Tulostoma poculatum

T. poculatum has almost smooth spores and a membranous exoperidium. Picture keying has limits especially with gasteromycete complexes such as Lycoperdon molle – Lycoperdon umbrinum where there are lots of intermediate species that fix in between.

With Tulostoma the three basic characters are mouth type, exoperidial type, membranous or granular (hyphae-sand matrix) and spore ornamentation and size. It looks too robust for midwestern poculatum but pictures can only lead you so far. in this case Tulostoma sp. is as far as I can guess.

You’re right, no chance

But I was wondering if Tulostoma poculatum is a possibility?

Probably not Tulostoma brumale which has a tubular mouth and at least in european collections has a dark ring the mouth. In Europe T. brumale is associated with moss. Based on your photos the mouth looks lacerate-fimbriate so I’d put it in the T. fimbriatum group of Tulostoma species.
