In my opinion photos 3, 4 and 5 are of panaelous cyansecens aka copelandia cyanescens, pans, cyans, blue meanies. Black spore print and the stereotypical presentation are the sealer for me. The printed one looks like a mature one that has begun to degrade. The fresh ones look like mature ones that have just dropped their spores over the last 1 - 2 days, depending on exposure to full sun.
Pics 1, 2 and 4 look like they are mainly cubes (hard to tell without being able to magnify them, even then...) with a fews pans smattered around. Check out this post (about half way down the page at least) I made a while back to help confirm by comparing my descriptions of the environs and conditions that are IME conducive to finding them:
A couple of basic rules of thumb when trying to figure if it's a cube or pan (aside from obvious colour characteristics):
- Does it have a veil? Yes = cube, no = pan
- Does it have a thick stipe/stem compared to the cap? If it's a 70:30 cap:stem it's a pan. If it's a 60:40 to 50:50 it's more likely a cube.
- Does it bruise blue green or navy/inky blue? Blue green = cube, inky blue = pan.
They both can have just a hint of gold at the top/umbo, and I've seen quite few pans that would give cubes a run in the ID stakes, but with these further criteria you should be right. Cyans will usually fruit much earlier as well.
BTW if you can, snap them off at the base and leave the mycellium in the ground to encourage further fruiting.
