Collection location: Point Reyes National Seashore, Marin Co., California, USA [Click for map]
This ID is a little shaky as the taste seemed mild to me and the stem was not as long as indicated in MD. However, everything else seemed to fit and Darvin has a similar looking observation from Point Reyes.
If so, I’d be curious about your results as I am digging down into similar Lactarius species such as subviscidus and substriatus. I’m most curious about the structure of the cuticle. Thanks!
