AZALEA LEAF GALL (EXOBASIDIUM VACCINII) ON AZALEA 'TIT WILLOW'

Well, this is a new one!  A first for me.  After many decades of gardening I have discovered yet something else I have never seen before.  Gardening is full of surprises.  Exobasidium vaccinnii, a fungus also known as Azalea leaf (or flower) gall has got a hold on poor Azalea 'Tit Willow', the little azalea which I uprooted to make way for my new garden room in spring.  Seems Tit Willow is not happy.  After photographing the strange, white, puffy growths on the branch ends, I did a bit of research on the net and came up with the name of the problem.  Actually, they look rather like prawn crackers.

Seems the remedy is to snip them off as soon as you see the problem, dispose of the cuttings where they cannot contaminate further, and clean your secateurs.  I cut the little branches well back, and only found the problem in four places.

Below it looks as if the fungus has attached itself to a spider's thread.
