Re : Calycina claroflava?
The uploaded images are much too small to see or read something. Since you mounted in lethal media you cannot be sure with spore septation inside the asci, this needs to be checked in living asci. Negative IKI reaction and absence of croziers are essential, and living spores and their contents would be welcome.

Re : Calycina claroflava?
Thank you for the very helpful reply. The photos were reduced as I didn't think full size ones could be uploaded (which is why I quoted the spore and asci measurements in the text), but maybe I over-reduced them. I will try again with mounting in water. I had not appreciated from FOTE that they needed to be live spores. Is the iodine reaction with K as well as iodine? (I have had trouble with lichen identification where I using K as well as I when it was supposed to just be I, so I'm not too sure about how this one should be done. Many thanks again.

Re : Calycina claroflava?
In lichens as in non-lichens you may always use Lugol without KOH. If Lugol (IKI) is negative you can be sure that K+IKI is also negative.
Ascofrance reduces the images automatically when they are too large.
