Mirek GrycHi.These grew on pine wood that was heavily covere
Hello everybody,Last week I found this discomycete growing on dead stem of Rubus fruticosus, but I can't
determinate. What's your advice?
Details:
Apothecia 0,3 – 0,5 mm. across. Sessile. Turbinate. With white discs that
become pink-red (with age?). Â I have seen
no hairs outside (what's necessary in order to belongs to the Hyaloscyphaceae –
I mean?).
Asci:  IKI+. 70 – 80 x 6 – 7 mµ (with croziers- but I'm not certain).
Ectal excipulum of textura globulosa-angularis
Spores: 8 – 13 x 3 µm. curved,  1 septe
Parafyses without refractive guttules

Ps : dimensions ( x 1000)  1  = 1,01 µm
this is a Calycina, and one of those that turn red with age. Typical of the genus are the  apical ring type (very different from Phaeohelotium which has Hymenoscyphus-type), and the mollosioid VBs in the paraphyses (not clearly seen on your photos).Â
I also think yours has croziers. I would compare this with my C. heterospora nom. prov. which had partly spores of different size within an ascus, but not always. This ispecies s related to C. parilis and C. herbarum but certainly not the same.
