Hello I want to ask you if you have found this ye
Hello,
today I found a small white Hyaloscyphaceae on bark of a lying twig of Fagus, in the direct vicinity of Diatrype decorticata.
Annoyingly I found this species already last year here in the Bavarian Forest several times, and this year they occur again on the very same twigs as last year.
As I don't arrive at a determination, I would be very grateful for a help on this.
Apothecia pure white, not discolouring, pruinose to slightly tomentose, margin lobate with age.
Asci appr. 65/5 µm, with croziers, reddish-blueish in Barals (dirty violett).
Spores 7-8 x 2,2-2,5 µm biguttulate
Paraphyses cylindrical, with refringent content .
Hairs at the margin difficult to detect, very similar to the paraphyses, with refringent content in upper half
Excipulum built of textura oblita (!)
thank you for any hints.
best regards,
Andreas
