?Calycellina on Picea cone

Yesterday I found some small white Helotiales growing on scales of a fallen Picea abies cone. At first I presumed they were Hamatocanthoscypha laricionis, but since under the hand lens they didn't appear to have hairs, I took the cone home.
The asci have eight spores, croziers present, IKI+(b). The paraphyses are narrowly cylindrical, and the top parts have a cluster of small VBs. Similar cells present at the margin. The spores have two large guttules and a few smaller ones.
Spore measurements:
(12.9) 14.2 - 17.8 (20.2) × (3.6) 3.61 - 4.5 (4.6) µm
Q = (3.4) 3.5 - 4.4 (4.5) ; N = 10
Me = 15.9 × 4 µm ; Qe = 4
Q = (3.4) 3.5 - 4.4 (4.5) ; N = 10
Me = 15.9 × 4 µm ; Qe = 4
It seems this could be a Calycellina species or something close to that.

Re : ?Calycellina on Picea cone
The multiguttulate paraphyses are impossible for Calycellina. The apical ring excludes a Hymenoscyphus. Hard to tell.
The apo is between 0.5 and 1 mm? No stipe at all?

Re : ?Calycellina on Picea cone
I see, that's interesting. There wasn't any proper stipe at least -- at best a wide and very short one (nothing like in typical Hymenoscyphus or Antinoa). I have photos of two apos, and the width measured from them is 0.3 - 0.4 mm.
