Resembles more or less T. humile Forst. and T. filiculoides Christ. 

 Ine former differs in having the spurious vein continuons, separated from 

 the margin by a single row of very narrow cells, and the sori notforming 

 terminal panicles, the latter in having the spurious vein very distinct and 

 conspicuously flexuous, separated from the margin by 1—3 rows of broad 

 cells.— On stones in brooks; ait. 200 m.
