Recently I posted here my finding of small white apos growing on a fallen Picea abies cone. I found these once again, but this time on a fallen Pinus sylvestris cone.
This species seems rather distinctive, and apparently at least locally common as well. So I decided to post this finding as well — this time with better data. Could this be identified even to family level?
The apos are sessile-substipitate and 0.2 - 0.4 mm wide. Asci 8-spored, IKI+(b), croziers present. Paraphyses narrowly cylindrical, with multiguttulate tips; similar cells on the margin. Extal excipulum with angular-globose cells and round guttules.
Spores with two large guttules and some smaller ones. Some spores appeared to have a gelatinous sheath. Measurements:
(15.1) 15.8 - 19.3 (20.4) × (3.4) 3.7 - 4.2 (4.4) µm
Q = (4) 4.3 - 4.8 (5.1) ; N = 10
Me = 17.9 × 4 µm ; Qe = 4.5
Q = (4) 4.3 - 4.8 (5.1) ; N = 10
Me = 17.9 × 4 µm ; Qe = 4.5
Asci:
69.1 - 90 × 9.8 - 12.4 µm
Q = 7 - 7.4 ; N = 3
Me = 79 × 10.9 µm ; Qe = 7.2
Q = 7 - 7.4 ; N = 3
Me = 79 × 10.9 µm ; Qe = 7.2

Re : Helotiales on cone again
This doesn't look the same as that on Picea if you mean that.
The apical ring is rather thick and the apex very conical, also the VBs in the paraphyses are restricted to the apex. H. epiphyllus would be multiguttulate in the cortical excipulum.
I am unsure for a genus, rather Calycina than Hymenoscyphus?

Re : Helotiales on cone again
I mean this one from a little earlier:
The Hymenoscyphus was on a Pinus cone as well (on the core part).

Re : Helotiales on cone again
Ah o.k., now I remember. The paraphyses look like in Hymenosc. sparsus but that is a stipitate fungus on leaves, with typical Hym.-type of apical ring.
