Patria. Lapponia inferior, locis subhumidis, ad po- 
pulorum radices et truncos, prope Kemi passim copiose: 
Wahlenberg. In Tirolis australis montibus legit Leh- 
mann. In Anglia ad truncos salicum prope York legit 
Spruce! 
Hypno polycarpo primo adspectu haud dissimilis, ca- 
racteribus autem explicatis toto coelo distans, Weck. 
striatae affinior et species distinctissima atque rarissima. 
Non satis nota.
