I started out as a hobby mycologist but I live in Canada and mushrooms can be in short supply during the winter. I took up amateur lichenology to fill the void but I quickly became consumed by them, there was so much I didn't know and the uncharted-territory aspect of it took hold of me. Now I photograph way more lichens than mushrooms and I've started to do a bit of public speaking for my mycology group on lichens and their ecology. I am just an amateur though so I'm not an expert by any means. Pic: Stereocaulon sp. The link is below.
This guy misunderstood and now he's very angry at you. I suggests hiring adventurers for protection.
