I wouldn't bet on it, but it's hard to tell from the photos. Is there a network of fine lines (reticulation) on the stems? Also, check the taste; Kings are never bitter. The ones that I see on the coast have yellow tube mouths when old, white when young; and I've never found them under anything but conifers.
Yeah Vitog, they didnt taste bitter and the older ones had yellow pores and yes there is fine lines on the stem.
