the top picture is inky caps.
the middle and bottom pictures are shaggy manes.
Shaggy manes also turn black and make black slime as they get older.Shaggy manes are best eaten before the cap opens up.I think shaggy manes don't taste great,even with butter but they can be eaten.Alcohol should not be drank within 24 hrs either way of eating these mushrooms or they make you get a crappy hangover!
Be careful eating mushrooms from areas like parks and ditches which are often sprayed with chemicals.
Also,never eat a mushroom you are not absolutely sure of its identification,many look alike and are difficult to identify by looking at the fruitbody alone.
Some types of mushroom poisons can start having effects within an hour of ingestion but most of the worst poisons take about 12 hrs before they start destroying your liver and kidneys.There is even a poison that takes 3 weeks to cause problems,who would even think about something they ate so long ago as being the culprit?
Shaggy manes are one of the easiest mushrooms to identify,many even the experts are unsure of their properties!
