Small orange disco
Masanori Kutsuna, 28-01-2013 04:54
Hello, everyone

I found small orange disco on stem of Miscanthus sinensis in October, Japan.


Apothecia aboud 1 mm., sessile, outer surface brownish.
Ectal excipulum similar to Mollisia, consisting of globular cells, brown.
Medullary excipulum hyaline.
Asci: IKI+ (red), 74-92 x 7.4-8.5 microns
Paraphyses: continuous refractive, pale orange.
Ascospores: 16.3-21.5 x 2.6-3.7 microns.


Is it Mollisia?

Re : Small orange disco
Hi Masanori, 

Your fungus looks very much like Mollisia aurantioviolascens, a non yet published name which you can find in Andreas Gminder's key .
You can try the KOH reaction , violet .

Amitiés
Michel

Re : Small orange disco
Hi Michel,

Thank you for your quick reply.
Hymenium turns violet with KOH.
I think "M. aurantioviolascens" differs in spore size..  

Regards.
