Basidiomycota (B) and Ascomycota (A), subphyla Agaricomycotina (Ag) and Pezizomycotina (Pez), with assignments to to class, order, and family abbreviated by leaving off the -mycetes, -ales, and -aceae, respectively. months of decomposition of months decomposition functional assignment assignment functional Average dissimilarity dissimilarity Average contribution (%) contribution Dissimilarity/SD Dissimilarity/SD Sample type type Sample average OTU proportional Top BLAST match for an taxonomic placement for that species abundance of each identified species OTU 1 sequence identity (%) identity sequence query coverage (%) (%) query coverage experimental N GenBank ID # GenBank ID Subdivision Subdivision ambient N N ambient phylum phylum change change family genus genus order order class class name WRL WRL Mycena AY20725 F - 4 1.5 1.5 4.8 0.101 0.030 0.071 sanguinolent 99 100 B Ag Agarico Agaric Mycen Mycena 7 a WRL (?)

  • Appendix K. Survey and Manage Species Persistence Evaluation
    Appendix K. Survey and Manage Species Persistence Evaluation Establishment of the 95-foot wide construction corridor and TEWAs would likely remove individuals of H. caeruleus and modify microclimate conditions around individuals that are not removed. The removal of forests and host trees and disturbance to soil could negatively affect H. caeruleus in adjacent areas by removing its habitat, disturbing the roots of host trees, and affecting its mycorrhizal association with the trees, potentially affecting site persistence. Restored portions of the corridor and TEWAs would be dominated by early seral vegetation for approximately 30 years, which would result in long-term changes to habitat conditions. A 30-foot wide portion of the corridor would be maintained in low-growing vegetation for pipeline maintenance and would not provide habitat for the species during the life of the project. Hygrophorus caeruleus is not likely to persist at one of the sites in the project area because of the extent of impacts and the proximity of the recorded observation to the corridor. Hygrophorus caeruleus is likely to persist at the remaining three sites in the project area (MP 168.8 and MP 172.4 (north), and MP 172.5-172.7) because the majority of observations within the sites are more than 90 feet from the corridor, where direct effects are not anticipated and indirect effects are unlikely. The site at MP 168.8 is in a forested area on an east-facing slope, and a paved road occurs through the southeast part of the site. Four out of five observations are more than 90 feet southwest of the corridor and are not likely to be directly or indirectly affected by the PCGP Project based on the distance from the corridor, extent of forests surrounding the observations, and proximity to an existing open corridor (the road), indicating the species is likely resilient to edge- related effects at the site.

  • 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.

Bettini 14/11, I16162 Genova, Italy Abstract— The paper is aimed at integrating and updating the first edition of the checklist of Ligurian macrofungi. Data are related to mycological researches carried out mainly in some holm-oak woods through last three years. The new taxa collected amount to 172: 15 of them belonging to Ascomycota and 157 to Basidiomycota. It should be highlighted that 12 taxa have been recorded for the first time in Italy and many species are considered rare or infrequent. Each taxa reported consists of the following items: Latin name, author, habitat, height, and the WGS-84 Global Position System (GPS) coordinates. This work, together with the original Ligurian checklist, represents a contribution to the national checklist. Key words—mycological flora, new reports Introduction Liguria represents a very interesting region from a mycological point of view: macrofungi, directly and not directly correlated to vegetation, are frequent, abundant and quite well distributed among the species. This topic is faced and discussed in Zotti & Orsino (2001). Observations prove an high level of fungal biodiversity (sometimes called “mycodiversity”) since Liguria, though covering only about 2% of the Italian territory, shows more than 36 % of all the species recorded in Italy.

  • Records of Rare Aphyllophoroid Fungi on Scots Pine in Northern Sweden
    Karstenia 50: 45–52, 2010 Records of rare aphyllophoroid fungi on Scots pine in northern Sweden TORBJÖRN JOSEFSSON and VIACHESLAV A. SPIRIN JOSEFSSON, T. & SPIRIN, V.A. 2010: Records of rare aphyllophoroid fungi on Scots pine in northern Sweden – Karstenia 50: 45–52. Helsinki ISSN: 0453-3402. Wood-inhabiting fungi on Pinus sylvestris were examined in three old-growth forests in northern Sweden. A total of 16 rare species of aphyllophoroid fungi are reported. Among the species discussed are Antrodiella pallasii and Skeletocutis kuehneri which are successors of Trichaptum species and previously known from only a few localities in Sweden, and Byssoporia terrestris and Hydnellum gracilipes which are mycorrhizal species with specific ecological preferences. Three corticioid species from generaCera - ceomyces and Sistotrema represent possible new taxa.

