As documented elsewhere in my busy online existence, last week Kate and I saw an unfamiliar fungus-like growth next to our driveway (the one in the foreground; the red thing in the background is our '93 Honda Civic). We called over our neighbor Jill, a mycological hobbyist, to see what she thought it might be. She agreed it might be a mushroom, but had no idea what kind. I think she talked to a more expert friend, who talked to a more expert friend, and they came up with an identification: Clathrus ruber. Or latticed stinkhorn, if you want to be less Latin about it. Sort of exciting to find some documentation about it:
"A spectacular and beautiful fungus, Clathrus ruber makes a remarkable transformation from a white, bumpy-surfaced, egg-stage, to a bright reddish-orange, hollow, fragile lattice-work structure. Unfortunately, the beauty of this fungus is overshadowed by its odor, which is of rotting flesh."
