Recognized by sight: Reminds of S. glaucopus, but more pinkish colour on the cap, and more bitter taste. The spines are not quite that decurrent, instead they become wart-like down the stem. That fits the first picture, but not the second. Are they really the same?

if we are using the same name on different species. But that wouldn’t be the first occasion..

Spiny stipe

They are the same, although the spiny stalk may be abnormal; a few had stalks covered with spines, but most curved with the spines on the underside of the curve.
Looking at descriptions and images online it looks like the European S. scabrosus, but not what we have been calling scabrosus here…
