Rot BojanHello, by appearance I would say that I am dealing
Hello, Forum!
It was collected in 22 March? 2011, on catkins of Corylus avellana.
Looks like Ciboria coryli, but I'm not sure. Is someone familiar with this species?
With best regards,
Irina
Zotto
here some macro and microphotoes of my collections:
1) The ascospores are binucleated (hard visible) and sometimes the external layer is separable.
2) The flowers of the catkins are dead unripe (in all my collections).
Erio
I fully concur, and I add that it is necessary to have living spores in order to see the two nuclei. I am not sure whether one can find living spores in Ciboria when the material was dry for some months.
Zotto
Zotto, now I see that I really squashed spores my preparation.
Irina?
I was lucky to see the nuclei in my collection...
Best wishes,
Martin
Wow! Was it a fresh specimen?
And I will wait for the next spring and do my best to look at fresh material (hope to have a field microscope by that time).
Irina
At least Ciboria conformata kept some spores alive after it was dry for a week. See attach, you can see some spores still with the nucleolus. I use little plastic bags to keep moisture in the field and then I put them as soon as possible in the fridge till I can study them.
Raúl
it is from a single fresh specimen, that I found in March this year.
Regards
Martin
PS: and as Raúl said: you don't need a field microscope. Just put your collection in a plastic bag or box and keep it slightly moist for comfortable examination at home...
