This is exactly what you want. Fungi are breaking down your buried logs and when they finish what they can use, they send up mushrooms to release spores and complete the life cycle. You may get another flush of that particular species, but when they run out of "food" you won't see them again and another species will pop up. It may take several species to completely break down the biomass in the logs. And all that mass that the fungi are breaking down becomes nutrients to feed the bottom of the food chain.
If you are wondering what to do with those mushrooms, if you have enough and they are of a suitable species, you can serve them for dinner. But only if you are triple sure on the identification. If you aren't 300% sure, then use them to inoculate new piles of brush, logs, and wood chips; blend them up with some water and pour them liberally all over the stuff you want to rot.
