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

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.

Irina?

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...
