Plagiobryoides cellularis

Plants pale pink-green. Stems 0.5–1 cm, weakly julaceous, innovations many; rhizoids few on proximal stem. Leaves crowded, imbricate when dry, erect when moist, narrowly to broadly ovate, flat or weakly concave, 0.4–1(–2.5) mm; base not decurrent, pink; margins plane or recurved proximally, 1-stratose, limbidium absent or rarely 1-stratose proximally; apex acute; costa reaching apex to very short-excurrent; proximal laminal cells long-rectangular, (60–)80–100 × 18–24 µm, 4–5:1, sometimes bulging, walls thin; distal cells elongate hexagonal, 30–70 × 16–22 µm, 2–4:1, walls thin. Specialized asexual reproduction absent. Sexual condition dioicous. [Seta thick, (1–)2–3 cm, flexuose to twisted. Capsule inclined to nutant, 2–4 mm; hypophysis strongly differentiated, elongate; operculum apiculate; peristome well developed; exostome pale yellow or tan proximally, teeth lanceolate, long; endostome hyaline to pale yellow, not adherent to exostome, segments present, sometimes longer than exostome, cilia usually absent, occasionally 1 or 2. Spores 20–28 µm, papillose, yellow-brown].

Discussion

Plagiobryoides cellularis is a widespread pantropical species. The North American material is very poor, consisting of a few small sterile shoots from two sites: on rocks near the sea on the Florida Keys and wet rock in North Carolina.
