En los tallos viejos del hinojo silvestre (Foeniculum vulgare)

Castillo JosebaHe recibido unas muestras secas de esta especie recolectada en los tallos viejos del hinojo silvestre (Foeniculum vulgare).

No tengo idea de por donde mirar


A ver si hay alguna sugerencia


Saludos
Joseba

This looks like a very interesting fungus, but I have no idea. Do you have a closeup photo of the living paraphyses?

The 2-spores asci reminded me of Didymascella on Thuja, but there the spores have an eccentrial septum.

Is the apothecium closed by a covering layer that splits into teeth and opens when hydrated for some minutes?

Hola Zotto

No me doy cuenta de haber visto parafisis...  tendré que mirar mejor


Si  son como discos y al ponerlos el agua en el porta  al rato comienzan a abrirse y se ven salir las esporas


Seguiré mirando

But your macros are in dry state??

On your last photo I think I see paraphyses.

El material es seco y lo rehidrato sobre el porta, la parte que voy a usar


No soy capaz de ver parafisis en estas fotos.... supongo que si los hay no se cual son

Can you send me the last collage by Email?

It would important to make a macrophoto of a fully hydrated apo at maximum possible magnification. I know this is difficult, the water disturbs and one has to find the exact time when it is still wet but only internally.

Here I suppose these were refractive vacuoles before you added Congo.

Oh, this is reasonable! The species was also treated here:


I conclude the apothecoid ascomata are collapsed cleistothecia, collapsed because dry.

Anyway I wonder what these paraphyses are that I saw. And what kind of content they have.

Since Erysiphales are considered related with Helotiales in the Leotiomycetes, I wonder about paraphyses.

What this abundant white felt might be? Seems then to belong to the fungus.
