This talk focuses on the incredible biodiversity of truffle species that have been uncovered in the Sierra Nevada foothills as part of a local fungal biodiversity survey project. Truffles are an extremely diverse yet understudied group of organisms. Many fungi spread their spores through the wind by producing mushrooms, which are spore-producing structures that occur above ground. Truffles, on the other hand, are fungi that have evolved to produce their fruiting bodies completely underground. Come and learn more through this presentation and the Q & A afterward.
