Patellaria atrata?
Fred Rhoades, 24-05-2016 02:34
Found near Cle Elum, Washington, USA
On decorticated Abies trunk lying on ground
"Apothecia" are quite gelatinous when fresh but very brittle when dried.  Difficult to get good sections.   Seems immature as there are no free spores but a few asci with multiseptate spores within.  Very thin, branched paraphyses.

I was wrong.  Asci do not blue in Melzers.  It was some of the subhymenial hyphae

I have added oil immersion views of asci and paraphyses mounted in Melzers

Re : Patellaria atrata?
If you have Lugol I wonder about the reaction of the asci. Also a closeup of the ascus tip under oil immersion would be helpful.
Perhaps a Claussenomyces which rarely have amyloid asci?
