The rhizines look right to me. See how they are sort of matted and woolly? That is very typical for the species (at least as I’ve been taught by Trevor Goward). Also note how the margins are ascending. In P. canina, for example, which has the same rhizines, the lobes are still concave like this, but they curl down right at the margins. This species has particularly thick thallus, as well, which you can sort of see at the margins.
