Enrique Rubio, 12-02-2010 12:06
Enrique RubioHi to all:

Re:Calycina on Rubus stems
Asci up to 58 x 8, IKI bb, 8-spored. I doubt about the existence of croziers. It seems to have only incomplete croziers from asci uncinate at their base.

Ectal excipulum. I dont'know this species: Calycina deuncinata?. I think is not Calycina (Phialina) separabilis.
Mant yhnaks again for your help

Hi EnriQue,
Why not a Hyaloscypha?
The hairs look very much like it.

Re:Calycina on Rubus stems
Hi Stip
Do you think the asci have croziers?

Re:Calycina on Rubus stems
Hi Enrique,
i would judge it as simple septa, there is the downward hook at he base as in Olla transiens.

Re:Calycina on Rubus stems
Yes. I think so. Perhaps you are right. Could be a Hyaloscypha species; Hyaloscypha herbarum. But the hairs are so many short!
Many thanks again
Enrique

Re:Calycina on Rubus stems
Hi Enrique,
i think H herbarum (type on Rubus frut.) fits very well, even the downward hook is drawn by huhtinen, only you measure the spores a little bit wider.
