Inherently, they are punk.” That’s artist and designer Bella Lalonde—founder of the fashion label Beepy Bella—writing about her longtime love of mushrooms. In collaboration with Nautilus, Lalonde created a combination zine and foraging guide, [Mushroom Punks](, after an outing with fungi expert Bat Vardeh in the mountains of southern California. Inspired by mushroom hunting field guides of the past, [Mushroom Punks]( chronicles their excursion, weaving together photos taken by Lalonde, Vardeh’s expert commentary, and an illustrated catalog of the fantastic fungi they discovered along the way.

He based his bank in Leningrad, never dreaming that a massive famine would cause that bank to be in mortal peril. Thanks for reading! What did you think of today's note?
