Pseudotecios of up to 250um of diameter, smoothed, on leaf of quercus.
Ascas of 40-50 x 10um.
Spores elipsoidales, gutuladas, of 10 x 4
I do not observe hamatecio
I have thought that it can belong to Botryosphaeriacea, and inside this family belong to the genre Guignardia.
Might it be??
Thank you in advance?
Susana

Re : Botryosphaeriaceae?
Hello Susana:
I am not familiar with this fungus but you might want to check Anisostomula quercus-ilicis (Trav.) v Hohn. or Guignardia punctoidea (Cooke) Schroter. The former is in "Amerosporen Pyrenomyceten" (v. Arx & Muller 1954), the latter in Ellis & Ellis Microfungi on Land Plants.
At least it's a start.
Best of luck.

Re : Re : Botryosphaeriaceae?
Hi Adrian:
I have no literature you mention and have not found anything on internet practically. For G. puntoidea indicate somewhat larger spores (10-16 x 4-6).
In A. quecus-ilicis nothing found.

Re : Re : Botryosphaeriaceae?
I am sorry but I only have paper copies of the references I mentioned and cannot send by email.
In Ellis & Ellis Microfungi of Land Plants they cite spore size of 8-13x3-5u for Guignardia punctoidea. A synonym for Anisostomula quercus-ilicis is Guignardia quercus-ilicis.
Perhaps some kind folks on the forum could provide further references via the email.
I am afraid I can't help any further.

Re : Re : Botryosphaeriaceae?
Hello
Thank you very much to you both.
I see that the document that you send the spore size fits.
However, without more information I can not say that is G. puntoidea.
I will file as possible Guignardia sp.
