Sclerotinia & Ficaria
Michel Hairaud, 03-03-2022 09:18
Michel HairaudBonjour, 

Voici une planche de Sclerotinia récolté parmi des Ficaria. Les spores de taille 14-16 x 5,5-6,5 µm sont binucléées et j'aimerais savoir si le taxon nommé S. binucleata on Ficaria dans les dossiers de Zotto a pu être confirmé comme  une espèce distincte de S. sclerotiorum . 

Here is plate after a collection of Sclerotinia linked with Ficaria . Spores are bi-nucleate and I would like to know whether it has been formelly separated from S. sclerotiorum (also bi-nucleate and with c.a. same spores) . This species is currently presented under file S. binucleata on Ficaria in Zotto's files. 

Merci. Amitiés pacifiques à tous 
Michel

Re : Sclerotinia & Ficaria
Hi Michel

the microscopy is indeed very similar. Genetically it is sharply separated, also by the much larger apo diameter. Can you tell me the diameter here?

My artticle on this is under work, and I would be pleased include your find in the listed specimens, if you give me coordinates, date and the finder.

Re : Sclerotinia & Ficaria
Thanks Zotto, 
The apos are up to 1,5 cm large . I found it at France; Augé , lieu-dit Bois Aigu 28 02 2022.

Re : Sclerotinia & Ficaria
Hola Michel, Zotto:

Por si fuera de vuestro interés os facilito datos de esta especie de mis colecciones:

Ubicacion: Isla sur del río Miño, Rábade-Lugo, Galicia, España (NW)

Fechas recolección: 22-24-29 abril 2018

43º08'38.69''N   7º36'08.30''W altitud 404 m.s.n.m.

En este lugar se trata de una especie muy frecuente; y si fuera de vuestro interés tener material fresco podría acercarme a comprobarlo; aunque desconozco si en éstas fechas tempranas pueden haber salido ya.

Saludos cordiales y paz para todos

Re : Sclerotinia & Ficaria
Hola Antonio

thanks for this. I am now uncertain which species you have, do you have any micros?

The leaves belong to which plant?

Was there any Ficaria and/or Anemone?

Re : Sclerotinia & Ficaria
Gran observador Zotto!, las dos fotos inferiores estan acompañadas de hojas de Anemona, las coloque yo tras recorrer muchos metros hasta encontrar una, pues no abunda en la isla. Las coloqué porque pensaba que podría tratarse de D.tuberosa, pero al llegar a casa me di cuenta del error por haber colocado esa planta, en lugar de Ranunculus ficaria. Por lo que respecta a la micrografía, creo que fué la primera especie que estudié, y sumando que no sabía utilizar correctamente el microscopio, ni usar reactivos y colorantes adecuados, y tampoco tenia cámara de captura...pues no te esperes algo decente, pero al menos espero que ayude.

Re : Sclerotinia & Ficaria
Indeed it is binucleata. When enhancing the contrast it becomes more clear, though unshar.

Re : Sclerotinia & Ficaria
Many yers ago I had found a similar species. I had no microscope nor camera, but I already knew Dumontinia tuberosa well enough to know that it was another thing. It was the beginning of the spring, fruiting time of the first Morchella, and searching for morels, between Ranunculus and Eranthis hiemalis I found several spots of that Sclerotinia.

This post makes me want to go search for it, but the whether is very dry here, no rains since the beginning of december...

Maybe next year.

Regards

Re : Sclerotinia & Ficaria
Bonsoir,
Récolte est du 28/3/018 parmi des ficaires et un peu de lierre terrestre.
Apothécies >1cm, ascospores : 12.5-14.5 / 6.5-7.5 µm.
Je l'avais déterminée comme Sclerotinia sclerotiorum mais à la lecture des commentaires,
avec les deux noyaux ce serait peut-être S. binucleata ?

Merci pour vos avis

Jean-Claude

Re : Sclerotinia & Ficaria
Oui Jean Claude, 
la taille des apothécies, les spores binucléées et la relation avec les ficaires vont très bien.

Re : Sclerotinia & Ficaria
I agree. The year was 2018? I could include this find in my MS if you send me coordinates. You found it?
