Every now and then after a big rain these crop up in my basement. No obvious cracks or anything where they pop out of the unfinished concrete floor. I try to dispose of them without too much opportunity to shake of spores, and then douse the floor with bleach, but I also admire their ability to grow with no apparent nutrients.
Worth noting that the mushroom itself is just a temporary reproductive organ that’s produced by the actual “body” of the fungus, which is a mycelial network spread through the soil. In this case the soil that’s under that concrete. There must be a fair bit of organic matter in that soil, that’s what the mushroom is feeding on.
Bleaching and cleaning the floor is fine, but it’s probably not going to seep into the soil under there so next time the fungus down below has gathered up enough nutrients to be feeling randy again it’ll just poke a new mushroom up through a crack. The cracks are probably just too fine to see. Maybe one solution might be to give the floor a really good scrubbing and cleaning, then once it dries spread some sealant on it? It’ll hopefully seep into the cracks and make it harder for future intrusions.
So is there a body buried under there?
The most reasonable assumption, yeah.
OP, have you mapped the spots where the mushrooms sprout? Is it humanoid-shaped?
No, pretty sure they buried the pieces separately.
A mycelium body yes 🙃
I can feel the moisture in that floor. You should get a sump fam.
Yeah, the basement has a dehumidifier, and almost all of the floor is very dry, it’s just this corner. Also there’s a ridge in the concrete and a clear border of damp versus dry. Usually it’s not nearly like this though, we just got about 4 inches of rain.
That’s a bolete, they grow in obligate symbiosis with the roots of living trees. Their mycelium can extend further than the trees root system so they bring nutrients to the tree and eat the sugars the roots produce.
This means they’re probably not gonna go away unless something happens to tree, and even then they’ll stick around for a while after it’s gone.
Interesting, the nearest tree was the street tree across the sidewalk at that end of the house, died a few years back and was taken out. Come to think of it, I’m pretty sure there were some roots coming through the stone foundation wall when we moved in (since sealed & insulated). There’s a new thriving tree in its place though, I wonder if the mycelium hop to the new roots.
If it’s the same kind of tree then definitely. A new tree can graft to the old root system and revive it which keeps the mushrooms alive even though the tree would normally be too immature to support that specific fungal partner.
I’m curious if you know what kind of tree it is, the bolete looks a bit like Suillus which tend to be really specific about their partner. If you’re in the Pacific Northwest region I could probably figure out the species from the tree.
Old tree looks like it was a maple?
New tree is a crab apple. I’m in New England.
Oh yeah no clue in that case, NE has more genera of boletes than the PNW has species.
Oh no. You may want to take a look behind that seal/insulation homie.
If you start feeling like bitting people, please consult a doctor.
But do not, and I cannot stress this enough, bite the doctor.
May want a dehumidifier in there if you don’t already
Eatit
I had a really cheap rental house one time with plywood around the toilets from which mushrooms sprung up. DIdn’t try them
When life gives you mushroom, make a mushroom farm !
I was watching all the cool things ecovative is making from mycelium and I admit I’m rather tempted. I have plenty of sawdust I could feed them.
The folks over at Mycology could probably identify it for you
mander.xyz is still down but I’m sure a lot of the folks there are also subscribed to this com.
Gross. Clean more.
