A Wing Moss - Herzogiella seligeri
Plants: Pleurocarpous, growing in slender, interwoven mats, pale green, sometimes with yellow tones (FNA 2014), shiny (Lawton 1971). Stems prostrate to upwardly inclined, sometimes reaching 3 cm in length and to 3 mm in width (FNA 2014), branching erratically (Smith 1980); central strand obscure if present; hyalodermis sometimes obscure; rhizoids few, papillose; pseudoparaphyllia lacking (FNA 2014).
Leaves: Arranged in several rows along the stem, spreading quite widely (FNA 2014) and frequently curving toward one side near the stem and branch ends (Lawton 1971), 1-2.5 mm in length, to 0.9 mm in width, cupped, neither pleated nor wavy, egg- to lance-shaped, the acumen sometimes long; base not extending down the stem or only slightly so (by up to 3 cells); leaf edges flat, saw-toothed, sometimes finely so (FNA 2014), occasionally smooth below (Lawton 1971); costa mostly short and paired, seldom absent; branch and stem leaves akin (FNA 2014).
Leaf Cells: Laminal cells somewhat long and thin, tapering at both ends, smooth; basal laminal cells usually porose, obscurely so above; alar cells square or short and oblong, or occasionally more rounded and swollen, green (FNA 2014).
Fruit ripens in summer (FNA 2014).
Herzogiella seligeri is characterized by strongly bowed capsules and the arrangement of leaves in several longitudinal rows along the stem (FNA 2014).
North American Range
Found west of the Rocky Mountains. Canada: BC and AB; USA: WA and OR, ID, MT (FNA 2014). Known in Montana from Flathead and Lake Counties (Elliott and Pipp 2016).
Decayed wood and tree bottoms in coniferous forests. Usually occurring at elevations of 980-2950 feet, occasionally reaching 6230 feet (FNA 2014).
Autoicous, with perichaetia and perigonia near the stem bottoms. Seta 15-25 mm tall, russet, frequently spiraled. Capsule 2-3.5 mm in length, somewhat russet, tilted, strongly bowed, shrunken below the opening when dry; operculum cone-shaped; exostome teeth 16, with a network of fine ridges below and papillae above; endostome processes 16, papillose, slender and keeled.
