Leaves dense, hiding the stem, long-lanceolate to linear-elliptical and commonly weakly constricted beyond the short-sheathing base, (1–)1.5–1.8(–2) mm; apex narrowly acute to acuminate, occasionally blunt, apiculus narrowly triangular; margins 1-stratose; costa regularly excurrent into a short or long, stout mucro of several cells. Specialized asexual reproduction absent. Sporophytes absent in range of flora.
Habitat: Calcareous and noncalcareus rock, wet areas, spray of falls

Distribution
N.Y., N.C., Ohio, Tenn., e, c Asia.
Discussion
Anoectangium stracheyanum was previously treated as a synonym of A. aestivum (R. H. Zander 1977), but further study indicates that it is a good match for the Asian A. stracheyanum, in the weakly wasp-waisted, narrow leaves with a rather strong, commonly multicellular apiculus, and papillose-crenulate or weakly denticulate basal laminal margins. The “wasp-waist” referred to by Asian authors is usually just a hint of constriction just beyond the short-sheathing leaf base, and many leaves are merely straight-sided. Collections from Maine identified as A. peckii are Amphidium mougeotii.
