Can anyone id this small agaric emerging from a nearly dead sweet chestnut trunk? No smell I could detect and no milk from the stalk. Pretty dense woodland on sandy soil.
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.
This looks very much like M galopus to me. Another possibility is M polygrama which has a ridged stem, like this find.
