This feature must be observed on very fresh material in excellent condition. In dry, hot or windy conditions the surface of the pileus will rapidly dry out and any translucent striae will disappear. When the pileus is translucent-striate, it is also often hygrophanous (changing colour on drying). The surface of the pileus may be quite smooth over the translucent striae or pleated or grooved in tandem with the striae (see Pileus margin grooved, ribbed or pleated). If you suspect that the pileus has dried out, look around for fresher fruit-bodies under leaves or litter, or in other more protected microhabitats.

Choose this state if: the lamellae are not visible through the pileus, or at most faintly so at the extreme margin.
