>>1896531It was definitely Calvaitia cyathiformis. Here's the puffball maybe a week after I took the first photo, turned into a sort of weakly-held-together mass of spores. Took it around and tapped spores all over the place, so hopefully there will be more in the future.
>>1896857Yours will likely turn into something like this as well. Just pick it once it's turned a purple-ish grey and spread the spores around.
