Re : Strossmayeria sp. on indet. decroticate hardwood
I see with dead material it is much less easy to observe free mature spores, because they are shot away during drying.

The ITS sequence fully coincides with one of Strossmayeria basitricha (ON254102 in GenBank, as Strossm. sp.) and almost so with one of S. basitricha of mine in GenBank.
