Doesn’t have serrate gill edges, and the one you linked to appears to have had a veil, and overall looks a bit more like Pleurotus dryinus.

And if you look at the second photo on ‘full size’ you can see the gills aren’t serrate. Unless they are 10 micron serrations…

odor sometimes not such a great way to tell what you have…

Clitocybe gigantea has been described as pleasant, slightly disagreeable, farinaceous and “like fish.” Pleasant could be misconstrued as sweet/anise.

Lentinus levis is described with a citrusy not an anise odor (altho the rest certainly fits).
And of course some Clitocybes do grow on wood.

Toughness of fruit body and serrated gills should confirm. It does look an awful lot like this example of Lentinus levis from the SE:


Lentinus levis looks like a good fit.

it is yellow and was fruiting from a hardwood stump, and that species (which is a Leucopaxillus) smells farinaceous, not like anise.

There is also L. suavissimus to consider with a strong anise odor (and supposedly funnel shaped), but I have heard a couple different folks compare that of L. levis to anise, although it has also been called ‘citrus’ in field guides

was the fruit body soft or tough?

did you see serrated gills in the field? they don’t look serrated in your photo here…also the cap isn’t scaled like a Neolentinus, and the base doesn’t appear to be rooting.

IF a Clitocybe, why not C. gigantea? It’s certainly big enough…

Probably not…

I just remembered that Lentinus levis ages bright yellow… this is one of the less fuzzy forms

no serrated gills…

prob. a Clitocybe after all.

too much green in that darned forest reflecting on a white cap?

Looks like Neolentinus…

But what’s with the chartreuse color in the first photo?
