Ex affinitate H. Loxensis et lithophili, differt; a priori, cum 
speciminibus Humboldtianis comparatum, colore obscuro, foliis 
latioribus acutis, nec acuminatis, cellulis densioribus, nec perspicuis, 
pericliætialibus latioribus, externis rotundato-ovatis, acutis, interioribus 
oblongo-lanceolatis integerrimis, cellulis densioribus; ab Hypno 
lithophilo foliis late oblongo-ovatis, nec rotundatis longe distat.
