Will Rise Once More

The final answer to the mystery of the vanished fungoid society turned out to be fairly straightforward. The planet's population is not lost at all! They're still there, gestating underground. Analysis of an uncovered pod indicated that the species' centuries-long active lifespan was nothing compared to the pod-state gestation, which seems to go on for a few thousand years. Their simple cities, built to withstand long neglect, stand silently, awaiting their return. So, there they all are, slumbering in the ground, awaiting the day when they'll rise and start the cycle once more.
