¿Alguien sabe el nombre de estos conidiomas, o me puede indicar por donde buscar?
Gracias.
Crece en Quercus ilex y los conidios son de (22,5-)24,5-29,5(-32,5) × (20,5-)22,5-25,5(-27,5) µm ligeramente granulosos y envueltos en una masa gelatinosa.
Saludos.
Salvador.

Re : Conidiomas
Very impressive! Was it on leaves or wood?
I really do not know, but perhaps Harknessia or something related?

Re : Conidiomas
Hi Joey
I am a bit involved in this matter for some reason. The fungus grew on an attached corticated branch of Quercus ilex, and the fruitbody is a sporodochium that looks like this:
I was unable to find anything well-fitting in Genera of Hyphomycetes or Ellis & Ellis.
I guess Harknessia is a coelomycetous genus on leaves, apparently connected to Dothideales? It looks really similar, what I have seen in the web, though lacking the gel sheath.

Re : Conidiomas
Harknessia is now in Harknessiaceae (Diaporthales).
I wondered if it was pycnidial or sporodochial... some Harknessia spp. are described as stromatic but I'm not sure if there are sporodochial spp.
The conidia remind me of Harknessia but the sheath is very distinct. Harknessia podocarpi has a thin gelatinous sheath but I flipped through Nag Ray & DiCosmo's monograph but did not see anything with these characters. Have you observed pale longitudinal bands in the conidia (like a germ slit)?
I'll look through the literature a bit, this is so distinctive...

Re : Conidiomas
Hola Joey,Muchas gracias.
No hay ninguna banda longitudinal ni hendidura, solo lo que parecen ser pequeñas berrugas.
Tomás, tu estabas presente cuando lo recogí.

Re : Conidiomas
Dear Salvador
If possible, please send me a subsample of this collection. I would really love to culture it to see if we can work out where it fits in phylogenetically. Its really a very impressive fungus, and I would love to try and help resolve this puzzle!
All of the best
