Yeah, fungi a lot of times can be hard, and sometimes getting down to species level can involve knowing what tree species they grow with, what they taste like, or what the spores look like under a microscope LOL
I’d suggest searching up some good online information guides, or even buying some ID books, if you really want to get in to fungi - for online resources, Mushroomexpert.com is fantastic, as is the bolete filter (for boletes.)
Bookwise, the bible is Mushrooms Demystified by David Arora, and then generally it can be good to pick up field guides for your area.
