Joaquin MartinHi,I found this fungus in a mixed forest of spruce
is this a Hymenoscyphus on Nothofagus?

This is a quite common species on Nothofagus wood in southern Chile but I have not been able to identify it so far. Of course my first thought was Hymenoscyphus but what confuses me is that asci show no iodine reaction and the spores are wider than in all Hymenoscyphus species described by Gamundi & Romero (1998). Any suggestion?

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!
