Came home to my large mushroom looking like this

 

 

Never seen am mushroom split in person so I figured I would ask the pros

I had a mushroom just like this that died a long time ago. When it died it got super small. This seems very healthy other than the obvious. Curious to see what a more experienced mushroom keeper might think.

I've killed more mushrooms than I care to think about. Something is irritating it. It can definitely recover.

It's definitely his insides but he's still doing fairly well other than that. Hasn't shrank or last color

I didn't know mine split except for the little buds growing

Mesenterial filaments, as already stated, its guts they usually expel them when they're stressed. Just wait it out for a day or two and it should go back to normal. If your tank's really small, maybe run a bit of carbon during that time as well.

 

Shrooms also naturally grow new babies via pedal laceration or by growing new mouths and dividing like a cell. I don't believe expelling mesenterial filaments is a precursor to either but I do hope you get some babies from that thing ..so I can get one from you..
