Callycellina??

Rubén Martínez-Gil, 17-01-2017 00:25

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.

Podría ser la misma especie de esta otra recolecta. http://www.ascofrance.com/search_forum/45203#

¿Qué les parece?

Gracias por sus respuestas.

Re : Callycellina??

Hello,

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.

Re : Callycellina??

There is a third collection made by Tomas Illescas last year on Quercus ilex.

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.

Re : Callycellina??

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 frigorífico desde el sábado.

Saludos

Rubén

Re : Callycellina??

Hola,
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.
