--><span class="statement" id="st-undefined" data-properties=""><b>Stem </b>leaves appressed, concave, lamina 1-stratose; proximal leaves minute and bract-like, deltoid, acuminate, 0.80–0.85 × 0.35–0.38 mm, entire proximally, serrulate distally; distal stem leaves broadly ovate-lanceolate, 0.85–1.35 × 0.38–0.55 mm, entire proximally, infrequently serrulate distally; costa broad, percurrent. <b>Perichaetial</b> leaves obovate, abruptly subulate with an excurrent tip, 1.2–2.2 × 0.30–0.75 mm, margins entire proximally, erose-serrulate distally especially at shoulder; basal cells loosely rectangular; median cells irregular, subquadrate to short-rectangular to rhomboidal or trapezoidal; distal cells at shoulder shorter, rhomboidal; costa percurrent to excurrent, narrower proximally, widest at shoulder, filling the tip, which is less than 1/4 of the leaf length, 0.25–0.55 mm; transverse section of costa at mid leaf showing adaxial guide cells extending across costa, an extensive abaxial band of stereids, and a few thin-walled accessory cells in the center; innermost perichaetial leaves oblong with an acuminate tip, subpercurrent. <b>Sexual</b> condition paroicous, antheridia naked in the stem leaf axils. <b>Seta</b> 0.2–0.25 mm. <b>Spores</b> (23–)27–33 µm, densely and finely papillose-spinulose, light orange-brown in mass.</span><!--

|discussion=<p>A chromosome count has not been reported for <i>Pleuridium sullivantii</i>. Sterile innovations are common, julaceous, solitary, to 5 mm, with leaves bract-like to oblong-acuminate. Some collections have been misidentified as other species of <i>Pleuridium</i> chiefly because the leaves may appear patent and not tightly julaceous. However, <i>P. sullivantii</i> is the only species in the flora producing (1) appressed, julaceous leaves on the stem, (2) obovate perichaetial leaves which are abruptly subulate and excurrent, (3) erose-serrulate margin at leaf shoulder, and (4) frequently seemingly stand-alone, julaceous asexual innovations.</p><!--
--><p><i>Pleuridium</i> mexicanum Cardot has been recently found in California. It would key to <i>P. sullivantii</i> but differs by having entire perichaetial leaves and vermiculose spores.</p>
