This appears to lack croziers.

My guess is a Psilachnum, such as P. miniatum. The last photo is a paraphysis or a hair?

Re : Yellowish asco on Pteridium aquilinum
o.k., now as you say it is a hair I would make a bet that this is a Psilachnum, and maybe P miniatum. I assume there is no official sequences.

sorry, Robin, and thank you. 
I only read the text of the contributions, not the title ...
Seems I am getting old ...
