The RHIZOPOGONACEAE family includes hypogeous fungi gasteroid fungi called ‘false truffles’. These are in the basidiomycota. The true truffles are mostly ascomycetes. Like other gasteroid fungi, they have lost the genes involved with the forcible discharge of their spores. In general, the spores undergo maturation within a protective sack. When ready for dispersal, the fruitbody emits odors to attract burrowing animals such as squirrels, chipmunks and such to dig out and consume them. Fertile spores may end up in a relatively favorable environmnet with plenty of moisture and food from which to draw life and support continuation of its species. The protective covering of undiscovered hypogenous fungi disintegrates into the surrounding substrate.  However, soil microorganisms as well as worms and insects may also function as important spores dissemination vectors.
