Ciboria coryli?
Yatsiuk Iryna, 20-07-2011 14:43

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

Re : Ciboria coryli?
Seems you have strongly squashed your spores, so they got wider than normal. Yes, with this spore size it must be C. coryli

Re : Ciboria coryli?
Hi all,

  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).

Hi 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.

Thank you,
Zotto, now I see that I really squashed spores my preparation.

Hi Irina,

I was lucky to see the nuclei in my collection...

Best wishes,

Re : Ciboria coryli?

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).

Hi there!
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.

Re : Ciboria coryli?
Yes Irina,

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...
