Anyone have any idea what this is? It's only on one leaf and hasn't spread at all, nor has it grown or changed at all since discovery a week or two ago.

We had a bit of a gnat infestation a while back, but have been managing well - this plant is in water, in a glass bowl, and was unaffected but did suffer some algae growth a while back which I was able to clear out and have been keeping a close eye on.
