MSSF Meetings

On the third Tuesday of each month from September thru May, the Mycological Society of San Francisco has a General Meeting at the Randall Museum.
The highlight of each meeting is a speaker with slides on some aspect of mycology and mushrooming: ecology, taxonomy, mycophagy, sociology, etc. Before each meeting members bring collections which are put on display and identified. Refreshments are served before the meeting. Doors open and identification starts at 7 pm and the meeting starts at 8 pm. (The December meeting is replaced by a dinner at a different location.)
Note: All regular General Meetings are open to the public.

  • Cat Adams
  • The Chemical Ecology of the Death Cap Mushroom

Cat's presentation will discuss how chemical ecology influences interactions between plants and fungi.

Amanita phalloides is an invasive ectomycorrhizal fungus. The death cap mushroom kills more people than any other mushroom, but how the deadly amatoxins influence its invasion remains unexplored.

Cat Adams earned her BS at the University of Washington, in Biology, with emphasis on Ecology and Evolution. As an undergrad she worked in Joshua Tewksbury’s lab, studying why wild Bolivian chili peppers produce spice. Cat then earned her Master’s degree at Harvard University in Anne Pringle’s lab, researching the fungal pathogens of wild chili peppers, and how the fungi evolved tolerance to spice.

Now earning her PhD at Berkeley in Tom Bruns’ lab, Cat is studying the invasion ecology of the poisonous death cap mushroom, Amanita phalloides.
In addition to her research, Cat is passionate about communicating science to the public, and has written for Slate and BBC Earth. She was the Communication Chair of the Mycological Society of America Student Section for two years, and is the President and Founder of the Unconscious Bias Project at Berkeley.
