A worldwide community photographing and learning about wildlife
What you're holding in your hand is just the leftover sterile stem base. The globe on top is where the spores were. The two days of heavy rain is when the spores got dispersed (maybe not very far!). The whole top disintegrates with these, just leaving the base.
The white stripe on the leaves makes "star of Bethlehem" more likely. Compare to Ornithogalum umbellatum.
If this is about 1-1/2" tall like it looks, I believe this is an old deflated Lycoperdon perlatum. Calvatia is much larger, and the stem base left is smooth across the top, not deflated like the one in your photos.
This is not Artomyces pyxidatus (crown-tipped coral). A. pyxidatus grows on wood, is white to pale tan and has very distinctive crown-shaped tips, even when very young.
Also called "Merulius incarnatus," and just to be clear it is found growing with FALSE turkey tail--Stereum ostrea.
