Reddit reviews Collins Gem Mushrooms: The Quick Way to Identify Mushrooms and Toadstools

The (SAS Survival Guide)[https://www.amazon.co.uk/SAS-Survival-Guide-Survive-Collins/dp/0008133786/] has some good survival information whilst not taking up much room in a bag. I also have this one for foraging and this for identifying mushrooms. In an emergency situation I'd say knowing what is and isn't edible around you is important. When I'm out I often use my phone to identify anything I am not familiar with and have a reasonable knowledge now but having the books to be sure seems sensible.

I have an air rifle which will take birds and rabbits if it comes to it too and whilst they have made it harder to get one these days (you have to order it to a licensed shop to pick it up and can't just order it to your address any more... and these stores are often few and far between) it does seem like a sensible thing to have. Not for self defence but for having access to a food source that most people would not have.

Besides that I don't think the information varies too much from what you find on US sites. Though the prices often do so you have to economise more than they would... likewise of course with the size of houses here compared to there. I don't have the same kind of space for stockpiling food and water as I would in the US.

Only pocket identification guides I know of are the Collins ones.

I'm sure that is a different edition to the one you had but it is pretty good.
