Black truffles are a unique type of fungi that are highly prized by chefs and food enthusiasts throughout the world. Which characteristic is seen in truffles but not in common mushrooms?

Black truffles are ascomycete fungi, which produce their spores inside saclike structures called asci (singular: ascus). Common mushrooms are typically basidiomycetes and produce spores on basidia. Both types have hyphae and reproduce, so the distinctive characteristic is having spores contained in an ascus.
