Ascomycet on Clematis vitalba
Matthias Mann, 23-04-2017 11:14
Matthias MannDear Forum,

eaven though the Spores would show a characteristic habit, I cannot determine this fungus. Actually the decission, wether it makes a Cleistothecium (I would think) or a Perithecium is hard for me.
If I would know the systematical possition, I could learn a lot :-).

Thanks for viewing,
Matthias

Re : Ascomycet on Clematis vitalba
Rebentischia caudata.

Systematic position:  Ascomycota, Pezizomycotina, Dothideomycetes, Tubeufiales, Tubeufiaceae, Rebentischia
I  should point out that I found this by the simple expedient of referring to Ellis & Ellis (1997) and then looking up the images on the internet.

Re : Ascomycet on Clematis vitalba
correct spelling is Rebentischia UNIcaudata not caudata

Re : Ascomycet on Clematis vitalba
Dear François,
"caudata" even not listened as synonym in Index Fungorum.

Merci!
Matthias

Re : Ascomycet on Clematis vitalba
Apologies for the inaccuracy.  The mistake is mine, certainly not that of Ellis & Ellis.
