Re : Octospora rubens?

Hi,


I would suggest that you have Octospora rustica-your spore dimensions fit nicely with that species. I have recently collected O. rubens from burnt ground and the spores were 16-19 x 11.5-13 and also the paraphyses tips were a bit more swollen. I've used Microfungi on Land Plants by Ellis and Ellis which may be slightly dated.


Regards,


Charles.

Re : Octospora rubens, Octospora rustica?
Hi dear Riet,
I agree with your determination.
Beside the colour of the apothecia, hence the species name, apos of O. rubens often (but not always) show a distinct margin whereas O. rustica does not. But, more important, on your nice pics of live material one can observe the vacuolar bodies in the paraphyses -a feature paraphyses of O. rustica do not have.
Here's some more info in case you were interested:

Re : Octospora rubens, Octospora rustica?
Hi Riet, Charles and Marcel, 
yes, the content of paraphyses as well as colour of apothecia fit well Octospora rubens. It's nicely illustrated by Billekens. But what about the structure of ectal excipulum? In this aspect Riet's find is definitely more similar to O. rustica, at least when comparing with the illustrations from the paper mentioned above. 
I also have a find from Olomouc combining paraphyses with VBs + ectal excipulum formed by textura globulosa-angularis. Zuzana

Hi, I can't contribute to the structure of the excipulum, but here two very old microfoto and a link to an interest website.

Greetings Peter.

Re : Octospora rubens, Octospora rustica?

Hi',


In the light of all this additional information I would concede that O. rubens is much more likely and that what I had found (apothecia more orange and paraphyses lacking vacuoles) fits much better with O. rustica.


Regards,


Charles.
