After some days with temperatures below freezing point, I was out skating at some lakes at the outskirts of Oslo in Norway. After a while I noticed something on the ice. To my astonishment it was a dead frozen frog.

Stemonitis axifera is a species of slime mold. It fruits in clusters on dead wood, and has distinctive tall reddish-brown sporangia, supported on slender stalks. The species was first described as Trichia axifera by Jean Baptiste François Pierre Bulliard in 1791. Thomas Huston MacBride transferred it to the genus Stemonitis in 1889. Stemonitis fasciculata and Stemonitis smithii are synonyms.
