Yeah, some are rather more obscure though, I chose that image because it's pretty much the closest match in terms of shape while also showing the very clear differences in skin smoothness and structure. Some may be significantly more dogeared and there are variations in breed(or whatever that term is). As I said research things properly to get a wider idea of the variations.

Also, when out hunting for this kind of thing you inevitably come across thousands of other types of fungus and mushrooms out there. Many of which are in fact edible and very tasty, I was with a girl a few years back who's dad was a fungal expert (forgotten the term now) for the local green part of the council and he used to collect hundreds of different types in an hour trip outside his front door (they lived in country surroundings). They did need preparing though and not all were edible straight from the ground. It's actually quite cool stuff though and knowing what you can and can't eat is unarguably a useful skill should you ever find yourself in a pinch.
