On rotten pine stump
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.
The surface spines appear to be sooty brown
could it be L. nigrescens?
Could be but was not totally convinced myself as thought L.nigrescens was darker but you could be right.
