Aulacomnium heterostichum (synonym Arrhenopterum heterostichum), commonly called goose-egg moss or star moss, is a species of moss in the family Aulacomniaceae.[1] It occurs in two widely disjunct regions: eastern North America (the eastern United States and Canada) and eastern Asia (China, Korea, Japan and the Russian Far East).[1] In its North American range, it is commonly found on slopes growing directly on soil or, occasionally, at the bases of trees.[1]
