Bryum argenteum is a small moss that forms dense patches of silvery-green plants no more than 1 cm in height. The broadly ovate leaves are closely appressed to the stem and have a short, sharp tip. The silvery hue to the plants is due to the fact that the upper cells of each leaf lack chlorophyll .
Widespread in New Zealand, especially common in urban environments but also in natural areas such as exposed sea cliffs. .
