Hola a todosI found this small Tarzetta that seemed strange to me from the beginning, different from the T. catinus I have seen other times.
The size is very small, the largest specimen is 13 mm in diameter, the ascocarp is sessile and the hymenium is more grayish than the excipulum.
Also the habitat is different from the one I usually find T. catinus, this time it is in muddy soil, next to a stream with Quercus ilex, the PH of the soil is acidic.
I have been looking for possibilities and I have found a taxon that I did not know called T. quercus-ilicis. What is your opinion?. If there is any microscopic difference with T. catinus I could look it under a microscope

Re : Tarzetta sp
Hola Luis, creo que vas a necesitar micro. Desde de mi poco conocimiento, y mi humilde opinión,otra posibilidad en un habitat parecido de Q.ilex y Q.pyrenaica que determino Enrique Rubio hace unos meses, es T.gaillardiana, puedes ver la micro en su pagina de Facebook del C.E.M.AS. Un abrazo

Re : Tarzetta sp
Hello Luis.
Indeed T. quercus-ilicis is a sessile species with a greyish hymenium. Without microscopic data, it is hard to say if your collection could fit with this species.
