Next, the damn little white balls. What the hell is this crap? I saw it at the very bottom of one of my containers years ago when I dumped out a spent plant. I didnā??t think anything of it, except that it was kind of weird. But that plant was healthy, if memory serves.

Is this the mycelium that people speak of? It doesnā??t look stringy like is described in what I have read so far, so I think this is not it. On the other hand I guess I could be mistaking some for roots. So what are the balls? Has anyone seen anything like it before? Is it some kind of fungus? Since the bottom of the medium was too wet and moldy in spots, seems like it could be a fungus of some sort.

Just incase anybody is interested in reading more about mycelium, hereā??s the biggest organism in the world, right here in my home state:

And hereā??s an excellent article from the Australian government explaining nearly everything about mycelium, and how rhizome got his name (itā??s got pictures folks):
