I persist with this for the sake of the curious DIY viewers who are following the thread.
LHL,
Why do you constantly second guess me? Why would i advise a course of action unless i knew from experience that it was the correct thing to do? I am giving you free professional advice, that back in the day, people paid good money for.
How would it be possible to trace mycelium that is concealed under the plaster without removing the plaster?
In the pic with the joist tails exposed one can see the plaster that was behind the rotten skirting board, and this greyish looking plaster goes down between the joist tails. Please knock off all that plaster including the plaster from where the skirting board was previously fixed. Use a hammer and chisel, or use a large screw driver as a chisel. Please do the same to the plaster higher up the recess where mycelium shows.
Its irrelevant if the plaster is sound, you are looking for strands of mycelium behind the plaster.
