Our advantage is that our main company King of Mushrooms has over twenty years of experience in the sales and distribution of truffles. We offer inoculated truffle trees from nursery suppliers with proven success. Then we work with independent laboratories for a examination of tree health, root colonization levels with desired truffle species, followed by DNA analysis to confirm the trees are free from contaminants such as Tuber brumale and Tuber indicum. Our nursery suppliers offer five prized truffle species (Black Winter Truffle - Tuber melanosporum Vittadini, Black Summer Truffle - Tuber aestivum Vittadini, Black Burgundy Truffles - Tuber uncinatum Montecchi & Borelli, Black Autumn Truffles - Tuber macrosporum Vittadini and Spring White Truffles - Tuber borchii Vittadini) Our goal for Autumn of 2018 is to offer the most prized truffle in the world (The Alba White - Tuber magnatum pico).

Organic Solutions

The leading causes of truffle tree mortality for California truffle cultivators is due to gophers and squirrels which chew off the trunk of the tree from the roots, killing the tree. California Truffle Orchards (CTO) offers multi-fasted organic solutions to control these pests.
