I'm conducting a mycological inventory in two greenhouses in a park in downtown Lyon, one tropical and one temperate. This ascomycetes was found in the second. The substrate is of undefined origin. In the immediate area, there were Camellia japonica and Alpinia caerulea. The spore size is similar to those of Ciboria latipes, which grows on Rubus chamaemorus, although the original description doesn't mention amyloid asci. There are probably other hypotheses, and I'll sequence it, like everything I find in these greenhouses. If you have other hypotheses, they're welcome. Thank you.
Spores size :
(9,1) 9,7 - 11,8 (13,6) × (4,2) 4,4 - 5,7 (5,8) µm
Q = (1,6) 1,9 - 2,3 (2,7) ; N = 41
Me = 10,9 × 5,2 µm ; Qe = 2,1
Q = (1,6) 1,9 - 2,3 (2,7) ; N = 41
Me = 10,9 × 5,2 µm ; Qe = 2,1
Ascis size :
(108,0) 108,6 - 115,4 (117,2) × (5,4) 6,1 - 6,85 (6,9) µm
Q = (15,8) 16,0 - 18,6 (20,9) ; N = 9
Me = 112,5 × 6,4 µm ; Qe = 17,6
Q = (15,8) 16,0 - 18,6 (20,9) ; N = 9
Me = 112,5 × 6,4 µm ; Qe = 17,6

Bonjour Sebastien, bienvenue sur Ascofrance,
De mémoire, il me semble que Ciborinia camelliae possède certains des caractères décrits
Amitiés Michel

Re : Ciboria / Rutstroemia (?)
Bonjour,
en effet, cela convient très bien !
Sous camellia , ciborinia camilliae !
bonne journée

Re : Ciboria / Rutstroemia (?)
Interesting collection! I suggest to illustrate the living paraphyses. There are three sample from 2013 illustrated by Enrique Rubio in which they contain low-refractive VBs. I also see a fantly amyloid medulla with crystals. The spore contents look a bit different there.
Your ascus measurements clearly refer to dead asci. Enrique measured up to *137 x 10 µm.
Sequences (ITS+LSU) from eastern Asia exist in GenBank, so it would be interesting to compare.

Hello !
Thanks for you answer !
Will get back in the greenhouse , they were a lot .
And do what you suggested.
Sébastien

Re : Ciboria / Rutstroemia (?)
Sébastien, s'ils s'agit de C. camelliae, il devrait y avaoir des sclérotes à la base des stipes (enfouis dans l'humus probablement). Nous avons trouvé cette espèce en grand nombre dans un parc en Bretagne (22) avec une très grande collection de camélias , en plein air.
Je dispose d une documentation assez complète

Re : Ciboria / Rutstroemia (?)
Merci ! Oui il y avait des sclérotes et la littéralture est nombreuse sur le sujet , notamment une étude de 2023 en Italie avec la génétique .

Re : Ciboria / Rutstroemia (?)
Dear Sebastien
I am about to finish an article on Scleromitrula/Ciborinia, dealing mainly with Sclerotinia capillipes. The matter about C. camelliae brought me today to realize that Japanese C. camelliae was desribed wth spores of 5.3-7 x 2.5-3.5, so much smaller than yours and Enrique's docus show. I am also curious about the original description of Sclerotinia camelliae Hara (1919) which is, according to Kohn (1979: 399) not the same as S. camelliae Hansen & Thomas which is an obligate synonym of C. camelliae Kohn.
Did you try sequencing of your sample? I am unaware of the recent Italian contribution you mentioned, but I noticed the "unpublished" paper of Saracchi & Pasquali in GenBank (e.g. MW624718). - Ah, I found it : https://www.mdpi.com/2076-2607/11/11/2727

Dear Zotto,
here's Hara's article and an approximate translation (google + deepl combined, but there are still some errors left and I don't the language to correct them).

Re : Ciboria / Rutstroemia (?)
Thank you so much Viktorie!
incredible to have a new species publshed in Chinese.
Surely Species Fungorum is wrong who puts this in synonymy with Ciborinia camelliae Kohn.
I see it has the spore length of Enrique's and Sebastiens fungus, but the width might be erroneous. The Saracchi article does not provide any morphology, regrettably. I fear this article is very difficult to use.
