Bad if mushrooms are growing in my terrarium?
I just noticed I have mushrooms growing in my terrarium! Their growth seems only very recent, which is kinda odd considering it's over 6 months old and I've never opened it. Maybe I need to air it out a bit.
I think they look kinda cool so I'd be happy just picking out the dead ones, but I wondered if this is harmful to my plants. What concerns me isn't really the mushrooms themselves, but in the picture you'll notice a fine white sort of dusting on the soil and even on the leaves directly above the mushroom area. It isn't fuzzy or anything, and it doesn't seem to be killing the plants (yet?). Not sure if that's from the mushrooms, or a coincidental other mold/fungus, or simply a result of condensation? (I neglected to rotate it much and that's the side where most moisture has been collecting.) Advice appreciated!
