general taxon notes:

 

This species is characterized by having double or forked costae. It is related to Hylocomiastrumhimalayanum, but differs by having bipinnately branched stems; the latter usually has tri-pinnately branched stems. Hylocomiastrumhimalayanum is endemic to Eastern Asia, from the Himalayas to Japan, while H. umbratum is more widely distributed.
