This species was formerly known only from a single place 

 in Greenland, Godthaab (Rosenv. Deux. Mém. 1. с). The spe- 

 cimens I have had for examination occurred in company with 

 TJlothrix consociafa Wille and were all young and small. The 

 stipe was 102// long, the head 51 /г long and 6// broad. The 

 head is distinctly marked from the stipe by a constriction. 

 it was collected sterile in July in the littoral region.
