Overview
Hypnaceae is a large family of moss with broad worldwide occurrence1] in the class Bryopsida, subclass Bryidae and order Hypnales. Genera include and Ptilium.
Ecology
Some of the family species occur on the floor of Canadian boreal forests; an example of this occurrence is within the Black Spruce/Feathermoss climax forest, often having moderately dense canopy and featuring a forest floor of feathermosses including, Hylocomium splendens, Pleurozium schreberi and Ptilium crista-castrensis.[2]

Plants small to robust, 0.5-- -15 cm, 1--2-pinnate or irregularly branched; pseudoparaphyllia filamentous to foliose, toothed or blunt; axillary hairs 3--4-celled. Stems with or without hyalodermis, with or without central strand. Leaves of stem and branch similar but branch leaves tend to be smaller and narrower and with alar cells less well differentiated; broadly to narrowly ovate; margins sinuate to entire proximally, toothed to entire distally, sometimes recurved near base and usually plane distally; apex acuminate or acute; costa double or obscure, usually confined to proximal 1/4 of leaf; leaf cells usually smooth, usually elongate and somewhat vermicular, alar cells often differentiated as a distinct group of enlarged or diminished cells, often shorter than those of the rest of the leaf, indentation just above the alar region sometimes present. Sexual condition autoicous, dioicous or phyllodioicous; inner perichaetial leaves erect, ovate to lanceolate or subulate, abruptly narrowed to a slender acumen, serrate or entire, plicate or not, outer leaves reflexed, costa single, double, or absent. Seta smooth, yellowish to reddish. Capsule erect, inclined or horizontal, varying from long-cylindric to ovoid, usually curved, annulus 1--3 seriate to scarcely differentiated; operculum conic to rounded-mammillate; peristome double, exostome teeth subulate-acuminate, yellowish to brownish, outer surface with distinct zigzag line and lamellae, finely cross-striolate basally, hyaline and papillose distally, inner face trabeculate; endostomial segments about as high as exostomial teeth, pale and yellowish, carinate, weakly to strongly split between articulations, minutely papillose, cilia 1--3 or sometimes rudimentary. Calyptra cucullate, naked.[1] [more]

Isopterygium
Plants small to medium-sized, in thin to dense, light- to yellowish-green glossy mats. Stems 4--5 cm, creeping, simple or sparingly and irregularly branched, cortical cells small and thick-walled in cross section, surrounding larger, thinner walled cells, central strand usually absent; rhizoids smooth, on ventral surface of stems and branches just below juncture of leaves; axillary hairs with one brownish short-rectangular cell and one hyaline elongate apical cell; filamentous pseudoparaphyllia present, of 3--6 cells in 1 row or rarely with 2 rows at base. Leaves of stems and branches similar, rigid or flaccid, crowded and imbricate to remote, erect-spreading or squarrose, commonly complanate-foliate, sometimes wrinkled and contorted when dry, smooth, flat or somewhat concave, symmetric or asymmetric, nondecurrent or rarely with 1--2 cells decurrent, ovate or lanceolate, acute to acuminate; margins plane to erect, sometimes recurved at base, serrulate above the middle, mostly entire below, sometimes entire throughout; costa short and double, sometimes lacking; cells often flexuose, thin to firm-walled, linear-fusiform, smooth, with walls not pitted or occasionally those of basal cells pitted; alar cells usually clearly differentiated, quadrate to rectangular, rarely transversely elongate. Specialized asexual reproduction sometimes present on stems and branches, of uniseriate, often branched, filamentous, multicellular bodies with papillose cells. Sexual condition autoicous or rarely dioicous; perigonia scattered along stems; perichaetia at base of stems, leaves oblong-lanceolate, gradually acuminate, margins plane. Seta solitary, yellow, brown or reddish brown, 0.5--3 cm, usually twisted, straight to curved, smooth. Capsule inclined to cernuous, sometimes erect, straight or arcuate when mature, brown to red-brown, cylindric, ovoid or ellipsoid, smooth, usually contracted below mouth and sometimes wrinkled at neck when dry; operculum conic to short-rostrate, shorter than urn; annulus lacking; peristome double, exostome teeth cross-striolate below, papillose above, bordered, trabeculate at back; endostome with high to low basal membrane, segments keeled, cilia shorter than segments, in groups of 1--3, sometimes lacking. Calyptra cucullate, smooth, naked. Spores spherical to ovoid, smooth or minutely papillose.[2] [more]
