Hamatocanthoscypha conincola?

Hello, a large group of these purely white ascomycetes grew on Picea cone.Ascospores (4.6) 4.9-6.3 (7) × (1.4) 1.6-2 (2.3) µm, Q = (2.4) 2.7-3.5 (4), Me = 5.5 × 1.8 µm ; Qe = 3.1, 1-celled, smooth, hyaline, without guttules.
Asci inoperculate, (25) 27-30.6 (32.2) x (4.5) 4.5-5.8 (6) µm, with croziers, ascoapical apparatus blue in IKI (without pretreatment), 8-spored, spores in 2 rows, pars sporifera 10-13.7 µm. In some asci I have observed a guttule similar to those typical for Psilachnum.
Hairs straight or uncinate (but not so much as I know in Ham. laricionis), septate, smooth, some of them incrustated with hyaline matter.
I think it is Hamatocanthoscypha conincola, but ascospores and asci are somewhat smaller than what I found in the internet resources.
Thank you, Zuzana

Yes, I think it is. Similar spore size you can find in my folder, e.g. Ingo's 130903-01xsJ or HB 7928 (*4.3-6.3(-8.5) x 1.8-2.3 µm)
