Hi Mark
Just running this quickly off the top of my head without any cross referencing.
Top pic... don’t know
Middle pic... back left, Cep (boletus edulis) front left, clouded clitocybe (clitocybe nebularis).
Bottom pic.. sulphur tuft
Cep... excellent after drying/rehydrating to concentrate the flavour. Can be eaten raw or cooked from fresh but it’s bit tasteless that way.
Clouded clitocybe... listed in some books as edible, others claim it causes gastric problems. I read in an Italian book it causes brain damage unless either boiled twice with a change of water or first dehydrated then boiled.
Sulphur tuft... poisonous, causes severe gastric problems, reportedly can be fatal.
One place to start for id purposes
http://www.rogersmushrooms.com/ Have a go at the easy key. Would also be worthwhile checking out a couple of books to take with you on field trips.
Just a note, the sulphies look a bit past their prime. In order to reduce the chances of mistaken id it sometimes helps to look at fruit bodies of varying stages of their development (thinking of the belly-acher cortinarius purpurascens. Young specimens look very much like a wood blewitt, older fruitbodies look nothing like).
Good luck
