Observation MO81510 was very helpfull to the identification of these specimens. The day after of that observation and in a different place I found a group of three specimens, which I was not sure to belong all to the same species, where at least one of them was very similar to the one in that previous observation. I observed the spores of the each and concluded by their form and dimensions that all of them are of the same species and must belong to the species considered in MO81510. This information as well as some more photos from microscopy can be found attached.
