Xerombrophila crystallifera?
Edvin Johannesen, 30-10-2018 18:22
Edvin JohannesenI suspect that I have Xerombrophila crystallifera, collected in a previously flooded arae with deciduous trees, incl. Salix. Apothecia break through the bark in a fasciculate manner. White pruina on excipulum (crystals). Ectal excipulum (?) cells prismatic. Medullary excipulum gelatinised. Pictures are of crystals and prismatic cells in water. Asci, paraphyses and spores in Congo red. Blue ascus pore in Lugol. All photos 1000x oil imm. Scale 1 micron. Hans-Otto, you described the species (and genus). Can you confirm? I do not have your 2013 paper (would love to have it, if possible).  Thanks.

Thanks a lot (got it by email) :-)

Re : Xerombrophila crystallifera?
By the way, it was found northwest of Trondheim in Mid-Norway, so it would be a significant jump in the known distribution of the species.

Re : Xerombrophila crystallifera?
Yes of course it is this species. You found it this month? Because you figured only dead elements.

I assume it was a standing dead branch? Very probably it was Salix, as always.

Indeed it is the first record from Scandinavia known to me.

Re : Xerombrophila crystallifera?
It was collected in June and sent to me a few weeks ago, so I guess you are right it is all dead. I am not so trained in judging dead or alive.  Thanks for the confirmation! :-)

Re : Xerombrophila crystallifera?
Is your Congo Red aqueous or other? The species survives for some time in the dry state, maybe even months, at least the spores.

Yes, in water. From Micro Science.
