Aloha & Welcome to Hawaii’s Extraordinary Specialty Mushroom Grower


Hamakua Mushrooms are a specialty and exotic mushroom, grown in a substrate of corncob, wheat bran and saw dust.  Our mushrooms are carefully cultivated to grow out of a bottle, a method originally developed in Japan.   The bottle cultivation method is how Hamakua Mushrooms  developed their signature “Ali’i” mushroom, a 3-½ inch mushroom that has a thick, meaty, one-inch-in-diameter stem.  In keeping with sustainable farming methods, Hamakua Mushrooms recycles the substrate and sells to farmers across the island, this rich mixture boosts their crops growth.
