I don’t have that book. Very helpful. Thank you Debbie! Jon

I don’t have a lot of experience with these …

but the Bessettes’ SE mushroom book states that:

craniiformis often has a wrinkled or grooved spore case surface, as well as a yellow-brown, never purple, spore mass at maturity.

cyathiformis has a smooth case, that becomes aereolate at the top before the plates break off.

otherwise, grossly, they are quite similar.

How do you tell this apart from Calvatia craniiformis besides the purple gleba at maturity? See… http://mushroomobserver.org/177176?q=2BIE4

Does one have a specific pattern to the peridium?
