Should I be worried? I was away for 3 days and this thing grew in the soil of my Monstera. Google told me it's a Shaggy Inc Cap Mushroom, but I'm unsure. How would that get in there? I repotted the Monstera back in March with fresh soil from the hardware store.
It's an ink cap (coprinus or leucocoprinus) for sure. Mushroom growth, especially this kind, is a sign of a fertile and healthy soil. Don't worry and let it be.
It could have come from the soil you bought, have been there before, got somehow carried by the wind. There's no way to tell...
Hi, thanks everyone for the helpful and kind words 🙈 I have to admit I did freak out a bit yesterday, since the Monstera is standing right beside my bed. I will make sure not to over water them,it is currently really hot here so I felt comfortable to give a bit more water in an attempt to keep the plants safe.
No need to worry, it's a fairly common mushie. That said, if your potting mix is that wet you may be overwatering or not giving a long enough period in between waterings
These things grow all over the place, including right in the lawn, when the conditions are right - shade and moisture mostly. Make sure you're not over-watering your plant and that it's in the sun the right amount and you'll be fine.
