Currently growing nicely in my garden.
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.
Not a word most people use when they have Honey Fungus in the garden.
Key identification features not clear, but I agree this is probably Armillaria mellea. Certainly an Armillaria species of some sort, and the dense clustering and what looks like a well-formed membranous ring suggest this species.
Where I work/worked we have them clumping, particularly by stumps & solitary ones or small troops probably following main tree roots.
