Geoglossum fallax??

Hola a todos.


Subo unas fotos de un Geoglossum que encontramos entre hierbas y musgos en talud húmedo.


Miden hasta 6 cm de altura.


Esporas de 4-12 septos.


¿Qué les parece?


Gracias


Rubén

Re : Geoglossum fallax??
Could be fallax indeed but you did not see living asci? The spores in the living asci should always be hyaline, the ejection happens when they are still hyaline - this is a good character of fallax.

Re : Geoglossum fallax??

Hola Zotto.


Sí, yo vi muchas ascas que soltaban esporas hialinas en la preparación.


Envío alguna foto con ascas, vivas, creo.


Saludos y gracias por su ayuda.

Re : Geoglossum fallax??
Yes, on the last pic I see about 4 living asci with hyaline spores, showing vacuole water below the spores and also on the sides between ascus wall and spores.

The ascus with brown spores is clearly dead, the ascus is collapsed (shrunken) and the wall tight with the spores.
