Pyreno on Equisetum

Enrique RubioDo you have some idea that help me with this non-stromatic pseudotecia up to 0.2 mm in diam. inmersed on stems of an Equisetum species? The ascospores are hyaline at first, but pale brownish with age, with the lower cell narrower than the upper one.
Many thanks in advance.

Re : Pyreno on Equisetum
Hi Rubio,

Does those spores have a sheath? If so, this is perhaps Lophiostoma amphibium (Magnes & Hafellner) Aptroot & K.D. Hyde.

Regards,

Bernard

Re : Pyreno on Equisetum
Thank you, Bernard
I can't find any information on this taxon, would you happen to have any?

Hello,

the orig. description is here: https://www.researchgate.net/publication/283923700_Ascomyceten_auf_Gefasspflanzen_an_Ufern_von_Gebirgsseen_in_den_Ostalpen

The new combination was published in this chapter, but I haven't been able to find either the chapter nor the whole book. https://fungi.myspecies.info/content/marine-and-estuarine-species-lophiostoma-and-massarina

Re : Pyreno on Equisetum
I would like to thank you once again for your prompt and comprehensive help, Viktorie.
And also to Bernard, although having read the description of Massarina amphibia, I don't think it can be this species with hyaline spores surrounded by a compact gelatinous sheath.

Re : Pyreno on Equisetum
The size of the spores is larger but this looks very like the image here. I got the name from Holm & Holm "Nordic equiseticolous Pyrenomycetes". They give "Spores sub- fusiform, (12-)16-18 x 4-5 µm" . . .

Best wishes

Chris

Re : Pyreno on Equisetum
Dear Chris.
I had considered that possibility, but the spores of that Didymella are described as hyaline and not brunnescent as in my collection. And the host, although this is quite irrelevant, was not Equisetum silvaticum but E. telmateia.
Finally, I think this collection could be close to Scheuer's concept of Massarina pusillispora, although Massarina is also a genus with hyaline spores. These genera are really complex.
Anyway thank you very much for your opinion.
