Flasks will develop fungus sometimes.
Yes you can leave them in the flask for a while but it will consume
the whole flask in the end. I have let the fungus grow until the whole
top of the agar was white because I was trying to let the plants get a
bit bigger before deflasking.(and they are still alive and doing fine)
If the seedling will make it I would take them out now and rinse off
all the agar and wash the plants in Physon, then pot them up.
This way they will be adapted to the new enviroment before you go out
of town.

I have a flask of Phal. gibbosa that I just noticed a tiny white fuzzy
patch in. This is the first flask I have ever bought where I wasnt able
to open it up right away. I never opened it or disturbed it so I don't
know how it got contaminated.
The seedlings are not quite ready to come out yet, the leaves are only
about 1/2" long. I am pretty confident that I could take them out and
get them to live though. What should I do?
