A new hairy Leptogium from Nepal.

The new species Leptogium sphaerosporum from Langtang in Nepal is described. It is closely related to L. pedicellatum, but differs in being more delicate with phyllidia and having spheroid spores. It is most probably a local species of the lower montane forests. An emendation to the world key of hairy Leptogium species is presented.
