Chlorociboria ? on Filipendula ulmaria
Marja Pennanen, 06-09-2016 11:37
Hello forum,

once again I did not find a solution, when looking for a determination to my finding.

These bluish ones color the stem of Filipendula blue and are short stipate, up to 0,7 mm wide.
The spores are about 7-9x2-3 and have a couple of small droplets.
The asci are about 55-70x7-8, IKI- and paraphyses are septate, about 2 micrometers wide.
NM1 tells, that Chlorociboria are found on woody substrates and should have amyloid asci, but to my seeing these were not. So, is there some other genus fitting better or different species in Chlorociboria?

Curiously: Marja

should be Chlorociboria aeruginella

Dear Marja,


this should be C. aeruginella. I found it once in Germany and published about it. It also grew on Filipendula, but it seems to grow on other substrates, too. Surely a rare species.


Best regards from Lothar

Re : Chlorociboria ? on Filipendula ulmaria

I just see my spores and asci were a bit larger than your measurements are. Did you examine living material?


Best regards fom Lothar

I think the spores are o.k. I have *7-15 x 2.5-3.

Hi Lothar, Zotto,

thank you.

I have found C. aeruginella on Salix leaves ealier, but the species is not included in NM1, so I have no description of it.

Lothar, I study only fresh ascomycete specimen in snowless season and interesting ones as soon as possible, the substrate made this interesting ;)
