ID a decent fit.. But I cannot find if the hairs on the underside are consistent with this genus/species. Whatever it is - it's Somewhat common on fallen logs. Olive green to yellow tones peeking through in aged specimens, along with micro and a similar sequenced obs has me thinking this genus.

Spores:
(6.2) 7.1 - 8.7 (10.1) × (1.7) 1.75 - 2.8 (3.1) µm
Q = (2.7) 2.9 - 4.4 (5.4) ; N = 10
Me = 7.9 × 2.4 µm ; Qe = 3.5
Asci with I+ apical pore
(77.4) 78.8 - 84.9 (87.5) × (3.7) 4.3 - 5.3 (6.2) µm
Q = (12.7) 15.6 - 18.9 (20.8) ; N = 8
Me = 82.3 × 4.9 µm ; Qe = 17.3

Tuber sp. collected on surface of soil in flood plain. Likely washed up in the flood.

Found and collected by @Brennons
Growing on Marchantia polymorpha or Conocephalum. I didn't think Marchantia had black streaks like this, but gemma cups were present on this wall of liverworts like Marchantia.

With some orange sebiculum like hyphae surrounding short spines of up to 3mm long. Growing on an upturned Ulmus americana, but seemingly from the soil, no attachment to wood visible though it's possible rhizomorphs were running to connect to rootlets.
Hydonoporia? Sarcodontia or Mycoacia?

Dimitic,
Spores remaining brown in Melzers. Strongly ornamented and warted.
(6.8) 7.4 - 8.3 (8.6) × (5.8) 6.2 - 7.5 (7.7) µm
Q = 1 - 1.25 (1.3) ; N = 30
Me = 7.8 × 6.8 µm ; Qe = 1.1

Basidia 5.8 - 6.2µm wide.
Skeletal Hyphae regularly clamped and septate, 2.1 - 4.5 µm wide.

R. palmatus is the name that could be applied, but sequence data indicates there is at least one other Rhodotus in the midwest. On the butt of a cut fallen tree in Carya, Ulmus, Quercus area. Same fruits as in this observation.

Spores often truncate.
(24.8) 27.5 - 34.2 (37.4) × (11.5) 12.1 - 13.3 (13.5) µm
Q = (2) 2.1 - 2.7 (3) ; N = 15
Me = 30.9 × 12.8 µm ; Qe = 2.4

With large guttles at the poles averaging 5um in width. Smaller guttules present.
