Re:Rustroemia firma?
Dear Vasileios
that is a good question. R. firma has wider spores (*15-20 x 5-6.5 µm). Yours look too narrow (though alive), so I don't think it is R. firma. Could you search for overmature spores, do they get 3 septa? Probably they procude small conidia like typical R. firma. You could also look for the excipulum, is it of thin-walled prismatic cells or gelatinised?
Asci are probably strongly blue in IKI and with croziers, but this should also be checked.
