Firstly I made the identification of the species without recourse to microscopy: Fuscidea lightfootii. I was fairly confident about it, based in the descriptions and the photos that I saw. Then passed to microscopy and aparently something didn’t match because the spores seemed to be septate whereas in the description they where described as simples. A further look to the descriptions convinced me that everything worked: indeed, the spores present two vacuoles and are constricted in the midle, so appearing septate (mainly when observed with a bad equipment like mine). The spores are hialine, very small (I could measured a few with ~ 9 × 4 µm) and live in groups of 8 on asci of Fuscidea type, exhibiting an intense IKI+ blue reaction on the tholus (apical dome).

on myspecies gallery, as well. It’s especially tough when they’re so small.
The spores seem septate to me. Only now I realize that the photo with the microscopy is missing. I will upload it now.
Those totally look septate to me, as well. I would’ve been fooled, too. Nicely done.
