Notes     (Last Modified On 5/4/2009)
general taxon notes:
Grimmia elatior is one of the most robust species in the genus. It is characterized by the following character states: 1) plants up to 5–6 cm high, forming loose, rigid tufts; 2) costa strongly convex on the abaxial side of the leaf; 3) upper leaf cells 2–3(–4)-stratose, distinctly papillose; 4) basal leaf cells strongly sinuose; 5) setae arcuate and capsules finely ribbed, horizontal or pendent; and 6) peristome teeth linear-lanceolate, smooth to weakly papillose on both outer and inner surfaces. When fertile, G. elatior is easily recognized by the curved setae and ribbed capsules, which are somewhat similar to G. pilifera, but the latter has immerse capsules and the setae are shorter than the urns. In addition, Grimmia elatior differs from G. pilifera in having more robust plants, bulging costa at the back, and distinctly papillose upper leaf cells.

Plants robust, up to 5–6 cm high, yellowish green above, dark brown to blackish below, in broad, loose, rigid tufts. Stems ascending, leafless below, much branched from innovations, with more or less developed central
strand in cross section. Leaves imbricate when dry, spreading when moist, 2.8–4.0 mm long, elongate-lanceolate from an oblong to ovate base, obviously keeled above, ending in a smooth or sparsely toothed, hyaline hair-point, ca. 0.4–1.5 mm long; margins strongly revolute on one side, plane on other side; costa strong, percurrent, convex on abaxial side, with uniform or small, abaxial stereid cells in cross section; upper cells 2–3(–4)-stratose, obscure, rounded-quadrate, 7–9 µm wide, irregularly papillose, with incrassate walls; median cells 7–12 µm × 7–9 µm, sinuose; basal marginal cells shorter, with straight or slightly sinuose walls; basal juxtacostal cells rectangular, 20–36 µm × 7–10 µm, strongly sinuose. Dioicous. Perichaetial leaves similar to the upper stem leaves in shape, but larger, somewhat plicate at base, with long awns. Setae arcuate, 2–3 mm long, yellowish brown; capsules horizontal or pendent, elliptic, 8–10-ribbed when dry, reddish brown; exothecial cells variable in shape, quadrate to short-rectangular, with thin walls; stomata present near base of urn; annuli of elongate cells in 3–4 rows, with thick walls; opercula with straight, obtuse beaks; peristome teeth erect, linear-lanceolate, cribrose or irregularly 2–3 cleft above, outer surface yellowish, weakly papillose in upper 2/3; reddish brown, closely articulate, smooth in lower 1/3; inner surface nearly smooth throughout. Calyptrae mitrate. Spores not seen.
