Description

Genus Hypnum

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.

Species ca. 50: widely distributed in all continents but Antarctica, but especially temperate areas.

The genus Hypnum remains a repository for a number of discordant elements , some apparently belonging to other families. It once included a high proportion of the pleurocarpous mosses. The generic concept accepted here contains some species probably not Hypnum, but it is a reasonably natural genus that can be recognized in the field , especially when examined with a hand-lens. I have included Pseudostereodon, Breidleria and Stereodon within Hypnum, and remain unconvinced of arguments that they should be segregated. Gametophytic features are supreme in separation of species although the presence of sporophytes provides additional features that strengthen the present species concept.[1]
