The fruit of this moss is reported to resemble that of G. trichophylla, but 

 the plant differs from that species in the leaves which are crowded at the 

 apex of the branches, and are more rigid, with rougher hairs and all the basal 

 cells shorter, more quadrate and not at all sinuose, and in the areolation it 

 differs in the same way from G. Muehlenbeckii, as well as in the terete, rounded 

 nerve. Perhaps it comes nearest to G, Hartmani, but is far more diminutive, 

 and with different areolation.
