features
Bucklandiella microcarpa forms loose, yellow-green to olive-green, inside brown to blackish lawns. The up to 4 centimeters long, prostrate to ascending trunks are richly branched and have numerous short side shoots. The dry, moist, strongly recurved leaves are lanceolate and gradually narrowed to the tip, they are keeled at the top, the leaf margins on one side strongly, on the other side only slightly curled or even flat. A hyaline glass tip is usually present, it is usually short and toothed. The simple rib, strongly convex on the back, extends to the tip of the leaf. It is about 60 to 80 µm wide at the base and 40 to 55 µm wide at the top. Below it is two- or three-layered, above two-layered; It has 2 to 4 cells on the ventral side, and up to 6 cells on the base.
The lamina cells are elongated at the base of the leaf, rectangular, spotted and have strongly thickened walls, above which they are strongly knotty thickened, rectangular in the middle of the leaf, irregularly square to short rectangular above. They are either smooth or pseudopapillary with flat, round papillae over the cell walls. Leaf-wing cells are not or hardly differentiated, the basal leaf margins have a leaf border of 10 to 20 hyaline and mostly smooth cells.
The pale yellow seta is up to 8 millimeters long, the capsule oblong-ovoid to short cylindrical and up to 2 millimeters long. The 310 to 350 µm long peristome teeth are usually divided into two thread-like branches up to the base, the basement membrane is up to 15 µm high or absent. Spores are 12 to 14 µm in size.
