this seems to be Ch. fulmineus which is not rare in Southern Europe and where I live (thermophilous mixed forests but mycorrhizal with Pinus). The margin of the cap shows the typical remnant of the violet veil also very slightly visible on the upper half of the stipe. The color of the cap is more vividly reddish orange than in rutilus. What I do not see in the pictures is the flesh turning greenish in the base of the stipe which is also a good distinguishing criterion between fulmineus and rutilus. There is a third species called Ch. testaceus but I am not sure if this is a good one. Here Melzers Reagens would help which shows green to black discoloration when applied on cap and stipe context in fulmineus whereas it stays nearly unchanged in testaceus and rutilus. Confer my observations of these species too.
