Daphne Stone will be teaching a class at the beautiful SFI facility, April 21-23. We'll cover three difficult genera: Melanelia s.l., Bryoria and Peltigera. I'll bring examples of different species and we will practice chemical tests on Bryoria and Melanelia. We always go on field trips to see the lcihens in their habitats. If interested, sign up through Siskiyou Field Institute.
