of the big difficulties trying to determine a blue Leptonia, that’s why you can’t trust other pictures on the web, and the reason to choose only a “could be”.
It keys out rather well as atrocoeruleum, with the dark blue colour, spore shape (4-7 angles), non-striate and fairly smooth cap with very small scales, and the stem that also has some small dots/scales. The gills are white from the start, and don’t get dark edges. The gill edge should be fertile, lacking the large amount of cheilocystidia that some other lookalikes have.

If it is the gill edge that can be seen in your micro shot, and the spores are within 8-12 × 6-8 μm, I might change my vote to “Promising” :-)

i was discouraged from collecting these on account of the vastness of blue Entoloma found in California and often how excruciating it is to identify them to sp.

on what do you base E. atrocoeruleum?
