hello everyone
We live since 3 years on a piece of land in the South of Hungary. the property was abandoned for many years and was full of wild grown trees. Mostly Robinia pseudoacacia, White poplar (Populus alba) and Common Hackberry (Celtis occidentalis). As we are cleaning out the land we discovered a black mold on many of the trunks of the trees. It is a sooty like mold starting at ground level. higher parts of the trees seem to be fine. It’s mostly affecting Robinia but 1 hackberry is affected as well. 5 km away from the property we discovered a planted pine forest where many of the trees seem to have the same problem. It appears on old robinia fencing poles as well.
On the living trees, the mold seems to grow on the outside of the bark, not under it. The trees which are worst affected are loosing their bark. Under some of the trees the ground gets black as well.
Does anybody know what this is and what to do about it?
Sorry for the bad English and thanks in advance!
