Notes     (Last Modified On 3/16/2009)
general taxon notes:
Grimmia decipiens is characterized by having robust plants, often forming hoary tufts. The leaves are keeled and ending in long (more than 1/3 the laminal length), hyaline hair-points that are strongly denticulate and decurrent. The basal marginal leaf cells are short, with thick, transverse walls. The setae are distinctly arcuate. The capsules are pendent and 8-ribbed. Gametophytically, G. decipiens may be confused with G. pilifera, but it differs from the latter by having much longer hyaline hair-points (up to 1/2 the laminal length), which are decurrent and strongly denticulate.

Handb. Skand. Fl. (ed. 8), 386. 1861. Dryptodon decipiens (Schultz.) Loesk., Stud. Morph. Syst. Laubm. 111. 1910. Trichostomum decipiens Schultz, Prodr. Fl. Starg. Suppl. 70. 1819. Type. Germany: “ad saxa granitosa rarius. -ad pagum Gevezien an der Landstrafse. Junio c. operculo.”
Plants robust, up to 3 cm high, yellowish green to green above, dark brown to black below, in dense or loose, hoary tufts. Stems moderately branched, with more or less well developed central strand in cross section. Leaves imbricate, erect when dry, erect-spreading when moist, 3.1–3.6 mm long, lanceolate to broadly lanceolate, keeled above, ending in a long, hyaline hair-point; hair-points 0.7–1.3 mm long, decurrent at margin of apex, strongly denticulate; margins recurved on one or both sides; costa strong, percurrent, in transverse section with small abaxial cells in basal part of leaf; upper cells bistratose in places, irregularly short-rectangular, 7–12 µm × 5–7 µm, with thick and sinuose walls; median cells rectangular, 9–18 µm × 5–7 µm, strongly sinuose; basal marginal cells short, rectangular to short-rectangular, 14–23 µm × 9–11 µm, with transverse walls thicker than longitudinal ones; basal juxtacostal cells narrowly rectangular, 23–46 µm × 7–9 µm, with sinuose walls. Autoicous. Perigonia often located just below the perichaetia. Setae long, arcuate, twisted when dry; capsules pendent, elliptic, 8-ribbed; exothecial cells variable in shape, mostly rectangular-hexagonal, thin-walled; stomata present at base of urn; annuli consisting of well developed elongate cells with thick walls; opercula with long, straight or slightly oblique beaks; peristome teeth single, erect, lanceolate, yellowish brown, imperfectly cleft in 2–3 branches and perforate to the middle, outer surface densely papillose above, sparsely papillose or nearly smooth below; inner surface papillose throughout. Calyptrae mitrate. Spores 12–16 µm in diameter, yellowish brown, granulose.
