I just moved to Edmonton and I saw one of those today at the park! I thought it was a ball. I’ve never seen them before.
Heh. I went to a tomato festival in West Sussex today - we arrived a bit early and were more or less the first to be directed into the parking area, which was field/pasture - as we drove across, I yelled to the missus “Don’t drive over the mushrooms!”. when we parked, I jumped out and ran back to look.
I picked about a pound of field mushrooms, a massive horse mushroom (the cap is 9 inches in diameter) and a giant puffball - not a huge specimen, as they go - this one is about the size of a baby’s head. I’ll post pics when I cook and eat it.
I know, but it’s not a) above ground and b) two blocks from my house. Therefore.
I wonder what the fungi produce the world’s largest fruiting bodies, though.
We used to eat them occasionally when camping in a friend’s woods, because they were extremely common there. Not much to report. Not much flavor. We stuck to the scotch, stew and smores.
Maybe they are trying for the US Open?
The giant puffball might be a contender, depending on how the question is formulated - certainly the fungus has to be one of the largest non-persistent fruiting bodies - I’ve heard (anecdotally) of cases where an exceptionally large specimen was mistaken for a sheep.
But some other fungi produce fruiting structures that go on for years and years - and because of this, they can be enormous - on my recent holiday to the Highlands of Scotland, I came across this massive shelf fungus on a huge, ancient beech tree.
When we were there, it was lightly raining - the lower of the two fruiting bodies shown in this picture is large enough for two people to take shelter underneath.
However, only the lower, white layer of these fruiting bodies is actually alive - the top, brown part is like cork or wood.
We ate the giant puffball for lunch today - it was quite nice. Details and photos here:
Cool, thanks for the pictures!
I’m too lazy to check if you posted to this thread about breakfasts. 
If we ever have fungal overlords, they won’t be puffballs, they’ll be Cordyceps. Apparently some of those are consumed as a traditional Chinese medicine, so there are plenty of opportunities for it to mutate into a form that infects humans. (Or at least that’s how it works in my plot for a Scyfy Originial Movie.)
Oh YEAH!
