This moss was distributed as O. anomalum Hedw.,but it bears no 

 resemblance to that species. It is allied to O. cribrosutn C. Miill. 

 from the Chukchi peninsula, Siberia, chiefly by the shape of the capsule 

 and the structure of the peristomial teeth, but it differs from it by its 

 larger size and the leaf-areolation, composed of less incrassate and less 

 papillose cells. In O. cribrosum the leaf-cells are strongly incrassate 

 and coarsely papillose from the base.
