Salut à tous,
I found these apothecia on weathered Malus bark 5ft from the ground 8/5/2015. They measure up to 0.8mm.
Ascospores 14.3 - 19 x 5.3 - 5.8, 3-septate
Asci bitunicate (?)
My specimen seems a reasonable fit for H.prostii, though the ascospores seem just a little different (particularly in guttulation) to the ones presented here:

This is a group I'm not really familiar with.....Can anyone please confirm?
Amitiés,

I measured, for example, *15-20 x 6-6.4 µm. Oil drops are generally a few small, rarely a larger one. Yes, asci are bitunicate.
Here an example.

Thanks Zotto!
Managed to correct my spelling error in the title of this thread, too :)
