Jacob: I agree with you about , “differences between the continents are typically between species, not genera”. However, if in fact “our “pyriforme” might not be their “pyriforme””, then changing the Genus name to Apioperdon while maintaining the same (possibly incorrect) epithet makes no sense. One should not make blanket assumptions about NA species without NA species being analyzed. This is not so much an issue of “lumping vs. splitting” as it is of wanting a complete study made before assigning taxonomic changes to NA species based on the study of European species. Thank you.
Differences between the continents are typically between species, not genera. While our “pyriforme” might not be their “pyriforme”, they’ll certainly be close within whichever genus they’re assigned.
This is an issue of lumping vs. splitting – if you accept certain other segregates of Lycoperdon as genera, you might need to accept Apioperdon as well, being a more basal clade.
We have decided not to accept this recent name change. From what we can glean from this paper by Vizzini and co., they analyzed a very limited sample of L. pyriforme (2) from who knows where (never clearly stated). We are assuming European specimens. Which begs the question of how this applies to NA species? In our humble opinion, this name change is not applicable to NA Lycoperdon pyriforme until NA species have been similarly included in their study.
