The author reports the finding of Crepidotus microsporus (Karst. ss. Romell) Pilát in Bohemia, previously known only from Finland and Sweden. The specimens were collected from dead branches of Robinia pseudoacacia near Všeradice. Comparison with other species suggests it is most closely related to Crepidotus variabilis.
