The overall stature of the fruit bodies of P. pelliculosa is generally similar to those of Mycena, Galerina, or Hypholoma.
Smith noted a superficial resemblance to Psathyrella fagicola, based on similarities in the nature of the cap cuticle, the coloring, and the stem base covered in silky fibers.
Psilocybe pelliculosa may be distinguished from Psathyra fagicola by the presence of a partial veil, firm gills, and smaller fruit bodies.
P. pelliculosa is frequently mistaken for the widespread P. semilanceata, but the latter can be distinguished by its larger spores and a conical, papillate cap.
Another similar species is Psilocybe silvatica, and a microscope is needed to reliably distinguish between the two species.
P. silvatica, found from New York to Michigan and north to Canada, has longer spores.
 P. pelliculosa has a general resemblance to Hypholoma dispersum, a species found in northern North America and Europe.
