This treatment of Weissia controversa follows the study of A. Stoneburner (1985), which justifiably included W. andrewsii, and, agreeing with H. A. Crum and L. E. Anderson (1981), pointed out the great variation in peristome development including occurrence of both eperistomate and peristomate capsules in the same collection. The present treatment includes all flora area reports of W. condensa, a morphologically distinct European species with characters as listed in Excluded Species. Rhizoidal gemmae were reported by W. D. Reese (1988) but these are apparently rare. Weissia viridula Bridel is an illegitimate name that has been much used for this taxon.

Plants small, 4–6(–10) mm high, bright green or yellowish green, in dense tufts. Stems erect, simple or irregularly branched. Leaves often crowded at stem tips, crisped when dry, spreading when moist, narrowly lanceolate, sheathing at base, upper lamina often channeled, acuminate at apex; margins strongly incurved above the leaf base, entire or crenulate by projecting papillae; costa rather stout, usually shortly excurrent, ending in sharply mucronate tips; upper leaf cells rounded hexagonal, thin- to evenly thick-walled, papillose, with bifid or branched papillae; basal cells sharply differentiated, rectangular, sometimes forming a V-shaped leaf base, mostly thin-walled, smooth, hyaline. Autoicous. Setae 5–8 mm long; capsules erect, oblong-ovoid; opercula conic-rostrate, with an oblique beak; peristome teeth short, linear-lanceolate, papillose or sometimes rudimentary.

Listki wąsko lancetowate, często stłoczone na końcach łodyżek, poskręcane w stanie suchym, rozpostarte gdy wilgotne. Powyżej podstawy listka brzegi blaszki silnie podwinięte. Żebro dość grube^[6].
Sporofit: Seta o długości od 3^[3]–5^[6] do 8 mm. Puszka zarodni podłużnie jajowata do cylindrycznej, wieczko opadające. Perystom o 16 zębach szczątkowych do lancetowatych, sporadycznie niewystępujących^[3].

Puszki, z wieczkiem (lewa), z widocznym perystomem (prawa)
Zarodniki

Biologia i ekologia

Puszki dojrzewają w przeciągu roku, w zależności od obszaru występowania rośliny. Rośnie na glebie, skałach, terenach ruderalnych, zachwaszczonych, poboczach dróg i polach o kwaśnym lub wapiennym podłożu.^[3]
