The colours of the gills and stipe are better seen in the photos below. The stipe is clearly flushed pink, sometimes it's more lilac or purple, sometimes it resembles raspberry ripple ice cream.

Gills adnexed to slightly decurrent, narrow, at first a primrose colour that ages pale golden yellow.
Stipe 30-80mm high/10-15mm wide; sometimes white, often lilac to grey rose. There's a distinct primrose colour in the examples below.

Flesh white; taste very hot, smell slightly fruity.
