Durella macrospora?

I collected this yesterday in dry state and it is mostly dead. Substrate is Fagus sylvatica. Apothecia are up to about 0.5mm in diameter and full of lipid contents, so much that it accumulates on the surface of some apothecia. Ascus apex is red and sometimes blue in IKI and blue when pretreated with KOH. I had a hard time finding spores and most of them are at least partially dead. Their size is roughly 15.2 - 18.1 x 3.3 - 4.2
Can i nonetheless file this as Durella macrospora?
kind regards
PhilEsc

Re : Durella macrospora?
Yes, and it is the amyloid form with the abundant hyaline exudate droplets around the paraphyses which I recently missed in the inamyloid form from Ethan Crenson.

Re : Durella macrospora?
About the hyaline, strong refractive interhymenial droplets. This seems not to be Oil (sensu Oil droplets inside the spores), because they are CRB+, but they are not VBs, because they are still present in dead apos, as far I remember.
And something interesting I saw: the droplets are loosing they refractivity in KOH, but still a non refractive shield is visible.

Re : Durella macrospora?
Of course they are not VBs which occur only inside cells. :-)
Yes, but I see that Stip once noted CRB- for them (HB 6645) and I noted KOH-inert (HB 4393).
