Hello Rafael,
it is surely not M. hydrophila, which is confined to Phragmites (rarely other grasses may be), has more oil in the spores, a yellow KOH reaction (not always constantly) and masses of cristals in the medulla.
What you have there I can't say. Probably it is what I tend to call M. olivaceocinerea, the most common species of the cinerea-complex. Then you should see a little bit of oil droplets in the spores. If they are really completely empty, then I don't know. I don't think it is M. cinerea ss. str., which has smaller spores (6-9 µm, max. 10 µm long) and a bit different macroscopic appearance.
best regards,
Andreas
la camara del micro no permite captar muchos detalles, pero en los dos polos de las esporas se ven unos gotoitas muy pequeñas

Hola Rafael,
in Mollisia olivaceocinerea the excipulum often becomes olivaceous-greenish with KOH and not grey as in the other Mollisia species. This is not a constant character, but when it is to see, it is a good hint for this species.
Also the hymenium becomes a bit cream coloured when slowly (!) drying. You can see that in the field in older apothecia.
best regards,
Andreas
