But I’m excited to find U. terrefacta! Pin pricks all over, super neat :)

Consider U. torrefacta, too

Check the underside. U. torrefacta has tattered plates, U. hyperborea should be fairly smooth. The real telling character for torrefacta is the pin-pricks: hold it up to the light and see if it’s perforated all over. Many species can do this to a limited extent, but when you see torrefacta it’s like a slap upside the head: “oh, that’s what they mean!”
