Mushroom ID Workshop

Saturday and Sunday, December 2nd - 3rd
or Saturday and Sunday, December 16th - 17th
with Naturalist and Mycologist, Mario Abreu

This year we are offering two opportunities to take this in-depth two-day workshop. Each session of Mushroom ID for Beginners consists of an interactive lecture (Sat) with demonstrations and an optional Field ID Walk (Sun) to find mushrooms associated with the Mendocino Coast Botanical Gardens' native plant communities. Naturalist and Mycologist, Mario Abreu will teach the basic taxonomic identifying features that distinguish mushrooms from each other, where each unique mushroom species can be found, when they can be found, and the myths associated with them. 

The guided walk is optional, class participants can also explore our wild mushroom collection on their own time armed with a list of species commonly found at the Gardens.



  • Saturday's Lecture will take place in the MCBG Farmhouse and Education Center from 10:30PM to 3PM with a lunch break from 12:30PM to 1PM.
  • Sunday's Field ID Walk will meet at the MCBG Farmhouse at one of three optional times 9AM, 11:30AM, or 2PM.
  • The class will include indoor instruction on Saturday and a guided field walk on Sunday. Be prepared for the weather with appropriate layers.
  • We recommend bringing along drinking water, a notebook, and a pen both days. Bring a sack lunch on Saturday.
  • Please read and follow our local Health Order. If you are sick, please stay home.
