Spores cylindriques-fusoïdes, lisses, à 2-4 petites guttules aux pôles, 5,5-7 x 2-2,5 µm, 6,3 x 2,03 µm en moyenne (15 spores), Q = 3,10
Asques à 8 spores bisériées, à contenu fortement dextrinoïde et à appareil apical fortement amyloïde en Lugol, avec un crochet à la base, 28-33 x 5-6 µm

Re:Calycina sp.
Obviously a Hyaloscypha. The hairs seem to be covered by yellowish resin? Such resin I only know from two conifericolous species, H. aureliella and H. britannica. The hairs are with 100 µm quite long, most species of Hyaloscypha have shorer hairs. And I see a rather large globose drop within the living asci which reminds me of Psilachnum, a genus I would exclude because its hair have another shape and are smooth

Re:Calycina sp.
Hello Zotto !
It's a great pleasure to read you.
In the key of Nordic Macromycetes Vol 1, I arrive on H. fuckekii var. fuckelii.
The hairs reach 90 µm. Our Hyaloscypha grow on Acer, not on coniferous tree.
All the caracters fit with that species.
I would like to have again your comments.

Re:Calycina sp.
yes, H. fuckelii var. fuckelii is with croziers, and apart from the resin I would agree. It will be best to use the Huhtinen key also. You can download it here.

I tank you for all.
