Laetinaevia-like?

This was found growing quite abundantly on a decorticated area on a thin (6mm diameter) Fraxinus twig. Pale peach-coloured when fresh, and small (max. 170µm diameter).Excipulum composed of rather thick-walled cells.
Asci 8-spored; in IKI apparently no reaction - possibly very faint hemiamyloid, though this might be an artefact; strongly blue in KOH > MLZ). Difficult to see but probably croziers +. Paraphyses not swollen at apex, without guttules.
Ascospores ellipsoid to (mostly) broadly reniform / bean-shaped; guttules as in the images.
Any thoughts would be welcome.
Chris

Re : Laetinaevia-like?
Hi Chris
with such a strong amyloid reaction the unpretreated asci should distinctly react red! Maybe your Lugol lacks iodine?
No idea what it is. A closeup of the apical ring could be valuable

Re : Laetinaevia-like?
Thanks Zotto
yes I'll have another go tomorrow, mounting in pure IKI, rather than running it into a water mount as I did in this instance (although that has usually worked well for me with many other species).

Re : Laetinaevia-like?
It is the better method to add IKI to water (not too much water) because only then you can view the change from blue to red in some taxa. But it must be concentrated enough.
