Rutstroemia?
Yatsiuk Iryna, 18-10-2010 15:34
Yatsiuk IrynaHello, everybody!
This fungus was collected on plant debris in oakwood.
Some microscopic dimensions:
Sporesize - 13-17 * 3,8-5,3 um
Asci: 100-120*8-9 um
Small spores (presumably conidia?) are presented - 3,6*1 um
Apical pore blue in IKI
Pleace, help to determinate. I'm only beginner in studying discomycetes, so be grateful for any adviсe!
Thank you,
Irina

Re:Rutstroemia?
dear Irina

yeas that looks like Rutstroemia firma. Your spores looke septate but mature spores are still aseptate, and wehn alive contain big drops.

The conidia formed on the overmature spores are subglobose and contain one drop. Do you have the fungus still fresh? Did you try mounting in tap water?

Re:Rutstroemia?
Dear Zotto,

Thank you very much. This specimen was mounted in water. Unfortunately, I don't have fresh one.

Re:Rutstroemia?
Hello Irina and Zotto.

I just happened to study a specimen I suppose is R. firma. It's quite common here in late autumn on Betula twigs.

Here's a poor photo of spores in water.

Re:Rutstroemia?
Yes, that's tres bienn. And it is easily seen that also fresh material contains dead spores (the two on the right).
