The apothecia have no ionomidotic reaction in KOH and the asci form very scanty primary ascosspores, difficult to see, but probably broadly ellipsoidal or subspherical, and finally the asci are filled with a multitude of small, subcylindrical to nearly allantoid, hyaline ascoconidia.
From the appearance of the primary spore it could perhaps be Tympanis tsugae Groves, which may now belong to Claussenomyces or Vexillomyces.
What do you think?

Re : On Pseudotsuga
Hi Enrique
not sure what Tympanis tsugae is but surely this is a Tympanis, not a Vexillomyces. The globose non-septate spores which form a short germ tube inside the living asci are diagnostic. Also the red-brown excipulum does not fit a Vexillomyces.
Ouellette & Pirozynsky used the germination pattern as species marker, but Tympanis is a difficult genus, probably not really settled.

Re : On Pseudotsuga
Thank you, Zotto
When studying this paper and although I do not see the germination of the primary spore at all well, I turned to this species. But, as you, I'm not sure.

Re : On Pseudotsuga
By the way, where is your folder on Tympanidaceae?
