quite the disparate range map, though, from Europe (and Japan!) to the Sierra!?! Perhaps it was one of those Italian or Japanese tourists, walking those forest paths with spores on their clothes?

Gotta love those international vectors, at least sometimes. ;)

Here is a great write-up of a T. squamosum collection, both macro and micro. It’s in Italian, but photos are a universal language: http://www.naturamediterraneo.com/...

Not sure how much variability there is in Tulostoma spores, but you are right in that the two micro-photos appear very similar.
