for the most part the pleurocystidia in P. petasatus and P. cervinus are more or less the same.

Usually P. petasatus has a lot of unhooked metuloids near the lamella edge while in P. cervinus the metuloids near the edge are more variable and with no predominant shape.

Are the pleurocystidia of P. petasatus distinguishable from the pleurocystidia of P. cervinus?

Thanks Alfredo!

size of the basidiocarps, the colors of the cap and the squamose center suggest Pluteus petasatus
