Tiny discos on Populus

The spores measure 9.4 - 13.1 × 3.9 - 4.2.
Any idea what might be the species/genus?

Re : Tiny discos on Populus
This would require a section. Is the excipulum porrecta? gelatinized?
Perhaps a Hyaloscypha (minuta, intacta...)?

Re : Tiny discos on Populus
Thank you for the reply.
Unfortunately these are so small that I won't be able to make a section. But I studied the sample a bit more.
Some spores have a septum and there is a rection with the excipulum and the margin with Melzers'. I measured three asci and they were 57 - 65 × 9 - 10.5 (H2O).Â
H. minuta isn't found on our species list or in the monograph, but H. intacta is. It seems to fit in other parts, but there weren't even short hairs to be found. Is there a hairless version of this?

Re : Tiny discos on Populus
H. minuta is newly combined and you find it in my Hyaloscypha folder. Yes, it is a hairless member or may have very very short hairs. It is not easy to be separated from H. intacta. Sequences exist, and as a preliminary result the two species are the same. Of course, the types are relevant in this concern. That of H. minuta I have redescribed in detail, and that of intacta Seppo has.
Strange is that the two species were described in the same year.
B.t.w., dextrinoid reactions of the ectal excipulum have variously been recorded by Huhtinen.
