Thanks for highlighting that which I neglected to note, that of white oaks.
They "resist" Gerrit, but we must plough on!

1) to be variable in its capacity, largely depending on host species and 
host vitality. there are some species of tree, with particular attention 
drawn to Aesculus hippocastinum and variants within which G australes 
abilities to penetrate reaction zones is frightening and rapid. on oak it 
is a different animal all together
1) this is true for "white oaks" such as Quercus robur and Q. petrea, not 
for "red oaks" like Q. rubra (see 2).
2) one standing dead and one living (for a limited timeframe) with g 
australe (both Aesculus) One willow also dying with ganoderma australe (now 
in panic mode) so prediction that the tree will soon be dead some time next 
year (to be confirmed) I have already amassed a library of other cases that 
illustrate its potential.
2) Over the past 15 years, I have monitored and assessed the damage done by 
the mycelium of G. australe in over a hundred Quercus rubra, Aesculus, 
Acer, Salix, Populus and Tilia with (partially) sterile annual or perennial 
panic fruiting at the base of or up to one metre height on the trunks and 
almost always the drill of the resistograph went in at zero value
