Notes:
Large (5-7 × 5-6 mm) apothecia fruiting mostly singularly from a well decomposed, decorticated hardwood log. Hairs on underside of cup, multiseptate, some very long, most bi-tri-furcate at base but appears some are unbranched. Spores ellipsoid, ornamentation of large warts, hyaline. Asci cylindrical, 8-spored, unitunicate. Paraphyses extending a little farther than asci, slender with apical thickening, measuring 6-8 um across.
Spore measurment:(17.3) 17.6 – 21.4 (23.1) × (12) 12.7 – 14.3 (15.1) µm
Q = (1.2) 1.3 – 1.6 (1.7) ; N = 19
Me = 19.9 × 13.5 µm ; Qe = 1.5
Asci measurement:(234.1) 242.6 – 285.2 (286.1) × (16.5) 18 – 24.5 (25.2) µm
Q = (10.2) 11.3 – 13.9 (15.9) ; N = 7
Me = 258.8 × 20.3 µm ; Qe = 13

In that case I would be happy with S pennsylvanica.

but it looks like the warts are flattened, and some coalesce, but many stand individually.

It is difficult to see from the photos but you may have seen better through the scope, do the warts have interconnections?
