There are dozens of good descriptions and hundreds of photos on the internet of panaeolus cinctulus (a.k.a. p. subbalteatus). It's a common species. Most of the mushrooms you mention are pretty arcane species indeed. I'd put my money on ps. cubensis, copelandias and perhaps pan. cinctulus.
However, the only way to get there, is to just get out and see what you find. Note the habitats you encounter and find out which species are likely to grow there. Then go out and look, and do it again, and so forth.
