en rama de avellano (Corilus), los apotecios de 318-350 µ, saliendo de debajo de la cortezaA ver si hay alguna sugerencia
Joseba
Hi Joseba,
this is a Pezicula, maybe close to P. cinnamomea. But what do I read? You use Melzers reagent. I rarely use this, and never with discomycetes. Use IKI (or "Barals solution") then we will see if the porus is really negative (what I do not believe) or red.
Best regards from Lothar
I can only urge you to use Lugol. Presumably a Pezicula, and the ascus apex should stain deep red. f you don't have Lugol, apply KOH and afterwards, after removin with water, add Melzer.
Zotto
Tengo IKI y tambien Lugol, Usaré IKI ..... gracias
Joseba
C'est manifestement un Pezicula et il est normal que tu n'aies pas de réaction avec le Melzer car il s'agit certainement d'une réaction hémiamyloïde (rouge avec IKI et bleue avec un prétraitement à la potasse)
AMitiés
Michel
Ah, les réponses de Lothar et Zotto sont arrivées pendant que je répondais..
El resultado es negativo
Saludos
I have the same problem with IKI, (-). Can it be that here frost (10 degrees below zero) affects the result ?
Greetings Peter.
The last pics do not show the iodine, the plasma must be yellow, otherwise one cannot be sure. Hemiamyloid reactions need a bit higher concentrations, but 0.2% iodine in the preparation should be enough, better is 0.5%
Igual tienes el IKI hecho polvo, mira a ver si tiñe de color azul casi negro una miga de pan.
