Looking for opinions on this Rutstroemia.
Collection date 16. Oct, on a twig, possibly of Alnus.
Spores measurement:
22.2 - 24.1 × 8.4 - 9.4 µm
Q = 2.4 - 2.8 ; N = 19
Me = 23.1 × 8.9 µm ; Qe = 2.6
The spores have reddish color.

Re : Rutstroemia sp. Nov '21
This requires a closeup of the ectal excipulum. Is there a gelatinous layer?
You should compare R. alnobetulae.
Which altitude does it come?

Re : Rutstroemia sp. Nov '21
I am afraid I don't have much better photo of the excipulum.
I did compare it with R. alnobetulae but it didn't fit, as per R. Dougoud paper:
spores are wider (Q=2,6 while in R. alnobetulae Q=4), no mentioning of this spores reddish coloration and paraphyses are inamyloid.
Altitude is 500 m.

Re : Rutstroemia sp. Nov '21
Yes, the strange blue IKI reaction of the VBs in the paraphyses! And your spores are much too wide.
But I now see that R. alni (17-24 x 7-9) would come close to your data.
I think Rutstroemia is rather host specific, so the substrate should be clarified by wood anatomy.
