Attention is drawn to the fact that, although the shape of the pleurocystidia (utriform versus lageniform and/or fusiform) plays a part on sectional and specific level in Psathyrella, sometimes this pattern is broken by variants with uniform pleurocystidia within species normally with lageniform and/or fusiform pleurocystidia. Five examples are discussed, viz. P. umbrina, P. bipellis, P. obtusata, P. prona, and P. ocellata.