  • Polypore Fungi As a Flagship Group to Indicate Changes in Biodiversity – a Test Case from Estonia Kadri Runnel1* , Otto Miettinen2 and Asko Lõhmus1
    Runnel et al. IMA Fungus (2021) 12:2 https://doi.org/10.1186/s43008-020-00050-y IMA Fungus RESEARCH Open Access Polypore fungi as a flagship group to indicate changes in biodiversity – a test case from Estonia Kadri Runnel1* , Otto Miettinen2 and Asko Lõhmus1 Abstract Polyporous fungi, a morphologically delineated group of Agaricomycetes (Basidiomycota), are considered well studied in Europe and used as model group in ecological studies and for conservation. Such broad interest, including widespread sampling and DNA based taxonomic revisions, is rapidly transforming our basic understanding of polypore diversity and natural history. We integrated over 40,000 historical and modern records of polypores in Estonia (hemiboreal Europe), revealing 227 species, and including Polyporus submelanopus and P. ulleungus as novelties for Europe. Taxonomic and conservation problems were distinguished for 13 unresolved subgroups. The estimated species pool exceeds 260 species in Estonia, including at least 20 likely undescribed species (here documented as distinct DNA lineages related to accepted species in, e.g., Ceriporia, Coltricia, Physisporinus, Sidera and Sistotrema). Four broad ecological patterns are described: (1) polypore assemblage organization in natural forests follows major soil and tree-composition gradients; (2) landscape-scale polypore diversity homogenizes due to draining of peatland forests and reduction of nemoral broad-leaved trees (wooded meadows and parks buffer the latter); (3) species having parasitic or brown-rot life-strategies are more substrate- specific; and (4) assemblage differences among woody substrates reveal habitat management priorities. Our update reveals extensive overlap of polypore biota throughout North Europe. We estimate that in Estonia, the biota experienced ca. 3–5% species turnover during the twentieth century, but exotic species remain rare and have not attained key functions in natural ecosystems.

    Anthropogenic N deposition increases soil C storage by reducing the relative abundance of lignolytic fungi. Elizabeth M. Entwistle, Donald R. Zak, and William A. Argiroff. Ecological Monographs. APPENDIX S3 Table S1. Agaricomycete taxa excluded from our list of “highly lignolytic taxa”. We excluded any classes, families, or genera: 1) that are known to be (largely or entirely) comprised of non-saprotrophs or for which the nutritional modes are unknown, 2) for which we have no information regarding a role in lignin decay, 3) for which there is published evidence that the taxon is either nonlignolytic or weakly lignolytic, 4) that are or may be lignolytic, but for which there is insufficient evidence that they are highly lignolytic, 5) for which existing evidence regarding their capacity to decay lignin is contradictory, 6) that are represented in our data set by fewer than 20 sequences regardless of their physiology, 7) that were “unclassified” at the order or class level (most not shown below), 8) that were “unclassified” at the genus level (not shown below) and did not belong to families selected as “highly lignolytic taxa” (see Table S2). We list the current (to the best of our knowledge) taxonomic placement of any taxa we excluded. If this differed from the classification we obtained from the Ribosomal Database Project fungal LSU rRNA v7 classifier (Liu et al. 2012) files, we documented this in the notes column.

Results indicate Gomphus s.l. to be non-monophyletic, leading to new combinations and the placement of its species into four genera: Gomphus sensu stricto (3 species), Gloeocantharellus (11 species), Phaeoclavulina (41 species), and Turbinellus (5 species). Key words – Fries, nomenclature, Persoon, systematics Introduction Gomphus sensu lato (Gomphaceae, Gomphales, Basidiomycota) is characterized by fleshy basidiomata that can have funnel- or fan-shaped pilei with wrinkled, decurrent hymenia. The genus, which was described by Persoon (1797a), has undergone several taxonomic and nomenclatural modifications over the past 200 years. The taxonomy ofGomphus s.l. (Gomphales) has proven difficult because of the few reliable morphological characters available for classification. Consequently, species of Gomphus s.l. have been classified under Cantharellus, Chloroneuron, Chlorophyllum, Craterellus, Gloeocantharellus, Nevrophyllum, and Turbinellus. A few species are mycorrhizal (Agerer et al. 1998, Bulakh 1978, Guzmán & Villarreal 1985, Khokhryakov 1956, Kropp & Trappe 1982, Masui 1926, 1927, Pantidou 1980, Trappe 1960, Valdés-Ramirez 1972).
