Plants small, loosely caespitose, yellow- green; terricolous. Stems 2-4 mm tall, occasionally branched below; in section round, central strand small, cortical cells incrassate, outer row smaller. Leaves contorted-incurved dry, erect-spreading wet; linear-lanceolate, to 2 mm long; apex acute, weakly cucullate, mucronate; base oblong; margins narrowly incurved, entire. Costa short-excurrent, ventral superficial cells elongate, smooth, dorsal superficial cells long- rectangular, smooth; in section oval, guide cells 4, ventral stereid band strong, 2-3 cells thick, ventral surface cells undifferentiated, dorsal stereid band 3-4 cells thick, dorsal surface cells undifferentiated. Upper laminal cells quadrate, thin-walled, papillae on ventral surface large, branched, 1-2 over lumen, on dorsal surface low, numerous, scattered; basal cells rectangular, hyaline, smooth, thin-walled. Autoicous. Perichaetia terminal, leaves similar to vegetative leaves, but slightly larger. Seta 2-3 mm long, yellow; capsule hymenostomaceous, oval, constricted at mouth, 0.8-1.0 mm long, reddish yellow; peristome absent; operculum rostrate, 0.3- 0.4 mm long; spores round, 25 µm, strongly papillose.

The small, linear-lanceolate leaves, acute-cucullate apices and hymenostomaceous capsules help to identify W. cucullata. The spores are also larger than those of any other Southern African species of Weissia. From: Magill, RE. 1981. Ditrichaceae to Grimmiaceae. In: OA Leistner (ed.). Fl. S. Africa Bryophyta(1,1): 83-281. Botanical Research Institute, Department of Agriculture and Water Supply, Pretoria. [https://doi.org/10.5962/bhl.title.119879] [CC BY]

Endemic to Southern Africa, this species is known only from the type specimen. The original collection was made by Breutel, in the mountains near the mission station at Gnadenthal, in the southwestern Cape. From: Magill, RE. 1981. Ditrichaceae to Grimmiaceae.
