A few of the wild mushrooms I eat are shown below, but not the very last one
Sulphur shelf or chicken mushroom
If you're far from field and forest, there is still hope for you. I frequently find lots of inky cap mushrooms right in town.
Get a field guide and use the web for identification. Understand that a few common edible mushrooms can cause an allergic reaction with some people, and poisonous mushrooms can cause a lot worse things than that.
One of my favorite quotes in reference to the edibility of amanita muscaria "though not usually fatal, it is an experience not easily forgotten."
