Probablemente Requienella fraxini, que crece en la corteza de Fraxinus.

Saludos.
Salvador.

Hi,

I think this should be Requienella fraxini.

Yes, Requienella fraxini. Apparently widespread on Fraxinus in southern Norway, but overlooked until recently. For details see: http://www.ingentaconnect.com/content/nhn/pimj/2016/00000037/00000001/art00006
