British Columbia Ectomycorrhizal Research Network
Ectomycorrhizae Descriptions Database
The Ectomycorrhizae Descriptions Database (EDD) system was completed in August 2007 and updated and migrated to a new web service in 2024-2025. The system was developed with the purpose of bringing together as many published and unpublished ectomycorrhizae (EM) descriptions as possible, and to be a comprehensive tool for identification of ectomycorrhizae.
Objectives
- To promote conservation of the diversity of ectomycorrhizal fungi
- To facilitate ectomycorrhizal research
- To facilitate the use of ectomycorrhizae in sustainable forest management
Scope
As of August 2024 EDD contains 557 descriptions in total, including 318 from Determination of Ectomycorrhizae (DEEMY) (1993), 39 from a Manual of Concise Descriptions of Ectomycorrhizae (CDNAE) as well as 200 unpublished descriptions from the Photoprofiles of Ectomycorrhizae (POE). EDD can be searched either by browsing a catalogue of EM types in the database or by a synoptic search of key features and characters. The catalogue and search results page also provides links to images in either CDNAE or POE, and to GenBank for those EM types described in CDNAE or POE for which DNA sequence data have been accessioned, to the DAVFP herbarium accession number for accessioned EM specimens, and to the database from Matchmaker: Mushrooms of the Pacific Northwest if a description of the mushroom of that species in EDD also occurs there. EDD was first published online in 2008 and is a revised version of the earlier Database of Descriptions of Ectomycorhizae (DDE), completed January 2000 and removed in March 2006 because of legacy software issues.

Contributors
The earlier Database of Descriptions of Ectomycorhizae (DDE) system was developed by Doug Goodman, Stephen Barker, Alan Thomson, J.A. (Tony) Trofymow, Dolim Chow, Chris Geoghegan and Norman Sim.
R. Agerer is acknowledged for his permission to use the DEEMY data in the database.
Funding
Funding for the DDE had been provided by the Biodiversity Network of the Canadian Forest Service and by the BC Forest Research Extension partnership (FORREX).
Funding for development of EDD came from the BC Forest Investment Account: Forest Science Program (FIA-FSP) and the Canadian Forest Service.
Updates to EDD in 2024 were funded through the Canadian Forest Service ForSite program.
