A microfungus on Geum urbanum

I had a look at this leaf spot on Geum urbanum. The minute pseudothecia? seem to be immersed, only 0.05mm across (50um) apparently producing brown oval spores 6-7 x 3-4. Looking at Ellis and Ellis, or the asscoiated species list in the FRDBI didn't help. The leaf spot - possibly Ramularia gei - also didn't appear in the FRDBI associated species. Nothing looked likely from plurivorous fungi on herbaceous plants in Ellis and Ellis. Is this a no-hoper?

Peut-être la forme conidienne (Glaeosporium fragariae) de Gnomonia fragariae.
