In northwestern Europe, P. margaritatus can be recognised out of 17 species in the field by the black stripes at each side of the abdomen (not always present!), the rows of oblique white bristly hairs at the abdomen and the Xysticus-like shape of the abdomen. There are two variants, this should be the grey one (the most boring one

) But I don't know if there are similar spiders in Romania. This spider is used to live at the bark of trees, covered with lichens. Sometimes also on the leaves.
