Microscopic work by @jackjohnsonn below:
From a quick look into it, the margins of difference between descriptions of C. archeri and A. rubra are slight. C. archeri is described as having minutely shorter spores (one half a micron), and sphaerocysts of up to 5um smaller than those of A. rubra. That being said, the microscopy is consistent with C. archeri on both accounts.

Spores cylindric, hyaline, sometimes with guttules.
(4.5) 4.8 - 6 (6.8) × (1.6) 1.7 - 2.1 (2.2) µm
Q = (2.1) 2.7 - 3.1 (3.5) ; N = 30
Me = 5.5 × 1.9 µm ; Qe = 2.9
Sphaerocysts
15 - 36.4
Me = 25 um ; N = 25

PFLHI001 - 7 reproductive bodies of fungus identified as Coprinopsis pulchricaerulia. One group of two (one older, one fresher specimen), one group of three (two older and one newer), one broken from substrate with damage from something eating it, one small one also broken. Older mushrooms darker in colour, a blue green in the range #00628E while younger mushrooms are a lighter royal blue in the range #1B6AF9.
