Calycina sp. on Impatiens glandulifera
Thorben Hülsewig, 13-10-2019 14:31
Hi there,

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

Hallo Thorben

C. herbarum reacts blue at low and red at high concentration. This is typical C. herbarum.

Hallo Zotto,

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

Das ist aber erfreulich, dass Lugol so verbreitet genutzt wird :-))
