Hello all,

Found on Gorse, Ulex europaeus but the closest I've managed is a Diatrypaceae and possibly Eutypa or Eutypella?

Stroma were brownish, ostioles protruding. Spores +/- curved, most with a small guttule at each end, (8)10-12(15) x 2.5(3) µm.

Help appreciated!
With regards,
Jenny

Re : Diatrypaceae - Eutypa, Eutypella?

Hi Enrique - I'm only slowly becoming familiar with mycological terms but I think the photograph below shows it as whitish?

I've found this fungus on most of the Ulex I've collected specimens from on a coastal heath in southern England.

Hi Jenny,
the internal structure is more easily seen on a vertical section.
Cheers,
Jacques

Hi Jenny

It's possible, but Jacques's pic show us perfectly what the white entostroma is.

Please, try again

Re : Diatrypaceae - Eutypa, Eutypella?

Thank you Jacques for your help and Enrique for your patience! I've added a photograph of a vertical section, though the quality is poor.

Re : Diatrypaceae - Eutypa, Eutypella?

Hi Jenny

I think the entostroma is withish. So Eutypella leprosa could be a good choice
