Axolotl fungal disease?

[Luna]

Hey guys, when i first got my axolotl some of her tail was missing and there was a little white/grey lump on her tail (shown in the picture) she also had a little discoloration in the form of a circle. Recently it has become more white/grey in color and i was wondering if there was anything wrong with her, maybe like a fungal disease or if she has been hurt and trying to regenerate
Thank you

I haven't actually seen regeneration in the process, so I'm not sure if the white is normal. What is the texture of it? Fungus is generally fluffy I think, this looks a little slimy, like skin?
If you think it's fungus you could pop her into a salt bath for a couple of minutes, and try fridging. Fridging might also speed up the regen process, if that's whats happening.

Its more slimy than fluffy, it has been there since i got her its just that its more white in color now

How long have you had her? Perhaps just give fridging a go, until someone who might know anything about this pops us?
Also, what are the tank parameters: temp, ph, ammonia, nitrate, nitrite?
