Eliminating the bark from the soil or the entire tree?  Repotting isn't an option now - any fungicide I could use?

If it doesn't seem to be affecting your trees, let it be.  

And just a thought:  Fungus seldom do well when water is scarce.  Could it be that your trees are wated too often -- especially at this time of year? ???

Experience tells me that the fungus can spread very quickly... Will keep the trees as dry as possible - let's see what happens. What strikes me that no one here has a clue what this is!

MatsuBonsai:
How often do you clean the top of your soil?  If you rake the top with angled tweezers you can remove a lot of gunk, pests, weeds, etc.

Soil seems kind of thick. Too soily.

No pine, no grit, more pumice.?

Hi Sorce,
i was under the impression that pine bark encourage myccorizia - that is why I mixed it in.  The only mediums available her in SA is grit, bark and soil. The pumice I had was a once off purchase.
There is no more thn 30% soil in the mix. Perhaps the pumice and seramis hold too mush water? The mix is otherwise free draining.
A local bonsai person told me to put an extra layer of soil on top during summer to avoid high temperatures in the pot...

Hello John,
Thank you for your reply.
The surface is free of any weed, bugs etc. All trees had been repotted 4 months ago. I did put an extra layer of grit on top to avoid the temperature becoming too hot in the pot.  We are already we'll in the 30's and summer are easily in the 40's here.
