I'm sorry for the late reply, and thank you both very much for your comments! Looking at the description, it seems to match quite well, but as it was already pointed out, the distribution is unusual.
I doubt I'll have much time at the end of May, but if I happen to get the chance, I can try to look for some specimens of the actual R. chrysopilaeformis in Valle del Tennacola (now called Valle dei Tre Santi, if I'm not mistaken). I'm sure it'll make comparisons easier.
