Good evening everyone,I recently bred an Ascobolus
I found this Xenonectriella/Pronectria like fungi grwing on Phaeophyscia orbicularis. I think it is Xenonectriella leptaleae (synonym for Pronectria leptaleae). Update: it is now called Xenonectriella physciacearum
The ascomata protrude from the thallus of the host and are appox. 250 um in diameter. young spores are transparent and smooth, 2 celled, broadly ellipsoid, slightly constricted at the septum. Mature spores are light orange/brown and have a tuberculate surface, measuring 12.5 - 14.6 x 7.3 - 9.1 um (n=9). All microscope photos are in K.
Can anyone confirm this is Xenonectriella physciacearum ?
Kind regards,
Niek Schrier
Now called Xenonectriella physciacearum, see attached piece.

Pronectria-amp-Xenonectriella-sur-Physciaceae-Herzogia33--0001.pdfI couldnot download that paper and therefore didnot know it had a new name. I updated the name in the topic and text. It looks like it is Xenonectriella physciacearum as far as I can see for now. We did observed a violet K+ reaction btw.
