Orthotrichum pallens var. crenulatum Vitt, Bryologist. 74: 161. 1971.

Stem leaves oblong to oblong-lanceolate, rounded-obtuse, often broadly apiculate; margins usually crenulate at apex. Seta ± 0.5 mm; urn oblong when mature, becoming strangulate when old, 1--1.6 mm, strongly 8-ribbed nearly to base; endostome segments 8, shorter than exostome; exostome teeth 8, reflexed, papillose-striate. Calyptra naked. Spores 10--14 µm.

Tree trunks, especially near their base, dry, exposed areas; 500--1500 m; Nev., Utah. Endemic.

This variety is characterized by oblong to oblong-lanceolate leaves with apiculate, broadly obtuse apices. The margins, in almost all leaves, are crenulate near the apex and the seta is short (less than 0.6 mm). The exostome is papillose-striate as opposed to papillose. There are 8 endostome segments and the capsule is strangulate when old.
