(chiefly col.), col. map ;28 cm +1 CD-ROM (sd., col. ; 4 3/4 in.)General technical report PNW ;GTR-772"April 2009."CD-ROM includes a PDF file of the publication, photographs of 111 truffle species found in the Pacific Northwest, and a short movie produced by Daniel Luoma that features James Trappe demonstrating how to find truffles.Cover title.Includes bibliographical references (p. 165-194).Forests of the Pacific Northwest have been an epicenter for the evolution of truffle fungi with over 350 truffle species and 55 genera currently identified. Truffle fungi develop their reproductive fruit-bodies typically belowground, so they are harder to find and study than mushrooms that fruit aboveground. Nevertheless, over the last five decades, the Corvallis Forest Mycology program of the Pacific Northwest Research Station has amassed unprecedented knowledge on the diversity and ecology of truffles in the region. Truffle fungi form mycorrhizal symbioses that benefit the growth and survival of many tree and understory plants. Truffle fruit-bodies serve as a major food souce for many forest-dwelling mammals. A few truffle species are commercially harvested for gourmet consumption in regional restaurants. This publication explores the biology and ecology of truffle fungi in the Pacific Northwest, their importance in forest ecosystems, and effects of various silvicultural practices on sustaining truffle populations. General management principles and considerations to sustain this valuable fungal resource are provided.Also available via Internet.Mode of access: Internet.MycorrhizasNorthwest, Pacific.TrufflesConservationNorthwest, Pacific.TrufflesNorthwest, PacificIdentification.TrufflesEcologyNorthwest, Pacific.TrufflesNorthwest, Pacific.Trappe, James M.Pacific Northwest Research Station (Portland, Or.)Diversity, ecology, and conservation of truffle fungi in forests of the Pacific Northwest194 p.(OCoLC)36929028000742626420100105095926.020111213000000.020120815122756.02026-02-24T19:08:28Z2026-02-24T18:30:02ZSDR-UMNUNKNOWNloader.pl-001-001BKsdr-umn005459334umnSDRUMNumn.31951d02938269iUMN005459334UMNUMN20260224googleumn.31951d02938269i2009pdbibUS fed doc
