Re : is this a Hymenoscyphus on Nothofagus?
A negative reaction is no reason to doubt a Hymenoscyphus. But it would be helpful to study the ectal excipulum if prismatica or globulosa.
In her paper on Phaeohelotium nothofagi (2006) I also do not see a species with such wide spores.
It may be reminiscent of Phaeohelotium terrestre and allies. but these are mycorrhizal and the spores with a few large instead of many smaller LBs.

I will check the excipulum, thank you Hans-Otto!
