Lifelong naturalist, 20-year career as a biologist/botanist on the Central Coast of California. I'm currently studying lichens as a "hobby", and am assisting the R.F. Hoover Herbarium (OBI) at Cal Poly SLO with managing their lichen collection. Will happily accept lichen specimens from just about anywhere, but my focus right now is rock crusts in San Luis Obispo County and surrounding environs.
