Hola Enrique.
Podría tratarse de la Pirottaea veneta.
Nosotros la tenemos sobre tallos secos de Heleborus viridis.
Saludos, Javier.

Re:Pirottaea on umbelliferae old stems
I tried Nannfeldt's key and do not arrive at a satisfying result. P. veneta is only given for Helleborus. P. senecionis would be another choice, but here only various Asteraceae are given as hosts. Are you sure with Apiaceae, and which genus occurs there?

Re:Pirottaea on umbelliferae old stems
No, Zotto. I don't know the sustrate. Thank you for your attempt.
Gracias Javi. En principio la macro-micro es bastante similar a Pirottaea veneta, también muy corriente por aquí. Pero el hábitat sobre Helleborus parece muy restrictivo.
Gracias
