--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>in loose tufts, dark green above, blackish green below, dull. <b>Stems</b> 1.5–3.5 cm, sparsely tomentose with light- to reddish brown rhizoids. <b>Leaves</b> erect-spreading, some weakly falcate-secund, crisped when dry, smooth, (3–)4–5(–7) × 0.5–0.8 mm, some leaf tips broken off, concave below, subtubulose above, narrowly lanceolate to a long, narrow subula occupied mainly by the excurrent costa, apex acute; margins serrate to serrulate in distal half; laminae 1- or 2-stratose above, sometimes 2-stratose in patches; costa excurrent, 1/4–1/3 the width of the leaves at base, abaxially toothed or papillose in distal half, abaxial ridges absent, with a row of guide cells, two stereid bands not extending above the leaf middle, adaxial and abaxial epidermal layers of cells somewhat differentiated or with a few cells enlarged in both layers, cell walls between lamina cells strongly bulging in distal part of leaf lamina; leaf cells smooth or abaxially prorate above; alar cells mostly 1-stratose or sometimes with a few 2-stratose cells, distinctly differentiated, often extending to costa; proximal laminal cells elongate-rectangular, not pitted or with few pits, (19–)24–33(–42) × (4)5–6(9) µm; distal laminal cells regularly quadrate to short-rectangular, not pitted, (5–)10–11(–16) × (4)5–6(9) µm. <b>Sexual</b> condition dioicous; male plants as tall as female plants but usually more slender; interior perichaetial leaves abruptly long-acuminate, convolute-sheathing. <b>Seta</b> 1–2 cm., solitary, brown or reddish brown. <b>Capsule</b> 1.5–3 mm, straight and erect, smooth, slightly furrowed when dry, reddish brown; operculum 1.5–2 mm. <b>Spores</b> 14–28 µm.</span><!--

|phenology=Capsules mature in spring.
|habitat=Sandstone, limestone or acidic rock outcrops, bluffs, cliff faces, and boulders in deciduous woodlands, especially along streams, rarely on bases of tree trunks, fallen trees and logs

|discussion=<p><i>Dicranum fulvum</i> has dull, blackish green plants, especially evident from the leaves on the basal part of the stems, leaves crisped when dry, broad costae that cover 1/4–1/3 the width of the leaves at base, laminae that are mostly 2-stratose in the distal half of the leaf, and erect, cylindrical capsules that are slightly furrowed when dry. It is sometimes confused with <i>D. fuscescens</i> but that species has keeled leaves in the distal half, with 2-stratose regions restricted to the margins, and horizontal capsules, whereas <i>D. fulvum</i> has subtubulose leaves, with almost entirely 2-stratose laminae above, and erect capsules. When <i>D. fulvum</i> has some of its leaf apices broken off, which is not uncommon, it can be confused with <i>D. viride</i>, which has the majority of its leaf tips absent. The usual occurrence on rock of plants of <i>D. fulvum</i> as opposed to the usual occurrence on bases of tree trunks of <i>D. viride</i> often gives some clue to their identity. Morphologically, the proximal leaf cells of the two differ: <i>D. fulvum</i> has shorter cells, averaging 24–33 µm, compared to the longer cells of <i>D. viride</i>, averaging 33–42 µm.</p>
