four-spored Ciboria (?)
Andreas Gminder, 20-06-2023 20:51
Andreas GminderDear collegues,

today I found one apothecium of a brown ?Ciboria with four-spored asci.
Spores are 9-11 x 4,5-4,8 µm, no oil content.
Asci 75-80 x 6-7 µm, with crouiers, porus reaction faintly blue (IKI 1)
Excipulum textura globulosa.

The Apothezium was seated directly on a blackend tiny twig of Alnus, lying in the mud. There was no sclerotium.
The stipe was quite thick and the surface was a bit furfuraceous. Microscopically there were tufts of roundish cells on the stipitipellis.

The cup looked like a nail head.

I have no more informations, as the fruitbody vanished during examination ....
Anyone an idea though?
thank you and all the best,Andreas

Hello Andreas, 
I would suggest there was a small black sclerotium in the mud - compare Sclerotinia capillipes.
Yours, Lothar

Re : four-spored Ciboria (?)
Hello,
I was thinking of that too, but I took the specimen with the twig and I examined it under the dissecting microscope - it was fully attached to the twig and there was no sclerotium, also not inside the wood.
Moreover, I know capillipes with a thin stipe which is sometimes bent, and the stipe is smooth. In my collection the stipe was thickset and furfuraceous and there were tufts of globose cells like caulocystidia.
all the best,
Andreas

Re : four-spored Ciboria (?)
by the way: I don't find capillipes in Zottos folders, did that species change name?

all the best,
Andreas

Hi Andreas

did you compare Ciboria acerina?

"Ciborinia capillipes" is in the Scleromitrula folder.

Re : four-spored Ciboria (?)
Hello Zotto,

I excluded acerina because the spore width was only 4,5-4,8 µm and acerina should have broader spores
otherwise it would fit quite well.

thanks also for the hint to capillipes.

all the best,

Andreas

Re : four-spored Ciboria (?)
Hello,

I checked the capillipes folder and I think now that Lothar had the correct idea. There are fotos matching exactly my findig from today, especially what concerns that nail-like habit. the microscopical details fit well. So the sclerotium might have been indeed overlooked, though I did really care not to overlook it .....

all the best,Andreas
