Honey Mushroom

For example, you can see that under the older mushrooms there are other growing and they have some white spores on them. This would be one of the differences. Another would be the color, in Pholiotas the color is more bright, with a lot more yellow, as Armillarias have a more brown-pink color, in the last part of their lives they can turn even dark brown and the white spore imprints are more evident.
In the gills there are the same color difference, I mean that the Armillaria has almost the same color as the cap, and the Pholiota has different colors (from yellow to darkish brown, depending on the species).
Armillarias usually have a ring on the stem (but this can disappear with age).

Thank you Corduneanu, I must defer to your expertise, but could you provide me with any key differences, so I do not make the same mistake?

Believe me, I pick this kind of mushrooms and eat them on each and every autumn. If these were Pholiota, I could not eat them as they are not edible.

It is my understanding that armillaria have primarily smooth caps, could you clarify?

These are Honey Mushrooms - Armillaria Mellea.
