This observation came from one of my neighbor’s front yards. Sporocarps are quite soft, mushy, and probably too mature for anything but trying to grow it. No collection made. Attempted to cut it open with my penknife, but peridium tore more than sliced. Gleba a mass of dark green spores as shown, but near base of peridium there are tiny warts present. Peridium composed of at least 2 distinct layers, the outer layer sluffing off quickly, the inner layer more persistent.

Thanks for all the photos of this species. A defining photo seems to be an old fruiting body that has hollowed out the spores, like the drawing in Smith, Smith & Weber (1981), called V. depressum in the 1973 edition. This species seems to be very close to the common Vascellum pratense. Smith (1975) has a color photo and Smith, Smith & Weber (1981) has a good drawing. The excellent work by Scott Bates has it keyed out, but no photos. As far as I can tell the main macroscopic differences are:
V. pratense: Opening at maturity medium sized, up to half of the top surface. Membrane separating the gleba from the subgleba distinct and easy to find.
V. lloydianum: Opening at maturity large size, up to the entire top of the puffball. Membrane separating the gleba from the subgleba indistinct and difficult to find.
