We had several of these mushrooms come up in a raised bed that was converted into a wood core bed last year. This mushroom grows well on wood covered with dirt, so you should see it popping up in Hugel beds. It's edible, but not a common table mushroom.
Even with books, it is easy to get the wrong mushroom. Usually not deadly, often sickening. Work with an experienced friend or local mushroom society. There are a few that most people can identify from books: Turkey tails, shaggy manes, and a few others. They are often listed in books as 5 easy mushrooms, etc.
