Scutellinia hyperborea?
Karl Soler Kinnerbäck, 12-03-2025 17:54
Hi all!
Do you agree with Scutellinia hyperborea?
Padjelanta national park, Sweden, alpine heath next to stream, 1000 m elevation, 2024-08.

Hairs 300-400 x 15-20, some bifurcated
Spores 17-18 x 16-18, fairly regularly ornamented with low warts
Measurements from dried material. Spores are smaller than in Schumachers description, otherwise I think it is a good fit.

Best regards
Karl

Re : Scutellinia hyperborea?
I would also compare with S minor

Re : Scutellinia hyperborea?
I also have a collection (from the Alps) which I am not sure if it is hyperborea or minor. What are the most important diagnostic differences?

Re : Scutellinia hyperborea?
I think the major difference is that in S hyperborea the warts are generally smaller and have a much more uniform size. S minor has more unevenly sized warts spread over the spore surface. The few clear photos of the spores of this find look to fit better with this latter criteria.

Re : Scutellinia hyperborea?
thank you, Malcolm! This will help me when I take a closer look at my collection. Your contribution motivates me to do this quite soon :-)

Re : Scutellinia hyperborea?
Hi Malcolm and Lothar!
Yes, as I also understood it the warts are somewhat higher and more heterogenous in minor. When I compared with literature I was almost certain it was hyperborea, but if you are leaning towards minor I will study the collection again. I will soon have better equipment and try some photo stacking. Thanks Malcolm

Best regards
Karl

Re : Scutellinia hyperborea?
I do not recognize S. minor on these pictures.
As a reminder, there is a key to European Scutellinia available here: https://doi.org/10.25664/KEY-0008

Re : Scutellinia hyperborea?
Would your suggestion be hyperborea then Nicolas?
