The second last one looks edible, but it's hard to tell with the terrible lighting conditions they were photographed under

Out in the sunlight, identifying mushrooms that have sprouted up through the night, will be easy if you have been shown by someone who knows

I was shown when I was a kid during early primary school, by a bloke who had a pie making store, we used to pick mushrooms for him, after a while he grew his own mushrooms in the back of the shop. You could see all his pie making going on through the shop front window, very transparent business, all on show for anyone who cared to peer through the large window. Everyone of his pies was a great tasty meal in itself, and a good variety, including mushroom of course

My secret is to target in on the only mushroom that I know is edible and non poisonous, I don't second guess, there's only one I look for, flat top with light brown gills, they can have a rounded top but they must be brown underneath. They are common where ever I've been in my travels, so are the poisonous mushrooms. You've got to know the difference

The lady in question couldn't have bought those mushrooms she cooked from the supermarket, so that leaves either picking them out of the ground, or they were given to her by someone

As Geoff said, the plot thickens
