Bolivia: Chuquisaca, Cochabamba, La Paz, Santa Cruz y Tarija. Distribución mundial: Caribe (La Española), Centro América, Colombia a Bolivia; amplia distribución en regiones templadas del norte y sureste de Asia.
Campylophyllum sommerfeltii is distinguished by small plant stature, squarrose to wide-spreading, triangular- to ovate subulate leaves to 0.8 mm, serrulate margins, short and forked costae, often projecting cell angles in median or upper leaf and few thick-walled quadrate alar cells. Previous names used in the tropical Andes include Campylium hispidulum (Brid.) Mitt., C. praegracile (Mitt.) Broth. and C. trichocladum (Taylor) Broth. Reports of Campylium hispidulum (Brid.) Mitt. probably apply to this species.
Campylophyllum sommerfeltii se distingue por la estatura reducida de las plantas, hojas escuarrosas a extendidas ampliamente, triangulares a ovadas subuladas hasta 0.8 mm, márgenes serrulados, costa corta y bifurcada, a menudo los ángulos de las células se proyectan en las hoja mediales o superiores y células alares cuadradas con paredes un poco gruesas. Nombres antíguos utilizados en los Andes tropicales incluyen Campylium hispidulum (Brid.) Mitt., C. praegracile (Mitt.) Broth. y C. trichocladum (Taylor) Broth. Los registros de Campylium hispidulum (Brid.) Mitt. Probablemente corresponden a esta especie.

Plants small, rather slender, forming soft mats, green, yellowish-green to -brown. Stems creeping to subascending, usually many branched; in cross-section outer 1-2 rows of cells small, thick-walled, inner cells large, thin-walled, central strand weak; paraphyllia absent; pseudoparaphyllia mostly foliose. Leaves crowded to somewhat distant, squarrose to wide-spreading, triangular-subulate to narrowly ovate-long lanceolate, to ca. 0.8 mm long, concave below, channeled distally, apex abruptly acuminate, base subdecurrent or not; margins plane or erect distally on one or both sides, recurved at base, serrulate throughout, or dentate at base; ecostate or costae short and double (forked), occasionally absent or single and short; laminal cells smooth, upper and median cells linear to linear-fusiform, at least some cells on back weakly or distinctly papillose by projecting upper cell angles, thick-walled; lower and basal cells shorter, oblong or rectangular-rounded; alar region usually differentiated, excavate, cells thick-walled and quadrate or short rectangular, often yellowish or golden. Autoicous. Perichaetial leaves differentiated, enlarged, outer series ovate-subulate, inner leaves oblong- to lanceolate-subulate, sheathing. Setae to ca. 15 mm long, slender, often twisted. Capsules suberect to horizontal, urn short cylindrical, to 2.5 mm long, ± curved and asymmetric, often constricted below mouth when dry; exothecial cells oblong-rectangular or -hexagonal, ± thin-walled; annulus present, in 2 rows; opercula conic-apiculate; peristome with exostome teeth cross-striate, tips finely to coarsely papillose, bordered and trabeculate; endostome segments keeled and perforate, finely papillose, cilia 1-2(3), nodose. Spores finely papillose.


Plantas pequeñas, bastante delgadas, formando matas suaves, de color verde, pardo- a verde-amarillento. Tallos reptantes a subascendentes, generalmente muy ramificados; en corte transversal 1-2 filas de células externas pequeñas con paredes gruesas, células internas grandes con paredes delgadas, cordón central débil; paráfilos ausentes; pseudoparáfilos generalmente foliosos. Hojas agregadas hasta algo distantes, escuarrosas hasta ampliamente extendidas, triangular-subuladas hasta angostamente largo ovado-lanceoladas, ca. 0.8 mm de largo, cóncavas abajo, distalmente acanaladas, ápices abruptamente acuminados, bases subdecurrentes o no; márgenes planos o erectos distalmente en uno o ambos lados, recurvados en la base, serrulados en toda la hoja o dentados en la base; ecostadas o con costa corta y doble (bifurcada), ocasionalmente ausente o simple y corta; células de la lámina lisas, células superiores y medias lineales a lineo-fusiformes, por lo menos algunas células con el envés débilmente o conspicuamente papiloso por proyecciones superiores de los ángulo de la célula, pared celular gruesa; células inferiores y basales cortas, oblongas o rectangular-redondeadas;  región alar generalmente diferenciada, células con pared celular gruesa, cuadradas o corto rectangulares, excavadas, a menudo amarillentas o doradas. Autoicas.  Hojas periqueciales diferenciadas, agrandadas, series externas ovado-subuladas, hojas internas oblongo- hasta lanceolado-subuladas, amplectantes. Setas ca. 15 mm de largo, delgadas, a menudo torcidas. Cápsulas suberectas a horizontales, urna corta cilíndrica, 2.5 mm de largo, ± curvada y asimétrica, a menudo constricta debajo la boca en seco; células exoteciales oblongo-rectangulares o -hexagonales, con paredes ± gruesas; anillo presente, en 2 filas; opérculo cónico-apiculado; peristoma con dientes del exostoma con estrías cruzadas, puntas finamente a gruesamente papilosas, bordeados y trabeculados; segmentos del endostoma carinados y perforados, finamente papilosos, 1-2(3) cilios, nodulosos. Esporas finamente papilosas.
