Calycina on Betula wood

... also from the National Park of Eifel, Germany.


I am quite sure about the genus, but find no fitting species.


The apical apparatus reacts blue in IKI (Calycina type), croziers are present. Overripe spores are 1-septate and germinate to buds.


Best regards from Lothar

Re : Calycina on Betula wood
The spores remind of Leptodontidium trabinellum (earlier Phaeohelotium or Calycellina). But the apos are a bit too white. You could look whether the paraphyses are densely septate at the base.

Re : Calycina on Betula wood

... o.k. - in my mind trabinella also is something more yellowish or even nearly orange. But maybe in very young stage it is whtish???


Thanks for your opinion an best regards from Lothar

Re : Calycina on Betula wood

... ah - the paraphyses-septation. I could do this, but it has to wait. The specimen is dry now and a lot of other work to do.


Thanks for the tip! Lothar
