- good to know the building's not moving, eh?
I prefer Roger Phillips' huge tome 'Mushrooms' which (after 25 years in print!) has just been re-published with extra species & new common names. About 1250 in all - BUT his photies are excellent and there's a great visual guide at the start for edibles, toxics & specifics like brackets...It's a bit smaller than the other Roger Phillips guides too, although about an inch thick. I got a signed 'Wild Food' too - used a recipe from this recently with beefsteak fungus (first time!) - bloody gorgeous! Best foray meal in a long time...
The info's all on the web too (for you electro-bushfolk with your gadgets...or to check when you get home...) but the pics are too small for me. Still, give you an idea of what the book's like, and it's free. See

ISBN: 0330442376 for the new edition. Looks like you can get it for around 12 quid plus postage. Seems the old editions are about the same price.
As for field guides - I don't bother myself. I spend too long peering at little pictures or wading through dichotomous keys and getting lost in Latin...and I prefer to learn now, eat later...so I take what I can (if there are enough specimens not to jeopardise future generations and to fill my belly if edible).
Once back to base, I scrutinize until I get the ID. If I'm 100% certain it's edible (it has to be 100% for me - no taste tests or magic sixth sense here) I get to work in the kitchen. Then I make sure I use my knowledge when out & about in future. It keeps my books clean and saves my temper too...
By the way, I went on two forays with the same expert, and he turned his nose up at the beefsteak - I grabbed it quick and what a prize! He reckoned every 'hunter' has their top 10 edibles, and generally ignore edibility in others. They're really only in it to catalogue & discover new data with the odd meal as a reward, whereas I simply want to stuff my face!
Also, about sporeprints - sometimes the mushrooms have already made them in situ! Look at the area directly underneath the gills / pores without picking the things and you may see spore colour. I've seen it on caps growing under other caps, although you'll have to look close if you want to distinguish pink from white!
Handy hint 2: when making sporeprints place the cap with stipe removed on half white half black surface. That way you won't miss any spore colouring.
Not checked it out yet, but apparently this book "Mushrooming Without Fear" by Alexander Schwab ISBN: 1873674880 describes ALL you need to know about the tasty edibles so you'll be in no doubt whatsoever about the edibles, and dispose of the others. At least that's what it claims. I might get it soon but spent too much this month...
Phew! Hope this helps along with the other excellent advice on this thread!
Cheers & good hunting
