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
