Xylaria cornu-damae
Joaquin Martin, 29-07-2023 21:46
Hi
On Friday I found this Xylaria on a moss-covered stump.
After doing the micro I found only one species that fits very well with my species Xylaria cornu-damae, american species, and I am surprised not to find collections of this species, or a synonymy, european.
The spores are immature, that's why the green colour, they are supposed to be brown when they mature.
I would like to know your opinion on this.
Thank you.

Re : Xylaria cornu-damae
Parece muy interesante, Joaquín. ¿Por qué no intentas incubarla en una cámara húmeda? ¿En qué provincia española la has encontrado.
Saludos

Re : Xylaria cornu-damae
Hola.

Está recogida en Navarra, en la sierra de Aralar, carretera de Lekunberri al santuario de San Miguel de Aralar, mas o menos por el Km 9.
Saludos Enrique.

Re : Xylaria cornu-damae
very interesting indeed Joaquin.
I don't know X. cornu-damae, which is not reported from Europe. The morphology of the germ slit would be of great help. Xylaria digitata might be considered too.
I would be glad to look into your material if you accept to share a part of it.
Un abrazo,
Jacques
