Mlcoch Patrik, 11-04-2017 17:38
Mlcoch PatrikGood day everyone on this web,
I have problem with determination my collection S. sclerotiorum. I haven't needed bibliography about this genus. I found several collections:

Asci cylindric, 8-spore, 118 - 152 x 7,9 - 9,2 um, spores elipsoid, (8,7)9,2 - 13,8(15) x 4,5 - 7,5 um, Q = 2,1. Can by this collection S. sclerotiorum?

Hi Patrik,
if the sclerotia were embedded within a herb stem, another genus (e.g. Botryotinia) might be a better choice in my opinion. Did you browse Zotto's folder of Sclerotiniaceae? https://drive.google.com/drive/folders/0B5SeyOEkxxZhNFRCWHBfY3h2SW8

Thank you, but I have this Zotto's folder. 
 if the sclerotia were embedded within a herb stem, this weren´t evident. Good type is for example Botryotinia ficariae, however something morphology characteristic looking to the genus Sclerotinia - Sclerotinia sclerotiorum (for example https://drive.google.com/drive/folders/0B5SeyOEkxxZhZzZQRUY0ZW4xY1U .

PS: You will notice, that in Zotto's folder are separated taxa S. sclerotiorum and S. ficariae. S. ficariae is determinated as 'Sclerotinia binucleospora on Ficaria' and also in somewhere literature and web, so that S. ficariae isn´t synonymy of S. sclerotiorum.

Re : Sclerotinia sclerotiorum and S. ficariae after the second
Yes, I never said they were (synonymous). And usually I avoid using the name S. ficariae at all. I guess I better stay with operculates which I understand a little bit better. :-)

Yes, I was only point out on the webs, for example nahuby.sk or ohoubach.cz, where they have badly. I will must it write them. I haven't enough material yet.
