Marcelleina?
Mirek Gryc, 04-12-2020 18:23
Hello all
A friend sent me two collections of small ascomycota found in August, growing on the ground. I have absolutely no idea for them. Microscopic structure similar to Marcelleina, but nowhere can I find a species with such bright colors.
Please help.

Re : Marcelleina?
An albino... or a new species.

Re : Marcelleina?
Hi Nicolas
I don't think this is some kind of albinistic form.
As I wrote, it is not a single collection. From a friend I have two identical collections from a different period and place (photos 1-2, the first, photos 3-4, second). Both microscopically identical.
Microscopic photos made of dry material, so their quality is poor, but will you confirm that it is a species of the genus Marcelleina?
Regards and thank you.
Mirek

Re : Marcelleina?
An albino form can occur at different places if the mycelium has the same genetic anomaly.
But to answer your question, yes, it looks very much like a Marcelleina species, and M. persoonii if I had to name it only based on the spore ornamentation.

Re : Marcelleina?
Thank you, Nicolas, for your opinion on these collections.
Marcelleina is unknown to me, so any comments about her are very valuable.
best regards
