The chromosome number of Pleuridium subulatum is n = 13 (V. S. Bryan 1956; H. A. Crum and L. E. Anderson 1981; A. J. E. Smith and M. E. Newton 1968). It and P. acuminatum are morphologically similar. Pleuridium subulatum is distinguished by its autoicous sexual condition and 1-stratose lamina at leaf shoulder.

Plants very small, only up to 5 mm high, yellowish green or yellowish brown, in loose tufts. Stems erect, slender, simple. Lower leaves small and distant, the upper ones larger and crowded, loosely erect or subsecund, 3.0–3.5 mm long, gradually tapered from a narrowly ovate base to a linear or subulate acumen; margins plane or slightly incurved above the middle, serrulate near the apex; costa strong, nearly filling the entire subula; upper cells linear-rectangular, 13–20 µm × 4–6 µm, thin-walled; basal cells rectangular, 15–40 µm × 5–7 µm, thin-walled, pellucid. Autoicous. Perichaetial leaves similar to the upper stem leaves or slightly larger. Setae very short; capsules immersed, subglobose to ovoid, immature. Calyptrae cucullate. Spores not seen.

Stem leaves patent to erect-spreading, concave, lamina 1-stratose through-out; proximal leaves minute and bract-like, long-deltoid, subulate, 0.38-0.8 × 0.15-0.23 mm, entire proximally, minimally serrulate to entire distally; distal stem leaves with oblong-ovate base, apex subulate, 1.03-2.13 × 0.18-0.35 mm, entire proximally, infrequently serrulate distally; costa narrow, percurrent. Perichaetial leaves oblong-ovate, gradually narrowed to long-subulate, frequently crisped awn, 2.25-3.43 × 0.23-0.4 mm, margins entire proximally, irregularly serrate to serrulate distally in the subula; basal cells loosely rectangular; median cells irregular, subquadrate to short-rectangular to rhomboidal; distal cells in subula oblong to trapezoidal; costa percurrent, filling the tubulose subula; transverse section of costa at mid leaf with central guide cells forming a row across the width between a more restricted band of adaxial stereids and an extensive abaxial stereid band, accessory cells sandwiched in the center; innermost perichaetial leaves ovate, more or less sheathing base and acuminate tip, subpercurrent. Specialized asexual reproduction absent. Sexual condition autoicous, antheridia naked in persistent axillary leafy buds, one to several along the distal part of stem. Seta 0.25-0.53 mm. Spores 25-31.3 µm, densely and finely papillose, light orange-brown in mass.

Pleuridium subulatum (Huds.) Rab. Deutschl Krypt.-Fl. 2': 79. 1848. Phascum subulatum Huds. Fl. Angl. 397. 1762.
Plants gregarious in bright, glossy, green cushions; stems very short, 2-3 mm. high, simple or branching subapically: basal leaves distant, short, ovate-lanceolate, the upper ones longer, more crowded, erect or subsecund, lanceolate-subulate, the blade in cross-section often of two layers of cells on each side of the costa, also sometimes sporadically toward the margin; awn minutely serrate, and rough on the back; perichaetial leaves 3-5 mm. long, gradually subulate, the base entire, with lax oblong cells, the awn roughly serrate, with margins incurved. Paroicous: antheridia naked in the axils of the perichaetial leaves: seta short: calyptra cucullate: capsule ovoid, 0.75-1 mm. long, apiculate: apex small and blunt, straight or oblique: spores brown, warty, 21-28 ^ in diameter, maturing in March and April.
Type locality: England.
Distribution: In sandy fields, Massachusetts to Georgia and Alabama.

Pleuridium subulatum (Wechselblättriges Seitenköpfchenmoos) ist eine Laubmoos-Art aus der Familie Ditrichaceae.
Merkmale
Die Pflanzen wachsen in niederen, gelbgrünen Rasen. Die Schopfblätter sind oft einseitswendig und aus der verbreiterten, eiförmigen Basis ziemlich plötzlich in die lange Pfriemenspitze verschmälert. Die Laminazellen sind beiderseits der Rippe einschichtig und quadratisch bis rechteckig.
Die Pflanzen sind autözisch (Antheridien und Archegonien an verschiedenen Ästen an derselben Pflanze). Antheridien befinden sich in kleinen Knospen in den Blattachseln. Reife Kapseln sind gelbbraun und glänzend, Sporen fein papillös und 23 bis 28 µm groß. Die Chromosomenzahl beträgt n = 13.
Verbreitung und Standortansprüche
Vorkommen von Pleuridium subulatum gibt es in Europa, Asien, Nordamerika, Nordafrika und Ozeanien.
In Mitteleuropa ist das Moos vom Flachland bis in die untere Bergstufe verbreitet. Als Erdmoos wächst es meist in Wäldern auf kalkarmen, aber basenreichen, feuchten, offenen, sandigen, lehmigen und tonigen Böden. Oft werden auch offenerdige Stellen von feuchten Wiesen und Weiden besiedelt.
