Green coated Dothideo
Adam Polhorský, 09-04-2016 17:15
Hello,

this fungus (0,9-1,2mm) was found abundantly on a dead fallen branches of Quercus sp., often hiding under bark. I am not aware of genus/species with such colouring- assume its not artificial.

Spores: hyaline dictyospores with 7 horizontal and 1 vertical septa
            (18) 20-30 (32) x 8-12µm

Thank you for your help,
Adam

Re : Green coated Dothideo
Hola Adam.

Creo que su hongo puede ser Thyronectria, aunque habría que mirar algunas cosas más, como Paráfisis apicales, paredes de los peritecios, reacción en KOH, etc. En ramas de Quercus ilex crece T. giennensis con esporas que se podrían ajustar a sus medidas, pero son de color marrón-verdoso.

Tal vez le pueda ayudar Walter Jaklitsch.

Saludos.
Salvador.

Re : Green coated Dothideo
Hi Adam,

have a look at this publication on the genus mentioned by Salvador, containing a key, descriptions, and illustrations: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4312933/

Best wishes,
Gernot

Re : Green coated Dothideo
Thank you very much Salvador and Gernot! I read through the paper and  microscopicaly Thyronectria rhodochlora is a good fit, but host is different. Seems to be a difficult genus, Hermann Voglmayr will take a closer look.
