Very large (the size of a dinnerplate) striking white fungus. Earlier in the week the fruits had smooth, entire edges. Funnel shaped.
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.
Were they yellow as shown in the photos or white?
When young they were more creamy white - not yellow. They yellow is an artefact of the camera colour balance being set for an overcast day.
