Hola a todos.


Subo unas imágenes de un disco negruzco que hemos encontrado hoy sobre tierra húmeda, en un bosquete de P. halepensis y carrascas,


Tiene esporas esféricas de 14,5-17,5 micras, con verrugas redondeadas muy pequeñas y aisladas.


No vistos croziers, IKI(-).


¿Qué os parece que puede ser?


Gracias por su ayuda.


Rubén

Re : Disco negruzco

Hola de nuevo.


Subo unas imágenes del excípulo ectal y del margen del apotecio, así como de la base de las ascas bifurcada.


Un saludo

Adio Ruben,

I don't know but only for information, see description of Greletia (Smardaea) mülleri, an american species.

Re : Disco negruzco

Gracias Peter, Beñat.


He mirado Greletia mülleri y la ornamentación esporal es parecida y podría encajar, pero la medida esporal es algo menor.


Seguiré buscando.


Un saludo


Rubén

Re : Disco negruzco
Did you consider Marcelleina?
Hope you find the correct name for it.
Sincerely,

Marcelleina pseudoanthracina ?

Re : Disco negruzco
Kaixo Placido,

M. pseudoanthrancina is a Peziza, see fungi non delineati by René.
And spores of it are around 7-8 µm, not 14-17 like here. A big difference, no ?

Agur bero bat,
Beñat

Re : Disco negruzco
Back to this old post...

For a project dedicated to some Marcelleina species, we had the opportunity to sequence Rubén's collection. A paratype of Marcelleina donadinii was also revised and sequenced, and appears to be the same as Rubén's fungus!
Except the spore size, slightly smaller, Ø (12.5) 13-15 µm, in the paratype, the other features agree with Moravec's description (1987). Note that Moravec's drawing of ascospores doesn't correctly render the small warts on the surface (its SEM photos are more informative).
Finally, this species seems to be a member of Discinaceae...
