around cervinus have these hooked cystidia. P. pellitus is one of them, with a whitish cap (petasatus is another). To complicate things, many Pluteus species, including cervinus, occur in white forms. But this time, I think pellitus is a good choice.

Looks like Pluteus pellitus with slightly bigger spores.

Do all Pluteus species have apical projections on the cystidia? I know P. cervinus does, but have not read much about the other species.
