Mushrooms Mutating?

[Miss Wiggle]

well i know there's all these different varients of mushrooms, colours, textures etc etc..... we only have one sort in our tank they're brown with greeny/blue stripes....... now we've got new ones coming up all over the place, but one of the new ones has all these bumps on it, they look pretty well ordered and regular so i don't think it's a disease or anything. would it be normal for one to just go different with just one species in the tank? i've no idea how they reproduce but i'd just kind of assumed the varients would be produced if you put two different types together. is it just a random genetic mutation??

would someone like to explain to me what's going on?!

Are the new different-looking ones smaller? When mushrooms spread the young offspring look nothing like the mother colony until they get larger. You've seen my green striped shrooms. When they're young, they are solid purple and bumpy. As they grow they develop into the green stripe coloration of the adults. Mushrooms will usually either split in two down the middle (not quite common) or grow a new head underneath the mother colony and then one or the other will float around the tank at night to a different spot (very common)

hmmm we've loads of other babies though and they all look the same as the adults.... the colouring on this one's exactly the same, just got bumps on too

we've thought we've seen them splitting, the one in question is coming up underneath and next to another bigger one.
