Ecología: Montano alto abierto a páramo y puna húmeda; sobre suelo y rocas, usualmente asociadas con corrientes y ríos. Elevación: 2900-3500 m (Colombia: 3300-3500 m, Bolivia: 2900 m). Distribución: Ampliamente distribuida en el Hemisferio Norte.
 
Hygrohypnum luridum is characterized by medium sized stature, often yellowish brown or green, pinnately to irregularly pinnate branched, small, thick-walled epidermal cells (hyalodermis absent), erect to falcate, concave, ovate to oblong-ovate leaves to 1.5 mm, gradually acute to acuminate apices, entire margins (or serrulate at apex), single or forked costa to 2/3 leaf length, entire and ± thick-walled median and upper cells, and small, well differentiated alar region with cells irregularly quadrate to short rectangular. Only known from a single collection (cf. Hedenäs 2003: 86). Hypnum mandonii Schimp. in Müll. Hal. nom. nud. is based on a collection made by Mandon in 1861 (La Paz, Bolivia).

Plants medium-sized, green to yellowish-green or brown. Stems pinnately to irregularly branched in one plane, few branched; in cross-section hyalodermis absent, central strand usually present; paraphyllia absent; pseudoparaphyllia triangular. Stem leaves erect to erect-patent, straight to falcate (gradually curved), often second, ovate to oblong-ovate, concave, smooth, not plicate, apex short acuminate to acute, rarely obtuse; margins entire to weakly serrulate at apex; costa variable on same plant, single and forked (or branched), 1/2-2/3 the leaf length; upper and median laminal cells linear, slightly to notably thick-walled, smooth, walls entire, not porose; alar group well differentiated, quadrate or short-rectangular in shape. [Autoicous. Setae enlongate, red. Capsules horizontal, urn cylindrical to short-cylindrical, curved; peristome well developed, exostome cross-striate below, papillose above, endostome basal membrane high, segments narrowly perforated or not, cilia 0-3(4), as long as segments. Calyptrae cucullate, naked. Spores lightly papillose.]

 

Plantas medianas, de color verde hasta verde-amarillento o pardo. Tallos pinnados a irregularmente ramificados en un plano, poco ramificados; sin hialodermis en corte transversal, cordón central generalmente presente; paráfilos ausentes; pseudoparáfilos triangulares. Hojas del tallo erectas a erecto-patentes, rectas a falcadas (gradualmente curvadas), a menudo secundas, ovadas a oblongo-ovadas, cóncavas, lisas, no plegadas, ápices corto-acuminados hasta agudos, rara vez obtusos; márgenes enteros a débilmente serrulados en el ápice; la costa varía en la misma planta, simple y bifurcada (o ramificada), ocupando 1/2-2/3 de la longitud de la hoja; células superiores y mediales de la lámina lineales, con paredes escasamente a marcadamente gruesas, lisas, paredes enteras, no porosas; grupo alar bien diferenciado, de forma cuadrada o corto-rectangular . [Autoicas. Setas largas, rojas. Cápsulas horizontales, urna cilíndrica a corto-cilíndrica, curvada; peristoma bien desarrollado, exostoma con estrías cruzadas abajo, papiloso por encima, membrana basal del endostoma alta, segmentos angostamente perforados o no, 0-3(4) cilios, tan largos como los segmentos.
