  1. All Taxon Biodiversity Inventory . Fungi Great Smoky Mountains National Park ATBI AGARIC DIVERSITY IN THE GREAT SMOKY MOUNTAINS NATIONAL PARK PART OF THE GSMNP ALL TAXA BIODIVERSITY INVENTORY (ATBI)

  2. PROJECT GOALS • Three years of collections by experts in various groups of agaric fungi • Databasing of current and past collections • Bar coding of species using ribosomal ITS region • Species pages available on web

  3. TENN • Tennessee herbarium web site lists 1500 species from the GSMNP • Goal – to link to photos and records in next three years

  4. PARTICIPANTS Aime, Cathy – Rusts and Crepidotus Ammirati, Joe - Cortinarius Baroni, Tim – Entoloma Buyck, Bart – Russula / Lactarius Caranza, Julietta - Trametes Cifuentes, Joaquin - General Halling, Roy – Gymnopus and others Horak, Egon - General Kerrigan, Rick - Agaricus Lodge, Jean - Hygrophoraceae Mata, Juan Luis - Gymnopus Matheny, Brandon - Inocybe McCleneghan, Coleman - Pholiota Methven, Andrew - Lactarius Ovrebo, Clark - Tricholoma Tulloss, Rod -Amanita Verbaken, Anameka – Russula /Lactarius COVERAGE SPONSORS Karen Hughes Ron Petersen Ed Lickey Gymnopus – 450 sequences Collybia Omphalotus Artomyces (Clavicorona) Lentinellus Lentinula Xerula Ramaria Andrew Miller - Pyrenomycetes

  5. TWO PROBLEMS FOR BARCODING USING THE ITS REGION • PROBLEM 1 • INABILITY TO DISTINGUISH SOME APPARENT MORPHOSPECIES (GYMNOPUS SECT LEVIPEDES) • But – does distinguish a number of Gymnopus collections previously grouped as the same morphospecies (cryptic species)

  6. TWO PROBLEMS FOR BARCODING USING THE ITS REGION • PROBLEM 2 • THE ITS REGION IN COLLECTIONS FROM THE GSMNP HAS RELATIVELY HIGH LEVELS OF HETEROZYGOSITY FOR INDELS. • Requires cloning with its attendant problems

  7. Cortinarius sp. = 31.3% Lactarius sp. = 25.0% Hygrophorus = 57.7% Saprobes = 28.5%

  8. PROPORTION OF COLLECTIONS FROM THE GSMNP THAT WERE ALREADY REPRESENTED IN GENBANK • [98% CONGRUENCE WAS ARBITRARILY CONSIDERED TO BE CONSPECIFIC] • 159/533 MATCHED SPECIES IN GENBANK • 23/533 MATCHED UNNAMED ENVIRONMENTAL SAMPLES • 351/533 HAD NO MATCH IN GENBANK • FOR AGARICS, SEQUENCE COVERAGE IS STILL SIGNIFICANTLY INCOMPLETE

  9. GSMNP BAR CODING PROJECT? • Home of an ATBI • Center of Biodiversity • Highly varied terrain /ecosystems • Nice collecting spot • Good field station • On the ground help • Need I say more?
