Looked like a bracket fungus but was in open grassland. Other fungi in same area.
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
There might be a stump or root under the grass that has started rotting.
It would be worth lifting it to show how it is connected to ground and what sort of gills it has...
