my mushroom

[james brown]

my mushroom has large white bubbles in the middle, I don't think this is normal. the other day it excreted a long red string. does anyone know what is wrong with my mushroom?

Are your lights weak? If so, the red stuff may be photosynthetic algae, which probably means there is not enough light. If your lights are not weak, then the red stuff may be poop? Don't know about the bubbles, but if they get bigger, and they look like they can be pruned away, I would do it.

How large are the large bubbles? It is common for algae to grow on any bare spots of mushroom rock. As the algae goes through stages (i.e. chocolate brown) it will often produce air bubbles. These are usually no larger than a bb.
