Re : cf Psilachnum

Coud well be, though I miss some 1-septate spores. The substrate looks to me like a dicot, but not sure. Juncus should have chaacteristic cells in the interior, maybe star-like.

Re : cf Psilachnum

Gracia Raul, thank you Zotto,

Substrate unsure.
I did not see septate spores. Maybe lack of maturity ?
