Superman Shroom Question

[FriendoFish]

Hi guys! I got a Superman mushroom frag about 7 months ago and after some moving around to find the proper placement he has been growing really well! The only thing is, it just keeps growing and growing without splitting. With all other mushrooms I’ve ever had they’ve split by this point. My parameters are stable and everything and I’m honestly not worried, but I’m just curious if anyone knows why this is happening. Thanks!

Idk man, I have a Superman and it’s just growing too. None of my mushrooms have split actually. One has spawned a new baby but none have split. I’ve got an orange and blue rhodactis the size of my open hand and it absolutely refuses to split. Anybody have any ideas?
