Orbilia spec. 2
Gernot Friebes, 29-11-2009 12:59
here is the second one, which looks very interesting to me.

It grew together with the first Orbilia on a branch of Rosa ca. 150 cm above the ground. The spores are 11-14 x 2.5-3.5 µm, often septate (also in living state and inside the living asci!) with one (rarely two) septa. The SB is 3-4.5 µm long, slightly curved to sigmoid. The Asci are 8-spored and up to 53 x 7.5 µm.

Best wishes,

Gernot

forme des sspores +et Spore body + septation conforme pour setispora. la seule Orbilia septée Rosa semble être un nouveau support pour ce taxon..
Attendons la confirmation du Docteur es Orbilia.

Re:Orbilia spec. 2
Hi Gernot

seems actually to be O. septispora as Jean-Paul suggests! On your ascus photos it is not clear because they are so small, but if you say they were septate inside the living asci, and up to 2 septate, it cannot be O. quaestiformis, the alternative which has also also mostly much more curved spores.

Originally I found O. septispora on Melilotus but in later years finds were mainly on Phragmites. However, we finally had it also on Typha, Juglans and Lonicera. So indeed a new substrate.

Please let me know the collection data.

Re:Orbilia spec. 2
Hi,

thanks to both of you! Here is another picture of an ascus.

Best wishes,

Re:Orbilia spec. 2
yes, the septa are clearly seen, only the ascus is perhaps not really turgescent (difficult to say), at least there is one spore at the very base, maybe the ascus base was broken. Perhaps the ascus was alive when unbroken, but this cannot be said with certainty.

i am quite sure you will find mature living asci when making a hand section.
