Acoma histerotecio carbonaceo, de 0,5 a 1,5mm de largo, elipsoide, no esta logintudinalmente estriado, con surco longitudinal que se ensancha en la madurez, en grupos y juntadose con otros.
Hamatecio, forma una matriz gelatinosa, parafisis de 1 a 2 micrómetros de ancho, no aprecio septos ni ramificaciones.
Ascos clavados, octosporicos entre 58 y 68 de largo X 12 y 17 de ancho.
Ascosporas fragmosporas, fusiformes hialinas siempre he contado 5 septos, entre 20 y 28 largo X 3 y 4 ancho micrómetros.
alguna idea?
gracias

Hi Angel,
The closest species are pteridicolous, and it's slightly different. So that one on Ceratonia is probably new.
Alain
for me it looks like a lichen: the appearance of the hysterothecium, the ascus structure, the iodine reaction, the algae which are shown on the first two pictures. But maybe I'm wrong... I'm not a specialist...
Best, Uwe
Hi Uwe,
not impossible as you said. I didn't see really the idione reaction on Angel's photo, but the question must be put.
Angel, can you check there isn't thallus ?
Alain

haciendo secciones transversales no aprecio ningun talo, me parece el aspecto de un histerotecio de Hysterial tipico pero tampoco soy ningún especialista.
gracias por vuestras opiniones.
un saludo

I see on picture six a red reaction of the ascus, similar to reactions which I saw in lichens. I didn't know these red reaction from other members of the Hysteriaceae. That's why I thought of a lichen. But mabye I'm wrong...
Best, Uwe
You're probably right Uwe. The genus Opegrapha could be a good way for research. For example : http://www.afl-lichenologie.fr/Photos_AFL/Photos_AFL_O/Texte_O/Opegrapha_niveoatra.htm

Gracias por vuestra ayuda Uwe, Alain
