Arachnopeziza

Greetings,
I am curious on your opinion if you think this could be A. aurelia.
Fruiting from Quercus wood, Pennsylvania, USA, on 3-31-2020.
Subiculum is minimal, white and sparse, hyaline. Largest apothecium ~2mm but most smaller. Hairs ~15Oum and septate. IKI +. Crozier +. Medullary excuplum looks textura intricata, closer to edge some ectal more agularis. Paraphyses filiform, septate. 8-spored, ellipsoidal, mostly 3 septate but some only 1. Spores in H2O appear to have appendages but not in 10% KOH or lactophenol blue, maybe they dissolved?
Spore measure in H20:
(13.1) 16 - 20.5 (21.6) × (3.1) 3.6 - 4.2 (4.3) µm
Q = (3.6) 3.9 - 5.5 (5.8) ; N = 10
Me = 18 × 3.9 µm ; Qe = 4.7
I have the specimen inqubating now, any suggestions or ideas are welcome.
Thank you,
Devin

Re : Arachnopeziza
Surely it is. The appendages are typical but easily destroyed with chemicals.
