Protounguicularia transiens?

Hi! One more found on old Populus tremula log in Oslo, Norway. Apos 0.1-0.4 mm. Spores ca. 6-7x3-3.5 micr. with two large guttules. Hairs with glassy, amyloid tips. Some hairs with orange incrustration/resin. Asci IKI+ (blue in Lugol). Not sure about croziers.
I think it looks a lot like Protounguicularia (Olla) transiens, but both asci and spores seem to be a bit too broad. And does that species have coloured incrustations?
Some apos associated with a white anamorph (photo), but probably just a coincidence.
Are there other possibilities?
Thanks!

Hairs - glassy ones in Meltzer's, incrusted ones in water.

Looks much like Olla transiens. Yes, the spores are a bit broad, but such occur.
Living asci are (6.5-)7.5-8.5(-10) broad.
The species occurs in a brown variant with heavy brown incrustation. JP Priou observed spores like you, with partly large drops:Â JPP 26058

Re : Protounguicularia transiens?
Thanks again, Zotto. Apos turn a bit brownish with "age".
