It reminds me more of some Antrodia or Diplomitoporus flavescens …

They are rather Fomes-like on the upper side, but the hymenium reminds more of Fomitopsis or Heterobasidion annosum (rarely hoof-shaped). The latter is easiest recognized by a strong reaction with Melzer’s (dextrinoid).

Does Fomitopsis officinalis occur on Jack pine..?
