Yellow goblet on Equisetum
Marja Pennanen,
20-08-2014 21:35
these beautyful ascos grow on a river bank on Equisetum (fluviatile?) and are about 1 mm high.
I have never met any fungus resembling these!
The spores are about 25-30x6-7 and asci about 110-130x9-11, IKI blue.
Paraphyses have some small guttules and are septate, about 2 micrometers wide and a bit longer than the asci.
Miss even a genus to start looking for determination: Marja

Hi Maria,
Look at Stamnaria genus

Hi Marja
Try this link:
https://www.cubbyusercontent.com/pl/CC%2bAscomycota/_1354d48ffaad4b59bd3ffdbb35915d1f#CC%20Ascomycota/7a%20Helotiales/4b%20Gelatinodiscaceae%2C%20Ombrophiloideae/Stamnaria/laetissima%20%3D%20americana%20amyloid
This is an interesting collection. Hosoya recently wrote a paper on it but misnamed it S. americana, which is a species confined to Equisetum hyemale and has inamyloid asci.
The name laetissima is not yet officially clarified, and it is a suggestion by Erwin Gruber.

Re : Yellow goblet on Equisetum
Dear Zotto,
thank you!
I determibed this as S. americana yesterday evening.
I lack descriptions and noticed, that S. americana had bigger spores than S. persoonii.
Once again I went to forest with my determination ;)
I'm very happy to find pretty ones like these: Marja

I Marja
I think I was stupid. Presently I cannot easily access my images and Cubby does not work properly. But I remember that S. americana s.l. has unstalked apothecia without a distinct collar. So your collection is highly interesting.
I think that Danny Haelewaters has great interest in sequencing your record. So if you have enough apothecia (maybe 2-3 shoud be sufficient for an extract), I would ask him.

Hi,
attached is the protologue for St. americana. Please note the larger asci and the statement "not blue with iodine".

Re : Yellow goblet on Equisetum
Yes, it is inamyloid, and the apos look very different. Equisetum hyemale is a very characteristc species, not to confuse with any other Equisetum. S. americana was only recorded on this host plant with certainty.

Re : Yellow goblet on Equisetum
Martin,
thank you for the description.
Zotto,
the collection is very scanty, but if needed, I can separate some fruitbodies.
I was in a hurry in the collection place. Rain and thunder were coming and I did not study the surroundings propely. But I suppose, that the Equisetum at a river bank is not E. hyemale.

Re : Yellow goblet on Equisetum
Agreed, these yellow goblets are beautiful ascomycetes.
Hello Marja and Zotto, got my access to here back today.
As written to Zotto recently the combination of fruitbodies looking like Stamnaria persoonii and those large fusiform (-falcate) spores is unique, thus would mean a further unknown species.
Marja, you added photos showing empty, possibly even immature? asci, and separate large spores, but no asci containing spores.
Just to be sure, could you prove this again to exclude chances that these spores might belong to another fungus located at the same host?
Your sample has been sent to Danny for sequencing, i am curious for his results and interpretations.
Since the Genus comprises highly host specific species, the ID of the Equisetum is important.
Do you have a chance to collect the same host at same location?
I could do the ID in case i may see enough of the host plants growing there.
Currently i may just guess it is either E. arvense or palustre, despite the latter one is not proved as host to any Stamnaria till now.
In case you liked to compare with S. americana:
