Re : Mollisia 30-09-18
Hmm, I cannot believe such wide spores. But a main probem is: Do the paraphyses contain VBs? I do not see them but there are not enough paraphyses on your pics.

If they contain VBS, and only then you have a Mollisia, you must test the KOH reaction.

Re : Mollisia 30-09-18
No veo en ninguna parafisis VBS.
Que otro genero puede ser ??

Re : Mollisia 30-09-18
That is the good question. Pyrenopeziza on wood, a rare case....

Your micros always have the same magnification, did yi ever ask you for a scale for them in order to remeasure the spores?

Hola Zotto
las fotos su siempre X100 en inmersión de aceite
La escala es un tema que tengo pendiente

Re : Mollisia 30-09-18
If you have the opportunity to use a calibration slide you simply need to take a photo under oil immersion (100x, with oil).

A sample at high altitude with a similar spore size was presented by Yannick Mourgues:

But here the spores were septate.

Re : Mollisia 30-09-18
o.k., but 
1. The thick scale is in your ocular. That scale is not on your pics, so you take your photos through another ocular? Calibration must be done with exactly the same lens combination.
2. You must send me the spore photo of your "Nollisia" along with the scale photo, because ASCOFRANCE reduces the size of the pics at different rates.

Re : Mollisia 30-09-18
La foto es del Movil, esta realizada para ver que esta bien calibrada.

la lente de calibracion esta en un ocular y la camara en el tubo vertical, con la camara no me sale la medicion, 

tengo que retomar lo de colocar escala en las fotos.

como digo siempre estan realizadaas x 100, y periodicamente comprobado que esta escala no varia

Re : Mollisia 30-09-18
o.k., but you must know that measurements from the ocular micrometer are sometimes different between people, and the only way that I can control the measurement if a scale is included in the photo. If you send me a photo of the scale made with your camera in the vertical tube along with a spore photo of that fungus, I will put the scale in the photo and then measure te spores with a ruler.
