Sorry, forgot to comment on the photos! I like them, especially number 2. They look like a little family all huddled together. I know how difficult it is to shoot fungi. One tip is to get down low and try to shoot at their level. You can sometimes get a nice uncluttered blue sky or green field as a backdrop (but not in a woodland).
As for the ID. I would go on amazon and check out some used books. Its always best to have a couple to refer to. Or, if you are in a rural place - ask the old folk. They'll find you funny asking such obvious questions and in crappy Spanish should make things interesting.
I once had a huge wasp land on my bare foot in the jungle, and I asked the guide if they were dangerous and replied yes! I asked if they can kill you and he replied yes! I later found out that he didn't speak English and 'yes' gets positive responses so he says it to almost every question!
Happy foraging and photoing!
