Mushrooms available in the rain forest right now are yellowfoot chanterelles, hedgehog, black trumpet, cauliflower, and some wood growers like bear's head, maybe still some oyster. Chanterelles are just about done and the ones left are gnarly and water-logged. The yellowfoot will always be damp because they grow mostly in moss. Use a salad spinner to shed some of the excess moisture. Commercial purveyors use a dedicated washing machine on the spin cycle.
Get two David Arora books: All That the Rain Promises and More (great field guide), and Mushrooms Demystified, by many considered to be the bible of fungi foraging in N. America.
