Bonjour à toutes et tous,Pourriez-vous me donner
Hola a todos.
Subo unas fotos de un asco que he encontrado sobre hojas de Quercus.
Miden hasta 400 micras y al principio son blanquecinos, luego en seguida toman tonos amarillentos y al secarse son amarillos.
Ascas amiloides, tetraspóricas.
Paráfisis con una gran gota amarillenta en tramo apical.
Esporas que al madurar forman 1 septo central trasversal, de 13,5-17,5 x 3,2-4 micras.
PodrÃa ser la misma especie de esta otra recolecta. http://www.ascofrance.com/search_forum/45203#
¿Qué les parece?
Gracias por sus respuestas.

I think this is similar to the "Calycellina araneotincta?"-thread/collection you presented last year.
Spores maybe not exactly like, but we can't be that far away I think. Are there any chances of you sending me some material? If yes, I'll send you details in email.
Timo
In your two samples, Ruben, the substrate seems to be Q. ilex too?
I have placed the three samples in the folder "Hyalopeziza-like" in Calycellina:
https://drive.google.com/drive/folders/0B5SeyOEkxxZhdHZWRjhnUTV0Qkk
C. araneocincta on Betula leaves has distinctly narrower spores. It seems quite normal that Calycellina-spores get 1-septate when overmature, but never inside the living asci.

Hola a todos.
Gracias por sus respuestas, Timo, Zotto.
Timo, tengo 6 hojitas con muchos ejemplares en cada una, si quiere puedo enviarle 3 ó 4 hojas. ¿Quiere las hojas ya secas o alguna en fresco? Las tengo en frigorÃfico desde el sábado.
Saludos
Rubén
3 or 4 leaves should be enough. I recommend you keep one leaf with the youngest/most fresh fruitbodies alive and send it together with maybe other fresh Quercus leafs or similar organic cushion in a big enough plastic bag. This way it just might make it alive to Stockholm. Dry the others and put them in a paperbag or similar. If the fresh apos won't shoot I should be able to extract from dried fruitbodies.
