though with all the presumably valid spp. of Reticularia (according to MB and IF), not to mention the closely allied Enteridium with which various Reticularia are synonymized, this could be another catch-all taxon for things that more or less look alike. That taxon alone has two separate varieties, R. var. americana and R. var. lycoperdon.

Seems like a rather daunting line of investigation without a resident myxogastriologist (?) on hand. Even the two Japanese slime mold books I just added to my shelf don’t deal with more than two members of each of those genera, and only cursorily at that.

great job, Myxo!

And it seems we are not the first to see it and think “puffball.”

Common name: the “False Puffball!”

Stream-side location on downed wood fits as well.

Thank you.
