Ciboria spec. on ?soil

Björn WergenHello,

during my last expedition in the "Nationalpark Eifel", Germany, I found something interesting, just one fruitbody which looks like a Ciboria-species, but I am not sure if it is. With Medardi-Key (Ascomiteci d'Italia) it goes up to a "Ciboria polygoni-vivipari", which grows on soil and between mosses. Also spores are very similar...but I have no further literatur for it and that is the reason I am asking here ;) as always ^^

Fruitbody about 3-12 mm, cupulate with a short stalk, grey-brown to ochraceous, similar to Ciboria amentacea.
Spores 12,5 - 15 x 4-4,5, ellipsoid, smooth, with 2-3 bigger guttules and several smaller ones (OCI: 4-5). Asci with 8 spores. Paraphyses filiform, no swollen apex, without remarkable guttules.
I am sorry for bad description, I hadn't any chemical utilities when I found this "Ciboria", now I have some ;)

Well the fruitbody seems to grow on wet soil between mosses, I checked it out but I didn't found any plant debris...

Is it a Ciboria? Or perhaps something near Ciboria? Like Ciborinia? I checked my database but it didn't help :(

thanks for help,
cheers, Kazuya

Dear Kazuya,

we had already a discussion about this species: It is Discinella boudieri, and Geogoryne variispora is something very similar.

Hope you can check some features: Ascus reactio in Lugol (without KOH) should be pale or bright red at the apex. The apothecium should be gelatinous. Try a section, the excipulum is not a globulosa as in Ciboria, but a porrecta, externally covered by much gel.

C. polygoni-vivipari grows on seeds, and I saw this species recently in Lapland.

Could you please tell me the exact locality and datw when you found it?

Here you see the difference: above: Ciboria polyg.-viv., below: D. boudieri.

Thanks

Zotto

Re:Ciboria spec. on ?soil
Hi Zotto,

leider hab ich von dieser Art nichts mehr übrig, es gab nur den einen Fruchtkörper, das war am 22.10.2010 im Bereich des Nationalparks Eifel bei Dreiborn. Die genaue Fundstelle schau ich mir demnächst aber nochmal an, vielleicht finde ich noch welche, hab jetzt nämlich Chemie hier und da würde ich das gerne mal alles testen ;)

vielen dank für die Hilfe, Discinella hatte ich so eigentlich nicht erwartet.

Viele Grüße,
Kazuya
