Notes     (Last Modified On 3/16/2009)
general taxon notes:
Grimmia montana is characterized by the following features: 1) small plants in dense tufts; 2) leaves with a long, toothed awn, keeled above, and narrowly lanceolate from an ovate base; 3) leaf margins plane; 4) basal marginal leaf cells quadrate to short-rectangular, with transverse walls much thicker than longitudinal ones, and basal juxtacostal elongate; 5) setae straight, longer than capsules; 6) capsules erect, exserted, with obliquely beaked opercula; 7) calyptrae cucullate; 8) stomata absent; and 9) annuli wanting or poorly developed. It is closely related to G. reflexidens C. Müll. They share such common characters as small plants in dense tufts, keeled leaves with hyaline hair-points, basal marginal leaf cells with thick transverse walls, straight setae, erect, exserted capsules, and the absence of annuli. Grimmia montana differs from G. reflexidens by having plane leaf margins, obliquely beaked opercula, and a dioicous sexual condition, while the latter species has recurved leaf margins, short and obtuse opercula, and an autoicous sexual condition.
Plants of G. montana sometimes resemble those of G. donniana, but they are different from each other in basal leaf cells. The basal marginal leaf cells in G. donniana are elongate to rectangular with rather thin walls, while those of G. montana are quadrate to short-rectangular with thicker tranverse walls.
T. Cao and Vitt (1986) considered Grimmia brachyphylla Card. from Korea to be conspecific with G. montana based on the following features: 1) plants small, up to ca. 1.0 cm high; 2) leaves keeled above, ending in a long, hyaline hair-point; 3) leaf margins plane; and 4) basal leaf cells near margins quadrate, with rather thick transverse walls and the juxtacostal cells rectangular, with straight walls. However, Muñoz (2000b) treated G. brachyphylla as a synonym of Coscinodon humilis Milde.

Bryol. Eur. 3: 128. tab. 250 (fasc. 25–28. Monogr. 2). 1845. Guembelia montana (Bruch & Schimp.) Hampe, Bot. Zeitung (Berlin) 4(8): 125. 1846. Type. Norway: Felsen auf dem Donnersberg, Gümbel. April 1843 (lectotype BM, designated by T. Cao & Vitt 1986).
Plants small, up to 1.5 cm high, green to dark green above, dark brown to blackish below, in dense tufts or cushions. Stems sparsely branched, with poorly developed central strand in cross section. Leaves erect, imbricate when dry, spreading when moist, 1.7–2.4 mm long, narrowly lanceolate from an ovate base, keeled above, ending in a more or less long, spinulose, hyaline hair-point; margins plane on both sides, bistratose above; costa percurrent, consisting of nearly uniform cells or with small abaxial cells in basal part of leaf in cross section; upper cells bistratose in places, obscure, irregularly rounded-quadrate, thick-walled, 5–7 µm wide; basal marginal cells quadrate to short-rectangular, 9–23 µm × 9–11 µm, somewhat hyaline, with transverse walls thicker than longitudinal ones; basal juxtacostal cells rectangular, 23–40 µm × 5–7 µm, with thick, straight or slightly sinuose walls. Dioicous. Perichaetial leaves larger than upper stem leaves, with elongate hyaline hair-points. Setae erect, straight, yellowish, 2.0–2.4 mm long; capsules exserted, erect, ovoid-elliptic, smooth when moist, smooth or slightly wrinkled when dry, reddish brown, ca. 1.4 mm long; exothecial cells elongate-hexagonal, thin-walled; stomata none; annuli wanting or poorly developed; opercula with oblique beaks; peristome teeth single, erect, sometimes reflexed when dry, lanceolate, reddish brown, irregularly cleft and perforate above, both outer and inner surface coarsely papillose throughout. Calyptrae cucullate. Spores yellowish, smooth.
