Myrmecophilia with Ice on the heat?!

[jrguevar]

Greetings everybody,

In new to the website and trying to get used to the forums and everything. I would like to have any feedback on what just happend to the oldest bulb of a section I removed a couple of days back which apeared as if snow had fallen on the leafs, curiously only the oldest bulb appeared like this. Any suggestions on what could be happening?...

Welcome!

It looks as though a fungus is spreading through the leaf. It might also be small insects tunneling through the leaf.

Cut them off as soon as possible and it shouldn't spread. Doesn't look to worrying

As soon as I took the picture I cutted the affected leafs and sealed the wound. I wanted to have some tecnical feedback maybe what type of fungus or bacteria according to the symptoms shown and described in the original post.
regards

Are you near a university or college? Somebody there may know what it is.
