Small orange discs but no octospora
carl van den broeck, 14-11-2024 12:06
carl van den broeckOn November 8th I found very small orange discs stuck together along the edge of a pond in the Belgian dunes. They were on bare ground near Bryum sp. which is why I thought I was dealing with Octospora s.l.. When examining them with a microscope I saw septate cilia which does not occur in Octospora s.l.. No dung was visible in the area. Operculate ascen, 8-spored operculate ascen, oval to ovate smooth spores 14-16 x 8-9 mu, q = 1.7, paraphyses with capitate head, hyaline septate cilia at the edge (hardly visible with a magnifying glass). 99% of the spores contain one drop. Strange spores can be seen on one photo, but I think this is a contamination. Can anyone point me in the right direction? Thanks!

Re : Small orange discs but no octospora
Why do exclude an Octospora species?

Re : Small orange discs but no octospora
Hoi Carl,

Is there perhaps charcoal nearby, then Neottiella hetieri could be a possibility?

Kind regards,

François

Re : Small orange discs but no octospora
I have never identified an Octospora with cilia and the keys do not give me an acceptable species.

Re : Small orange discs but no octospora
Thanks Francois! In the meantime I found a key of Moyne of Octospora s.l. and relatives with hairy edges. I think your proposal comes close!

En recherchant sur Google 'Octospora et setae', je trouverai  Octosporopsis, pour mois inconnu.

Re : Small orange discs but no octospora
From a phylogenetic point of view, and also morpholgically, Octosporopsis is different from Octospora (s. lato).
The presence of setae/hairs at the margin is no more a character useful to exclude a species from Octospora s. lato.
Neottiella hetieri must be considered as an Octospora, and "true" Neottiella are associated to Polytrichum.

Re : Small orange discs but no octospora
Thanks for your reactions. On http://www.octospora.de/Ohetieri.htm  I find description and pictures that  morfological perfectly match my find.
