The author reports a find of Pleurotus eryngii (DC. ex Fr.) Quél. in southern Slovakia, where it grows in association with Eryngium campestre L. on steppe grassland. It is a very rare species in Czechoslovakia, previously known from only five localities. Its ecology, Mediterranean distribution, and possible saprotrophic or parasitic relationship with Apiaceae roots are discussed.
