Description:Genus Description - Plants rather slender to coarse and robust, dull or somewhat shiny, dirty-green, yellow, or golden-brown, never blackish. Secondary stems mostly elongate, spreading, curved-erect or pendent, usually remotely and irregularly pinnate. Leaves loosely appressed or spreading, strongly plicate, and often crisped-undulate at the tips when dry, erect-spreading to spreading when moist, gradually long-acuminate from an ovate base, moderately auriculate; margins bordered by longer, smooth cells, serrulate to serrate; costa ending in the acumen; cells oblong-rhombic to narrowly elliptic or linear, thick-walled, porose, unipapillose (or rarely smooth), long, porose, and smooth at the base, rounded in the auricles. Setae elongate, warty-papillose; capsules erect, subglobose, brown; operculum small, obliquely short-rostrate; exostome teeth narrowly lance-acuminate, yellowish below, pale above, papillose; endostome shorter, with a low basal membrane, narrow but often keeled, papillose segments, and no cilia. Calyptrae small, conic-cucullate, naked or sparsely hairy.
Discussion:The strongly plicate, acuminate leaves are moderately auriculate at base. The leaf cells are generally unipapillose, and those elongated in a few marginal rows often form a noticeable border.
