Amphidium lapponicum is crisped/contorted when dry and long lanceolate. Most remarkable are the abundant papillae
on the laminal cells that are described as large and warty (FNA vol. 28, pg. 39). Another useful trait is the absence of a peristome.
Many thanks to the University of Colorado Herbarium (COLO), Erin Tripp, & Dina Clark for permitting us
