These are essentially identical, except that H. inactiva is black on the interior surface (tear open lobe tips to expose hollow interior), and H. imshaugii is pure white throughout the interior. Also, H. inactiva is a maritime species (pretty strictly west of the Cascades), while H. imshaugii is widespread throughout the region, both sides of the Cascades.
