Mushroom I.d. Help please

[Newhunter]

Pretty much no aroma. Slight hint of typical grocery store white button aroma. Found on a decaying tree stump with three or four others within inches of it. The stem of this one was touching the stem of another.

Looks like Polyporus arcularius.

Neofavolus alveolaris --another small spring polypore-- has pores that are similarly elongated-polygonal. But this type is generally orangish and the short stalk is usually not centrally attached to the cap.
