Re : Xylaria guepinii\ friesii?
Hello,
I was hoping that Thomas would answer because he revised the type specimen of X. guepini and created X. friesii.
In the meantime, based on your data and Laessoe's 1993 paper, I think your collection fits well X. guepini in all respects.
It is a poorly known species, rarely collected at sexual state, thus you collection is of great interest.
Thanks for sharing it.
Cheers,
Jacques

Re : Xylaria guepinii\ friesii?
Just back from Cuba (birding) to a closed university etc. I would agree with Jacques that X. guepinii is the best match (super material), but I have not studied this complex for decennia so feel a bit rusty. It is still a possibility that both scotica and my own friesii should be lumped with guepinii.

Re : Xylaria guepinii\ friesii?
Hallo all,
I read a new article about this species: Hsieh H-M, Ju Y-M, Lechat C, Fournier J, Huart D. New ecological, morphological, cultural and molecular phylogenetic insights into Xylaria guepini (Xylariaceae) Ascomycete.org. 2022;14:177–184.
I very much regret that the authors lacked scientific inquisitiveness and did not ask me for part of my collection for comparative analysis. :-( Especially since, when comparing the morphology of both collections, due to significant differences, especially (though not only) in the aspect of conidiogeny, it should be assumed that they are different species of the Xylaria genus.
I am fully willing to cooperate in further research on this species (unfortunately I do not have the ability to conduct genetic research myself),
best regards, Przemek
