Bitunicate? on ? Lysimachia, southern Sweden, aug 2017
Thomas Læssøe, 23-08-2017 13:59
A presumed erumpent unilocular bitunicate on herbaceous stem, presumed Lysimachia with abundant "spores" but no centrum structures. Spores hyaline, "5"-septate with huge globules, 40-60 x 17-22 µm.
Somebody may know this one based on spores alone?
cheers

Re : Bitunicate? on ? Lysimachia, southern Sweden, aug 2017
Hi Sven-Åke and Thomas,
in absence of further data my answer can only be tentative but I would suggest to look into Halosphaeriaceae where this kind of spore is not uncommon. Asci in that genus are rapidly evanescent but they are fairly typical if you can observe a barely mature ascoma. The family is typically marine or in freshwater, can it be the case here?
The spores of Halosphaeriaceae often have conspicuous appendages, which is not the case here but they seem to be surrounded by a wide sheath, am I wrong?
Good luck,
Jacques

Re : Bitunicate? on ? Lysimachia, southern Sweden, aug 2017
you are for sure right about the gel sheath and your suggestion also explains the missing centrum structures, asci etc. Lysimachia normally grow in wet freshwater sites, so I guess your suggestion is worth exploring.

Thanks
