Lopidium concinnum has a prostrate creeping primary stem that forms erect secondary branches (stipes). Each stipe terminates in a linear-to-triangular frond with pinnate branches (branches regularly arranged in one plane to either side of the frond axis). There are two rows of pale greyish-green leaves (lateral leaves) that spread outward from the stem. There is an additional row of smaller, circular-to-oblong leaves (underleaves) on the lower side of the branch.

 Widespread in New Zealand in damp forest on tree trunks, old logs and rock.
