This one's hard to pick from the photos. It is more likely P. calidirupium. The pinnae look like they're angled at 60+ degrees from the plane of the frond in some pinnae, and that's more typical of P.calidirupium
They look like they've had a tough time in the frost/sun as well... I wouldn't mind checking out the area in person and having a look first hand at them. Good find FranM.
