What gear should you bring on a mushroom outing?

MycoWiki answer

Match the equipment first to the route and weather: footwear with reliable grip, protective clothing, water, a charged phone, an offline map when needed and a small first-aid kit. Tell someone your route when the terrain warrants it. For observation, bring notes, a size reference and a way to photograph without distorting colours. Use a firm, ventilated container when collection is allowed, and physically separate every doubtful specimen to prevent mixing. Remove only what is necessary for competent inspection.
