Don't want to blame CA, but it does look like snow mold. I hope you got it
all washed off, that stuff is stubborn!

Also, the potting mix it was on didn't look all THAT old. So the stuff may
be growing in one of your bags of mix. Watch carefully next time you make a
batch. Kenni

I thought this was a bad case of mealies but upon unpotting, the
odor was a very strong mushroom mouldy type smell.

I call this stuff Flak but someone told me it is California snow mould?

I washed the plant removing all the bark mix from the roots, sprayed with
a
solution of water &
Physan, trimmed the dead roots repotted.

Just thought you may like to see some of the nasty stuff.
Cheers Wendy
