Ron Pastorino, retired in Marin County and a former chemist, is now all about the scientific fun (!) to be had hunting for and finding all sorts of fungi, photographing them in situ, taking them home, getting spore prints, making slides, and attempting to identify them.
If Ron is one of the foray leaders or co-leaders do ask him about mushroom microscopy as well as just any questions about mushrooms too.
He is considered very knowledgable in Bay Area and Sierra fungi.
