Hi to everybodyI would appreciate any assistance r
I have here a Calycina sp. which I cannot determine.
My first idea was Calycina herbarum, but the IKI reaction was blue instead of red.
Or can C. herbarum also have a red IKI reaction ?
best regards,
Thorben
C. herbarum reacts blue at low and red at high concentration. This is typical C. herbarum.
Thank you for this information, because I saw everywhere on the Internet only the red reaction in Lugol.
That's why I thought there was only the red reaction.
best regards,
Thorben
