What could this be?

What could this be? Fromm Torsten Richter

Any idea? Ophiobolus, Pseudohalonectria, Gnomonia, or even Ophiognomonia?

Re : What could this be?

Hi Peter,

I would add Gaeumannomyces to your list of possibilities. Ophiobolus it cannot be, whereas Magnaporthaceae look promising to me.

Kind regards

Mathias

Re : What could this be?

Thanks for the tip, Mathias. However, all Gaeumannomyces species have much longer spores.

Hi Peter,

Ophioceras is another option.

Already tested this species, Bernard. No results.
