The 2002 North American Mycological Association Foray

Oregon 2002

The 2002 NAMA foray was hosted by NAMA Northwest, and held at Diamond Lake, Oregon, October 10-13, 2002.

Dr. Jim Trappe from Oregon State University was the Chief Mycologist

NAMA Northwest

NOTE: Additional specimens and species records are being sent in to the Field Museum (April 2003) and the numbers below have not yet been updated.

Foray participants exceeded expectations by finding a bounty of mushrooms and other fungi despite the dry conditions and frosty weather. From the start of the weekend through Sunday morning the large maintenance garage at Diamond Lake Resort had been transformed into mushroom central with many tables for the sorting, display, and identification of fungi. At the end of several busy days 246 fungi had been identified for the 43rd NAMA foray, the first one to be held in Oregon.

Of the species and varieties recorded, 45 had not been listed for previous NAMA forays. This is 20%, or one-fifth, of the 227 total identified to species. This is not too surprising considering that, not counting 5 Idaho forays, there have been five west coast events, 2 California, 2 Washington, and 1 British Columbia. In addition, nineteen of the fungi had only been recorded from a single previous annual foray, and in all 19 cases these were western forays except for Tricholoma intermedium and T. magnivelare which were recorded for a North Carolina foray. At the other end of the spectrum Laccaria laccata and Pluteus cervinus once again made their appearances. These two species remain tied for most frequently recorded species. Both have been found on 32 out of 36 annual NAMA forays (of the 43 that we have lists for). Other frequent fungi found at the Oregon foray include: 28 forays - Trametes versicolor and Xeromphalina campanella; 27 forays - Hydnum repandum; 26 forays - Boletus piperatus and Scutellinia scutellata; 25 forays - Lycoperdon perlatum, Mycena pura, and Polyporus elegans.

Mushroom groups that filled the tables included boletes, Cortinarius, Ramaria, and truffles. One of the twenty Ramaria recorded is a probable new species. Of the twenty truffle-like fungi identified, seven are new to NAMA forays, and Jim Trappe found a Leucogaster to be a new, previously undescribed, species. The late fall weather also produced many Tricholoma and Hygrophorus. In the large category were a gigantic Hericium abietis hauled in by Henry Young (see link below), a big Catathelasma found by Patrice Benson, and many people found the large edible Matsutake (Tricholoma magnivelare) or the poisonous Amanita smithiana, which is in a new category of toxic fungi. There were many other notable finds including Laetiporus conifericola -- a new western conifer species of sulphur shelf, Cantharellus cascadensis -- the recently described western yellow chanterelle, and Orson Miller identified the rare white form of Cystoderma amianthinum.

Adding the Oregon foray list to the growing master list of NAMA fungi yields about 2,650 species and variety names for 36 annual forays. This continues a steady ascent toward a total of 10,000 species of macrofungi estimated for North America (Mueller et al. unpublished).

Jack Murphy and I thank all of the mycologists, volunteers, and students for helping make the recording and voucher process a success.
