Pongo fotos de una recolecta sobre madera sin identificar, en bosque mixto de P. nigra, Q. faginea y Q ilex, con hiedras y bastantes arbustos diferentes.
Ascas inoperculadas, amiloides (IKI+), pleurorrincas, de 150-180 x 9-13 micras.
Esporas gutuladas, elipsoidales, de 15-19 x 5,5-7 micras.
Paráfisis filiformes, poco o nada engrosadas en el ápice, septadas, alguna bifurcada en tercio superior, con contenido interno de color pardo.
Gracias por su ayuda
Un saludo
Rubén

Re : Rutstroemia ?
Hi Ruben
this is one of the mysteries of Rutstroemia. Is this R. firma or not? Often R. forma has curved spores, but sometimes like yours, and sometimes mixed.
Are you sure that the last image shows the ectal excipulum? The broader hyphae of the beforelast could rather belong to it. Important would be to know if there is any gel in the ectal excipulum, which is best seen in a section.

Re : Rutstroemia ?
yes, I also suspect that these narrow hyaline hyphae with anastomoses are embedded i n gel and belong to the central layer of the ectal excipulum.
It looks similar to my drawing here. Also Yannick had a find on Betula with such spores (X.2009) or Bernd Fellmann on ?Castanea twig (Toscana, X.07).
Would be interesting to make a DNA study on these different spore types.

Re : Rutstroemia ?
Sí, parece que su dibujo es de una recolecta similar a la mía.
Gracias por todo.
