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.
I would need to see the stem and gills to be able to identify it as even though it is a striking red there are a few possibilities.
Stem was thick and white and gills were also white, if this helps?
would guess a russula but as fenwickfield says really need more characters to go on.
