David Arora Talk and Guided Foray/Tasting — October 22nd and 23rd 2010
David Arora, a prominent American field mycologist and author of “Mushrooms Demystified” and “All That the Rain Promises and More…” will be giving a talk at Lane Community College in Forum Room 308 at 7:00 PM Friday, October 22nd 2010. This talk is sponsored by CMS and titled “The Wheel of Fungi, Chapter Two.” The first chapter of the talk will be given a week earlier at the Yachats Mushroom Festival. The talk open to the public and the CMS is encouraging a small donation at the door.
David will also be leading a mushroom foray and tasting on Saturday October 23rd 2010. The location is still to be determined and will be within one hour of Eugene. This will be an all day event. The cost is $80, space is limited. Please call Joe Spivack @ 541-729-1248 to register in advance.

Fall Mushroom Foray Dates — First Foray October 10th, 2010
We have several foray dates coming up in October as the mushroom season unfolds. The first of these trips will occur on Sunday, October 10th. We will also have other forays in anticiaption of the Mount Pisgah Mushroom Festival on Saturday Oct. 23rd, Sunday Oct. 24th, and Friday Oct. 29th.
Forays are limited to CMS members (and friends) only. You can become a member on Sunday to join us! We plan on visiting the Siuslaw National Forest near Florence, dependent on weather over the next couple weeks. In the Siuslaw National Forest no permit is required for small quantities of mushroom collection, up to 1 gallon per person per day. Additional information on permits may be found on the Siuslaw National Forest website.
Meet at the South Eugene High School by 8:45 for introductions and directions. We will leave at 9:00am sharp.
Tricholoma Flavovirens Toxicology Research
Indications of hepatic and cardiac toxicity caused by subchronic Tricholoma
flavovirens consumption
P. Nieminena, V. Kärjäb, and A.-M. Mustonena
Food and Chemical Toxicology
Volume 46, Issue 2, February 2008, Pages 781-786
The confirmed finding of increased plasma CK activities and the novel observations of the present study – increased CK-MB activities, elevated plasma bilirubin concentrations and signs of pericardial inflammation – indicate that regular T. flavovirens consumption should not be recommended.
The results also enforce previous findings that the harmful effects probably require prolonged exposure and high amounts of ingested mushroom. In this context, occasional consumption of T. flavovirens would probably be harmless except in sensitive individuals, such as persons on medication, children or during pregnancy (see also Tofani, 2003).
Due to the findings of toxicity after repeated meals and controversy regarding the taxonomical position of T. flavovirens, the marketing of T. equestre (or T. flavovirens or T. auratum) was recently prohibited in Italy (Ministero della Salute, 2002), France (Ministère de la Sante et des Solidarites, 2004) and Spain (Ministerio de Sanidad y Consumo, 2006) and, in contrast to the situation after the first findings of toxicity (Korhonen, 2002), T. flavovirens is no longer considered edible in the most
recent Finnish textbooks (Salo et al., 2006).
5. Conclusions
(1) No morbidity or mortality could be detected in the mice consuming freshly frozen T. flavovirens at 12 g kg?1 d?1 for 4 weeks. (2) The exposed mice had higher plasma bilirubin concentrations and higher CK and CK-MB activities than the control mice indicating hepato-, myo- and cardiotoxicity. (3) Signs of hepato- or myotoxicity were not present in the histological samples, but the cardiac samples showed increased incidence of pericardial inflammation in the T. flavovirens-fed mice. (4) Repeated consumption of T. flavovirens should be avoided.
Amazon Mycorenewal Project
Between 1964 and 1992, Texaco spilled over 18.5 billion gallons of highly toxic waste into 600 open unlined pits. Little has been cleaned up. These pools contain a mixture of oil, heavy metals and radioactive substances that continues to overflow and seep into the water table, resurfacing in rivers and wells. 
The Amazon Mycorenewal Project brings this exciting technique to the Amazon for
the first time ever. A coalition of Ecuadorian and international non-governmental organizations is partnering with local people to remediate their lands using mycelium as well as grow edible and medicinal mushrooms for consumption and income generation.
Truffle Dog Training Sponsored by the North American Truffling Society
Noted dog trainer, Jean Rand, will lead the second NATS truffle dog training seminar at The Carriage House building, Benton County Fairgrounds, 110 53rd Street, Corvallis, Oregon, 97333 on October 10, 2010 from 9:00 AM to 5 PM. Jean and Gusto, Oregon’s most proficient truffle dog, have been featured in training seminars at the Oregon Truffle Festival and for NATS, as well as sought after to determine whether plantations are producing truffles. The seminar will be a combination of lecture, fundamentals of scent training and practical field work. Attendance is limited to six dogs and four audits. A waiting list will be maintained.
Fees must be paid in advance by September 30, 2010. All dogs will be required to be under handler control and well mannered in company of other dogs and people. Aggressive or disruptive dogs will be ejected from the class without refund. Beverages and Continental breakfast will be provided.
Dog and owner training ~ $185
Audit class, sans dog ~ $75

Matsutake Survey Volunteers Needed
The Deschutes National Forest, in conjunction with
, is conducting surveys of matsutake fruiting grounds to identify the impact of forest thinning. The American matsutake is a highly prized edible mushroom, the commercial harvest representing a multimillion dollar industry. Volunteers will help locate matsutake mushrooms and collect soil samples and field data. Matsutake have a symbiotic relationship with “candystick” plants (see below), which are used by volunteers and mushroom harvesters, to locate the mushrooms.
When: Mid Sept - Mid Oct

2010 Matsutake Survey Volunteers Needed
General Meeting — Thursday September 9th, 2010
Can you believe that fall is already fast approaching? Though the tomato vines are still laden with very green fruit, at least we have another fruiting season to look forward to—fungi. The Cascade Mycological Society holds its first general meeting Thursday, September 9th. The topic will be an introduction to fungi and fungi ecology. For those of you who are expert fungophiles, it is still a great opportunity to mingle and meet with other mycologically minded people—and to find out about fruiting in our area.
Meet at 7:00 pm, room 115, Science Building (Building 16) at Lane Community College in Eugene.
Meeting presented by Chris Melotti. See the complete slide deck for Poisonous and Hallucinogenic Mushrooms, by Michael W. Beug.
